[TINYMESH] We need to power end device from 3xAAA cell (4.5V). The maximum pulse current of RC1180HP-TM is 560mA. In this case we need to use LDO for such current and their Iq are big. Do you have any recommendations how to solve this. In this application we have no external processor, we would like to use only inbuilt features of the Radiocrafts.
[TINYMESH] We need to burst data so that they can go back to sleep as soon as possible. If my payload is 10bytes and RF set for max range, what is the time it will take to burst to the gateway on a 15hop network and then receive the ACK before it can sleep again?
[TINYMESH] We have to used Radiocraft tinymesh product such as RC1170/71HP-TM for street light application, Question : How to update SID after deployment for same sid for Gateway device? Our requirement is to update the RF parameter such as SID,UID,Device type and other parameter first time or after filed deployment. according to your configuration in OTA update, we are able to set first time and after deploymnet configuration for only Router device . we are not able to read Get status and configure Gateway device after deployment from over the air through RF device. Please tell proper suggestion, how to update Gateway device Configure SID from over the Air through other Rf same Gateway device.
[TINYMESH] We are planning to power the device directly from 13Ah (or more) primary battery. Its nominal voltage in 3,6V (and open circuit 3.67V). Proposed type of the radiocrafts is RC1701HP-TM / RC1180HP-TM. The absolute maximum ratings of the RC are 3.9V. So I suppose there will be no problem?
[TINYMESH] We are looking for ready to use and certified module on 868MHz band with embedded mesh stack
[TINYMESH] Sometimes the allowed transmitting time is 10%. Is it handled by module’s FW or should it be handled by the external application.
[TINYMESH] some breaks in data tranfer which can take up to 0,5 second. Transmition of 8kB file takes 10 minutes. Are you able to help somehow and recommend settings to speed I up?
[TINYMESH] page 8 in the data-sheet lists HW and FW versions with 2 bytes length, but the corresponding config bytes are 4 bytes long. How are these values comparable?
[TINYMESH] Our question is when the RSSI level is updated in case of End Device operation. It is quite unconvienent to satisfy only with the first RSSI during ED’s powerup. Basically when the ED will move around or the RF environment will change how we will know it without restarting the ED’s node.
[TINYMESH] One question for RC End device mode. We need to sense two edges of a limit switch. This limit switch has pushpull output and we would like to use sleeping radiocraft tinymesh without external uC. Is it possible to switch off internal pull up at GpIo and wake up on both edges to transmit message automatically?
[TINYMESH] Is it possible to use the system IDs to spread the network load, but terminate all Gateways to 1 server?
[TINYMESH] In the recent datasheets I’ve seen (HP) TINY MESH modules. At some locations it’s likely that we’d install distant routers, i.e. in an apartment say the concentrator is at the 8-9thth floor and the router is at the basement. Can HP module be an answer for this? Or is it only a cure for long distance line of sight applications?
[TINYMESH] In the datasheet it says RTS signal may block the GWAY if held high too long. How long is that duration?
[TINYMESH] I saw that the tinymesh modules support a range of frequencies (~15). Are these fixed (i.e. static) frequencies? Or the mesh protocol is able to hop between them?
[TINYMESH] I need an information about RC1160-TM module. I want to know if is possible to configure the module as a “repeater” of the input GPIO pin: fox example the change level of the a digital input pin of the transmitter, causes the same change in in the same pin (digital output) of the receiver.
[TINYMESH] I have a query regarding the tiny mesh 868MHz module. Due to the restricted dimensions of the enclosure we would like to use the radiocrafts module in, is it possible to orientate the antennas of the gateway and routers in the network horizontally? Ideally to minimize system cost, would having a length of wire (at the 1/4 wavelength of 868MHz) soldered to the RF o/p of the module which would be perpendicular to the PCB give good range?
[TINYMESH] I am currently developing a new product using your RC1180HP-TM module and after scanning the entire datasheet, I couldn’t find specific information regarding some RF parameters, namely: modulation, bandwith and frequency deviation. I have configured the module to operate in channel 13 at full power and data rate of 76.8kbit/s.
[TINYMESH] I also would like to get more information about TinyMesh performance. Could you provide a comparison between TinyMesh and ZigBee Pro?
[TINYMESH] For debugging can I use a GW with the same DeviceID as our servers GW. (Both 0.0.0.1) most of the time, so both GWs get all data packets.
[TINYMESH] For compliance testing, does Tinymesh provide a test mode with “continuous transmission with 100% duty cycle?
[TINYMESH] Does the RF bitrate of the Tinymesh module affect the RF sensitivity, and hence the range?
[TINYMESH] CTS pin is recommended to be observed before UART is driven on a byte by byte basis in tinymesh documents. Some other paragraph tells as if it is unnecessary and only two pins are enough. How critical is that issue?
[TINYMESH] Certain data is priority, how can I quickly stop a busy network of nodes sending other data to stop while I poll for the important alarm data every 5 secs?
[TINYMESH] Can we add an external Power Amplifier to the Tinymesh module to increase the transmission power?
[TINYMESH] About compatibility of the high power and lower power nodes. Please can you explain in more detail what problems I may encounter with the 2 types, as I only see that I will loose the ACK which your data sheet explains as being present on each hop?
[TINYMESH] “We want a RC1740TM-DK but I doesn’t found this article in your price list. On your web side stand >>> contact Radiocrafts” – what does this imply? “
[TINYMESH] “We have to develop a system that it can to locate people. I have thought to use RC tiny mesh using the RSSI level, but I would need to know what router I am connected and the RSSI of that router (not all the net). Is that possible? “
[TINYMESH] “We have a doubt about the connections dynamic and network architecture. Consider the image below: 1 – Gateway, Router and End device ar configured with the same RF Power 2 – Gateway signal can reach directly to End Device 3 – Router can reach to Gateway and End Device 4 – The End Device only can reach the Router when transmitting, but receive the signal from Gateway directly Although the end device can receive the signal from the Gateway (above RSSI acceptance level), once the End Device can’t reach the Gateway directly, the connection is never established and the second way through Router is never choosed. The tiny mesh algorithm favors the shortly way to gateway if the rssi level is above acceptance level. If the end device receive the signal from Gateway above acceptance level, but is not able to reach the gateway directly, even if we have a router between Gateway and End Device the connection is never establish. Do you have any explanation to this behavior and a way to improve and avoid this kind of scenario? “
[TINYMESH] “How can I understand, when the CTS goes low, if the data have been delivered or not? If you have an alternative way to understand if the data have been delivered or not, please let me know (data going from the routers to the gateway).”

[TINYMESH] “- Are all RC2500(HP)-TM compatible to each other? – Is there a combination of RC2500(HP)-TM which cannot communicate with each other?”
[TINYMESH “We would like to make application when one measured parameter (I.e Tempearture) will be transferred in 11 floor building to basement where GSM concentrator is installed. Measuring device should transmit every 15 minutes and need to live on battery minimum 3 years. “
[Tiny Mesh] Can the END point transmit data at any moment after wake up by external trigger (i.e GPIO), can END point initialize communication?
