[W-MBUS] What happens if there are two MBUS masters in the range of a slave?

If both Masters are configured to accept all messages they will both receiver the same message from the slaves. Note however that the installation feature in RC1180-MBUS2 to bind slaves to a master. If you do this you can change the Master mode to only accept installed slaves. This is described in details in the MBUS User Manual.

  • [W-MBUS] Does your device support both AES-CRT and AES-CBC. If it does do I have to make any special setting to choose either of them or will RC1180 automaticly decode the data using the information how to decrypt the packet using the MBUS status-byte? “
  • [W-MBUS] Does MBUS3 or MBUS4 support over-the-air FW download (OAD)?
  • [W-MBUS] “we have a problem with the configuration of RC1700HP(MBUS4). We start our micro and we start the comunicacion for the uart with the radiocraft RC1700HP likewise with the RC1180 MBUS3 (with a low level in the nConfig pin) but the Radiocraft RC1700HP don’t responde (with the symbol >). We watch with the oscilloscope that in the pin RTS/SLEEP in this case we have a High level and in the RC1180 we have a low level, could be this the problem, you know why can be? The supply that we use for the RC1700HP is Vcc = 2.5v and Vcc_PA = 3.6v. Is this ok? “
