Benewake TF mini-I can

Good morning Ardupilot,hope every one is well and having fun.

I am at loggerheads with my Benewake TF mini-I-can,I have got it working great on my cube orange with latest dev firmware,my proplem is I cannot get it to connect to the Benewake GUI using the tx and rx wires,no mater what I try,bloody thing it is,I only want to change address from 3 to 4.

I have a Benewake TF03 uart/can and it is a dream to work with it is runing on serial and connects no problem to the GUI.

The reason for wanting to change the address is to use a number of the TF mini-I-cans for object avoidance.

Many thanks in advance and have I nice day,love from bonnie Scotland
