- [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] “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 ? “
