[ZNM/W-MBUS] Does the Zigbee module such as RC2400-ZNM have the same footprint as the OMS \RC1180-MBUS3? If yes, is our OMS board could be used also for the Zigbee module?
[Wireless M-Bus] regarding the M-Bus packet frame, there are two fields named C-field and CI-field, for which I could not find explanation from Radio Crafts M-Bus user manual. Please send us the details of the documents explaining C and CI fields.
[Wireless M-Bus] “The W MBus network will contain repeaters to transmit data from 868 MHz to 169 MHz. We want repeaters in Battery operated mode. 1. We plan to put Repeaters in long sleep mode and arrival of packet from nodes would wake Repeater. This design would be similar to Data collector/Concentrator design envisaged in Wireless M Bus specs. Alternatively we can design time synchronized wake-up algorithm so that all nodes wake up at the same time (including repeater) and after data transmission, all nodes go back to sleep mode. What would you recommend?”
[W-MBUS]”We have a board for Wireless M-Bus which is connected one of the UARTs at the Arm Cortex A5 which we are using. Now we have had some units which have stopped working. We got one to the office last week and this one seems not work at all. We could not send the configuration commands etc. “
[W-MBUS] What kind of CSMA algorithm your module uses? We are worried about compatibility with a 802.15.4 network which should coexist with your module (MBUS3). Will the module detect traffic on the same frequency, and avoid sending at the same time when other two devices communicate? We are not sure about vice-versa also, and we use Atmel at86212 CHIP, on 868 Mhz. (868.3 Mhz, BPSK 20 kbps)
[W-MBUS] What I’m searching for is this switch to turn off the transmitted ID of the module. I want to add this MBus-ID within my µP and send it via UART to the module. The reason is, that we probably need to send some MBus T1 pakets with different MBus-IDs.
[W-MBUS] We want to test MBUS protocol. It´s not for metering. If weuse MBUS protocol , must we follow the protocol for wake up/ sleep?
[W-MBUS] We are working on the RC1701(HP)-MBUS4. We are using the MBUS packet sniffer in the MBUS Demo application. Is possible to get better resolution of the timestamps in the demo application. Is it possible to get microsecond or millisecond granularity instead of full second?
[W-MBUS] We are using RC1180 HP WMbus module. We are using S1 mode and we are considering moving also to T1 mode that the module manage. Can you please confirm that dataframe between S1 & T1 is the same
[W-MBUS] The W MBus network will contain repeaters to transmit data from 868 MHz to 169 MHz. We want repeaters in Battery operated mode. Do you have module satisfying our repeater requirement?
[W-MBUS] Since the user manual aslo states (again at pag. 4) that “When blue data appears, it doesn’t guarantee that this data has been sent over RF, it has been sent into the serial port only, as this depends on the state of the RF module”, I suspect that the RF module can be in different “states”. Is it true? Wich are these states? How can we handle them?
[W-MBUS] Say we have 1 central unit with 1 wMBus receiver and another wMBus device with bi-directional communication, can the central unit operate in T2 mode and communicate with both types of end devices?
[W-MBUS] it seems that collisions between slaves create sometimes bit errors and the correction in your Errata Note 4 seems to solve it. However we are surprised that because of bit errors are present in a radio frame, this frame is not rejected (wrong checksum for example) and it is still analyzed (and in this case to find a non-supported encryption mode). Why ? Is there a risk to receive a frame from the RC1180 radio module with wrong data due to collisions ? “
[W-MBUS] Is there a way to configure the RC1180-MPC1 for half litre pulses? If not can the firmware be updated to have a setting for this?
[W-MBUS] Is it somehow possible to set the 4 Byte DID just like the 1 Byte DID in the volatile memory?
[W-MBUS] Is it correct to configure the M field and the A field with the same value for both repeater and concentrator, if not what is the suggested configuration
[W-MBUS] In your RC1180-MBUS datasheet, we can see that the frequency tuning can change between 2 channels in mode S and T (868.3 and 868.95MHz). We chose the 868.95MHz for our transceiver and I would like to know for our test after the production what is the frequency tolerance and if there is a frequency calibration.
[W-MBUS] I would like to know what is the exact configuration and settings on the MBUS Demo tool to setup a repeater between a slave and a master?
[W-MBUS] I would like to ask you, if the 1701HP uses 5V or 3.3V logic level for the I/O’s (CONFIG, RESET, etc.)
