I have built two Telemetry sensor stations base on Arduino Pro Mini board that gives me one RPM, one Temp, all gps data, and voltage and current on the transmitter display.
I also added total current used (displayed in RPM 2 field on the transmitter).
My question here is, I have been modifying the code to use the MavLink messages to display GPS, I also wanted to display the flight mode in Temp3 display, current waypoint in Temp2.
I decode WAYPOINT_CURRENT (#42) but it only changes just as the waypoint changes, the rest of the time it is 0. Is there a message that gives the current waypoint all the time?
Next SYSTEM_TIME_UTC (#4) message doesn't seem to go off at all. Is there a way to get this message sent from the APM.
