@alextel69 I'm assuming you're referring to http://copter.ardupilot.com/wiki/mission-command-list/#do-set-relay?

[snorkel123]

@ne0fhyk Yes, exactly

@alextel69 sounds good. Are you looking to use it as part of a mission?
If so a MissionItem implementation should suffice similar to what was done for DO_SET_SERVO: https://github.com/DroidPlanner/3DRServices/blob/master/AidlLib/src/com/o3dr/services/android/lib/drone/mission/item/command/SetServo.java

@ne0fhyk I need both mission and nonmission control. I believe adding SetRelay is a better solution then creating the class in my app

@alextel69 SET_RELAY mission item support has been added in version 1.2.5.beta.

@ne0fhyk Amazing!
Only nonmission control left. Possible option is to get MavLink message from SetRelayImpl, then send it as a raw message. But it won't be a good design anyway. Waiting for command addition to drone class.

@alextel69 the nonmission SET_RELAY control was added in version 1.2.6.beta.

Given that function has no defined interaction model yet, it has been placed in the ExperimentalApi section of the client library: https://github.com/DroidPlanner/3DRServices/blob/87ea75bdd3aab4ac7a039e229686955158121261/ClientLib/mobile/src/main/java/com/o3dr/android/client/apis/drone/ExperimentalApi.java.

To make use of the new api, you'll need version 2.2.11 of the client library: https://bintray.com/fredia/maven/3dr-services-lib/2.2.11/view
