[W-MBUS]”We have a board for Wireless M-Bus which is connected one of the UARTs at the Arm Cortex A5 which we are using. Now we have had some units which have stopped working. We got one to the office last week and this one seems not work at all. We could not send the configuration commands etc. “

If devices work at startup, but after a while all UART ocmmunication stop to function, then our first suspision is always that customer has un-intended entered config mode and changed configuration.
