Today was the first time I lost connection to the Spark and fortunately, I had set RTH as the mode to automatically start if the signal was lost. It was a relief to hear it overhead and it descended to eye level, hovered, and I grabbed it and turned it over to shut the motors down.
I can't understand why the connection was lost because I was in flat countryside and LOS was as good as it gets. I had seen a lake in the distance and was flying towards it when I realised that the battery was down to 50% and I don't like to take risks, so I pressed RTH. Then suddenly, the connection was gone and I was really worried. I figured it would still be somewhere up there as there was still battery and hoped it would RTH automatically. It had been about 400 metres/1,300 ft away from Home Point and 1,500 ft/456 metres up. We don't have restrictions here and I was in a very open area that is away from any airways.
I do get occasional weak video transmission messages but they come and go and I believe they do not affect the control connection. I also watch the signal strength indicator and it was 3 bars at the furthest point. The flight data doesn't seem to show any lapse from takeoff to landing so nothing to learn from there. I could download the flight log to look but for now, I am not doing so. I came home and sent the Spark up again to check if anything would happen but it flew ok.
I am just wondering, for those who have lost connection and managed to reconnect, what did you do? I tried to switch the RC off and then back on, restarted my tablet and GO4 and nothing worked. I have once lost a connection with my Mavic Pro but managed to reconnect by restarting everything.