[W-MBUS] I understood that RC1180 mbus3 is the RF module to attach with the meter to get the meter reading remotely. Can we attach this to all types of meters (existing meters)? Or it requires the meter to be replaced with a new one?
[W-MBUS] I sent a OMS telegram (A) to RC1180 and I tried to view data telegram with MBUS Demo Snifer ( MasterMBUSReveive.jpg), but I don’t found any CRC.
[W-MBUS] I need to realise a smart metering network using 169 MHz and WMbus standard. What option do you have?
[W-MBUS] I have one development board Wireless M-Bus (RC1140) that we got in 2010. HW version 1.2. I’m pretty sure this is out of date in software revision. Could you please advise latest FW revision and procedure to upgrade?
[W-MBUS] I have another question, there is a command to use to read the key of one of the installed slaves (set with command 0x4B)?
[W-MBUS] I have a question about version protocol. Wet uses the old version of the protocol, is this compatible to the new version?
[W-MBUS] I am asked to login for the MBUS User manual. Is there anything different about this manual or is it the one we already have ‘Manual Demo MBus’ ? If it is different, could you please forward it to me ?
[W-MBUS] How can we define, where a data package (sending out of the module) starts and when does it stops.
[W-MBUS] For RC1180, we need to be sure it is WMBus compatible and have the standard and HP versions. I understand the legal restrictions and we will probably use the standard but need to ensure the hardware is compatible with higher version in case we need to use them?
[W-MBUS] Does your device support both AES-CRT and AES-CBC. If it does do I have to make any special setting to choose either of them or will RC1180 automaticly decode the data using the information how to decrypt the packet using the MBUS status-byte? “
[W-MBUS] Do you erase between every parameter we send in one go during ‘M’ operation or does it depend on where the parameter is located in memory?
[W-MBUS] Could you provide some information about “Mode C” on RC1180-MBUS3 if it’s actually supported.
[W-MBUS] As far as the data format is concerned, the “”MBUS-CCT user manual”” states: “”To send ASCII characters, type them in and hit the enter key or click on the send once button””. In case bytes have to be sent, we know that te first byte should be the Length byte. We tried to transmit the same bytes sequence shown as an example in the user manual (pag. 4): ‘5 0x33 0x25 6 78 7’. In both cases (ASCII and bytes transmission) nothing is transmitted across the link (or at least nothing appears at the receiver side). Comments?
[W-MBUS] About the sniffer: when I configure the Sniffer as a slave, should I see all master messages to all slaves (independent of the address configuration)?
[W-MBUS] “When I activate UART_FLOW_CTRL = 3 (CTS/RTS), I didn’t succeed to receive & send datas with the RC1180 when I activate RTS/CTS on application side. “
[W-MBUS] “What happens with frames, that are received while transmitting another frame? If I understand this correctly the module returns to idle state after the frame is sent to the uart. That means, if a frame is sent, while the module is not in idle mode, it can’t recognize the second frame. Right? “
[W-MBUS] “we have an issue about the use of the 169 Module RC1701(HP)-MBUS4 fw ver 1.10 (see the attachment) We see that we can receive up to 124 Byte while we are sending 240 byte. There is some setting we have missing somewhere? “
[W-MBUS] “we have a problem with the configuration of RC1700HP(MBUS4). We start our micro and we start the comunicacion for the uart with the radiocraft RC1700HP likewise with the RC1180 MBUS3 (with a low level in the nConfig pin) but the Radiocraft RC1700HP don’t responde (with the symbol >). We watch with the oscilloscope that in the pin RTS/SLEEP in this case we have a High level and in the RC1180 we have a low level, could be this the problem, you know why can be? The supply that we use for the RC1700HP is Vcc = 2.5v and Vcc_PA = 3.6v. Is this ok? “
[W-MBUS] “We do the test you proposed (DTR signal to a fixed voltage) but needs more details on how to do it. Could we set the DTR to 1 using the configuration program or must vie done in hardware? “
[W-MBUS] “We did configure one module in Sniffer mode and the other one in continuous data packet transmission. Whatever the transmission mode selected ( T2 or T1) the sniffer sees datapackets in 06 mode meaning T2 configuration. “
[W-MBUS] “We are using Radiocrafts MBUS3 and MBUS4 modules. Initially we are configuring the parameters like network address , mode in the internal Memory. In few cases the module became non responsive and if we try to read the values it returns 0xFF or does not respond . After this we cannot use the module. We not modifying the baud rate or calibration value of the module. “
