Modbus protocol 00 00 vs 00 02

Is it possible to get the xarm to use 00 00 instead of 00 02 in the protocol section of the request?
Most TCPIP software uses the default 00 00 protocol (after the transaction id pair). It is supposed to be ignored under TCPIP but the xarm won’t respond unless the 00 02 is in that section. I know it says use 00 02 ‘for now’ in the developer manual but the only software I can find that has a feature to send a raw request is the Modbus Poll application using the ‘Test Center’ feature.

Hello, the communication protocol used by xArm is Modbus-TCP, so the currently supported protocol ID is only 00 02.
Thanks.

Heyo @My_Indoor_Farm

Are you still working on it? I was wondering how you used TCP communication to control different components.
