Could you share your experience regarding the possibility of cooperation between the adrucoper and the power supply through the generator. I mean the possibility of transmitting telemetry (voltage, current, status, etc.) or controlling the generator itself. The documentation shows that there should be GEN_TYPE parameters, but they is not in version 4.0.7. There is possible parameter to be displayed in telemetry (gen_xx) so something was done on this topic in the code. You can also set BATT_MON to Generator.
OK. Copter-4.1.0 is in beta testing and can be downloaded using MP or QGC’s beta firmwares link (or button) on the install firmware page. In 4.1.0-betaX you should find a GEN_TYPE parameter.
