[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)?

For security reason there is no command to read the internal encryption key.

    • [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] “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. “