[W-MBUS] “We are interested in using Radiocrafts modules in our product. We need to install around 150+ sensors per house which are connected to one concentrator (master) device. Sensor are small and therefore using external antenna is not an option which may be problematic when using 169MHz? Those sensors are installed into houses with concrete walls and range requirements are therefore at least 150+ meters in NLOS situations. We are considering to use Wireless M-BUS protocol or some similar which do not require acknowledgements from the sensor. We prefer sub 1-GHz radio because of coverage. Could you suggest some of your modules which support 150+ slaves in one network and extended range at least 150+ meters in urban area? Please also take into account our antenna limitations. “
[W-MBUS] “We are going to use RS1180-MBUS modules in our project. Please tell me how it works in a network in repeater. Is it possible to use routes in a network? “
[W-MBUS] “We are going to use RS1180-MBUS modules in our project. Please tell me how it works in a network in repeater. Is it possible to use routes in a network? “
[W-MBUS] “We are following observations on the MBUS3 repeater 1. Repeater repeats the message after Random delay we have observed it as up to 20 seconds. 2. Repeater does not repeat the message in the sequence it is received . 3. Sometimes message does not get repeated. We have tested this when with the Transmitter transmits every 3 seconds and at the receiver it is replied within 500 mSec of received message. Can you please give your comments on these observations. “
[W-MBUS] “Under which circumstances does the Radiocrafts module filter out messages ? Is it based on the C-Field on the data link layer and the CI field on the application layer ? If so, is there a way to switch this off ? “
[W-MBUS] “There is something I do not understand. In the 169 Mhz it is allowed to transmit at 500mW or +27dBm. This is specified by the module if a power supply of 5V is used for the power amplifier. However , if you want to transmit at +27dBm this means a Vpp of approximately +14.1 Volt . Is there a DC-DC convertor on board of the module ? “
[W-MBUS] “The WM-Bus module on my PoC unit sometimes stops sending serial messages (eg overnight). The Radiocrafts Demo PCB continues to receive OK, so it’s not the radio signal stopping, it’s the module serial output stopping. It starts again after turning Vdd off and on. This could be radio interference on the PCB wires perhaps, eg insufficient filtering on the serial data wires or Vdd wire, so I will improve that on the PCBA. “
[W-MBUS] “The configuration process with bus-CCT v1.02 will work fine. The problem is that they can’t send and receive data The T1 mode is their priority – RF_Channel = 12 – RF_Data_rate = 3 – MBUS Mode = 1 A test with a spectrum analyser will show no transmission. A test in reception mode does not show any reception. “
[W-MBUS] “Sometimes RC1180-MBUS3 stops responding and we found that the configuration registers in module’s flash are damaged (FFs instead of meaningful values). Do you have any suggestions what should we check on our side? Any ideas what could be the reason of the configuration lost? “
[W-MBUS] “So, does this USB stick and the PC software come with open software so we really understand what happens between the PC and the USB (RC1180-MBUS3). Which we can use to make our own implementation in our Gateway? “
[W-MBUS] “Regarding the modulation, I have a question about setting the modulation method. In my measurements , I changed the RF frequency with the volatile ‘C’ command. There is no volatile command to change the modulation method, so I left it at default. Then I find that the message transmission time at RF is the same for all channels, suggesting that the modulation scheme is the same. Is this the case, and is the default modulation valid for all channels? I need not be compatible with strict EN 13757. “
[W-MBUS] “In your mbus manual wrote (pag 4): “”In OMS (MBUS3) the master sends a command with its own address as Link Layer Address, and the slaves address as Application Layer Address.”” You mean that only long Appl header (12 byte) containing the slave address is granted ? If I got it the MUC and slaves have same link address (i.e MUC address) .. is it correct? Does your mailbox feature use this format ? “
[W-MBUS] “in order to assess the SNR threshold of my RC1700HP-MBUS device, I’m mixing the signal from the 169 MHz gateway to the Meter with a white gaussian noise signal. In order to compute the actual received noise power, I should know the amplitude of any filter present in the receiving stage. According to the standard, channels 1a/b, 2a/b and 3a/b have a width of 12.5 kHz and therefore I’m simply supposing that a filter with a bandwidth approx. equal to 12.5 kHz will be present somewhere at the receiver. Could you please confirm my assumption? “
[W-MBUS] “If they use MBUS protocol , must they follow the protocol for wake up/ sleep? They will connect the slave with a Micro so the slave will be awake by the micro. In this case can the customer control the transmission times from the slave without following the protocol. “
