DJI Services Reply Mapping

The device returns command results through services_reply. The platform correlates the reply to command_id through tid and updates the command lifecycle. Clients do not consume the MQTT reply channel directly.
Open Platform fieldDJI services_reply source
response_codePrefer data.code; fall back to data.result when code is absent
response_messagedata.message / data.msg / data.description
vendor_responseNormalized DJI reply summary preserving result, code, message, output, and vendor extension fields
data.result = 0 means device-side execution succeeded. Non-zero values mean device-side execution failed, and the platform moves the command to a failed terminal state.
