- [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 ? “
- [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] “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 ? “
