My apologies if this have been posted/discussed before. I have scrolled through posts back to July but not found anything on topic. My P2V+ took a bath. I cleaned it up and got it back to life, but after self-test procedure I get continuous quick flashing lights ("Transmitter Signal Lost") What works: - Camera + Gimball works; also video link to Android phone. - Tx checks out fine in "DJI RC System Assistant" software (v 1.1) - Tx binds to Rx just fine. Binding process works as it should. - P2V+ connects to P2V+ Assistant software (v 3.2) and firmware upgrade to v. 3.06 What does not work: - No ability to calibrate Tx through P2V+ Assistant software. I get CFG-ERR ("Configuration error, this may cause by firmware upgrade from old version.or abnormal Tx calibration. Re-calibrate your transmitter,and power cycle your controller and check all of the parameters." What I have tried: - Replaced Rx unit = no change to behavior - Replaced main controller (Orange box) = no change to behavior - Replaced all cables Anyone have any tips of what to try next? Could it have something to do with my firmware upgrade? I have attached a screenshot of my versions page. Thanks in advance.
