Hi,

is possible to use auto baud detection for Modbus RTU slave?

Something like this: https://gist.github.com/tuxmartin/46ca107057c650fbe6f63dcae5ee067d

My idea:

Modbus Master (Raspberry Pi) set serial port speed to X.
? (Modbus Master send broadcast message for synchronization every X seconds.) ?
Modbus Slave (Arduino) run detection of speed every X seconds.
Modbus Master periodically read data from all slaves - if any of slaves do not respond, slow down serial speed.

Thanks.
