Can you be more specific please?, I am not quite getting the question.

Abbad-Zafar commented 3 years ago

I want the hex response or packet which the master sends to slave or vice versa

I would like to know how to read the complete message including reading the unit id

dhoomakethu commented 3 years ago

@Abbad-Zafar there is no direct way at present to get raw response. You may have to reverse engineer the registers to get the frame.

Abbad-Zafar commented 3 years ago

@dhoomakethu Doesn't the logging show info about packets ? What are being sent and what are being received ?

dhoomakethu commented 3 years ago

You can view the data if you running with level debug.

A spin out RFE for Serial would be to use serial.serial_for_url() instead of serial.Serial() to allow the spy:// url schema to be used.
