BB.Error.Protocol.Ufactory.CommandRejected exception (bb_ufactory v0.1.0)

Raised when the xArm returns a non-zero status byte in a command response.

The UFactory Modbus-TCP response frame (port 502) has the format:

[Transaction ID: u16 BE] [Protocol: u16 BE] [Length: u16 BE]
[Register: u8] [Status: u8] [Params: binary]

A status of 0x00 means success. Any non-zero status means the arm rejected or failed to execute the command. See the xArm Developer Manual V1.10.0, section 2.1.5 for the full status byte table.

Note: The controller currently operates in fire-and-forget mode and does not read back command responses. This error type is provided for use when synchronous response handling is added (e.g. for gripper position confirmation or F/T sensor enable acknowledgement).