[W-MBUS] “I’m doing a reasearch for our new project involving AMR readout of gas/water/elektricity meters. I’m looking for a device that will be capable of reading pulses from a meter and send them wirelessly to local data logger. This has to be standalone solution as receiver has been already chosen. Do you have such device in your portfolio? “
[W-MBUS] “I’m currently working on a wireless M-Bus project, and I try to run the developement kit with meters. In fact, I get to receive a frame sent by a counter, but I can not return it even if I put the module in “”Repeaters Mode”” “
[W-MBUS] “I were unable to made RC1180-MBUS3 modules work in REPEATER mode using T frames. I have programmed the module following the User Manual procedure, show below NETWORK_ROLE = 0x002 MBUS_MODE = 0x001 Using the “”M”” command to record the non volatile memory. But it doesn’t work. “
[W-MBUS] “i tried to use with 2 demo boards the mailbox feature on a master but I failed , I didn’t see any reply fom master to slave in packet sniffer. Is it implicit ? “
[W-MBUS] “I need to sniff traffic from a master (electricity meter). So in T2 mode I need to configure the sniffer as slave, so I can see traffic from the electricity meter. But, it appears the MBUS-DEMO doesn’t support this mode? “
[W-MBUS] “I know by using Zigbee module that even if they use an “”open protocol”” it doesn’t mean you can be fully compatible with other manufacturers (aka ZB home profile, …). Is it still the same with Wireless M-BUS? Is it all about Application layer? “
[W-MBUS] “I have two more questions: – If I send a CNF_IR (or a REQ_UD2) as automatic reply, the status byte is automatically set to the RSSI value, but I want to send 0 (zero). How can I do this? – If I send a CNF_IR (or a REQ_UD2) as automatic reply, the signature is automatically set to 0xC000, but I want to send 0 (zero). How can I do this? “
[W-MBUS] “I have been asked to evaluate the possibility of incorporating a wireless MBus solution into an existing wired MBus device and came across your products in a technical magazine. What other additional devices, other than the module, may be necessary to create a small scale network. We are familiar with all aspects of electronic design so need only the basics. “
[W-MBUS] “I have a RC1180-MBUS3 and I want to read an encryption key in the register 1, registered with the ‘K’ command. Is it possible? How I can do that ? “
[W-MBUS] “I configured the MBUS radio to use the UART flow control using the CTS/RTS pins. When the host processor wants to send an MBUS message, it pulls the RTS pin low and waits for the radio to pull CTS up. The processor then sends the message. But this gives strange results, and sometimes it just fails to send the message. I also tried using only the CTS pin, where I wait for the pin to go high before sending the message. Again, this does not always work. Are the CTS/RTS pins exclusively for controlling the flow over the uart connection (host processor to radio) or are they meant to indicate when the radio can send another message ? If so, how should I use them ? “
[W-MBUS] “I activate the reception of the entire frame (start, header, rssi, crc & stop) using DATA_INTERFACE = 12. I wonder how to calculate this CRC? Is it a arithmetical sum of the following data : C field, Header, Ci field & payload as it is specified in M-bus documentation? “
[W-MBUS] “How can I make a mobile readout device with RC1180-MBUS3 (…reading heat meters from car or by walking)? How can I setup up a module? Must I use „install mode=accept all”, or should I every time before I want to collect data from heat meters use The install mode, after install mode master keys settings…? “
[W-MBUS] “Dear Radiocrafts team,, would you have a solution as to where we could take a wired mbus connection from meters and convert to wmbus or a radio signal enabling us to read the meters remotely? “
[W-MBUS] “Could you tell me if it’s possible to filter Wireless M-Bus frames on RF to accept just frames which comes from the slaves registered in the master with RC1180-MBUS3 ? “
[W-MBUS] “) I read OMS specification and now Data application Layer is much clear to me. Our goal is to use DLMS/cosem application layer over mbus. I saw in OMS specification that there is a correlation between VIF/DIF and OBIS code …but information about that are very weak. Have you got frames’ examples of DLMS Application in order to understand data exchange? “
[W-MBUS] “After different test, it seems that ‘s’ command works only in ‘RX only’ mode (test 3). Is it normal? “
[W-MBUS ] The modules we have are with memory for up to 64 devices (8 bytes for each device), binded in RC1180 internal non-volatile memory. Do you have update with more memory for this purpose?
[M-BUS] I would like to kindly ask you some information about: – the best Software Tool I should use for RC1700DK-MBUS4? The availability of the Demo Software Tool? The updated list of accepted Operating Systems?
