Yes, you must force RX mode before using the ‘s’ command.

- [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] “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 ? “
