Properties
Custom binary command
Examples
custom_binary
Send custom command to device, message type 0x33. Note! This command is applicable to Maxtrack binary protocol devices, not protobuf!
payload: Parameter value. Variable length. Depends on parameter_id
parameter_id: HEX representation of number that defines which parameter to change
Custom protobuf command
custom_protobuf
Send custom command to device. Note! This command is applicable to Maxtrack PROTOBUF devices, not binary!
payload: Payload data. Variable length. Depends on message_type. Must be protobuf encoded HEX
message_code: Message type HEX formatted. Refer to Maxtrack protobuf specification
