I recently acquired a Labradar and planned on using one of my Samsung devices for remote control. The bluetooth worked ok at first, an occasional disconnect from the unit 2 feet away from the Labradar but today it quit working entirely. I have tried on 2 Samsung phones and a Samsung Tab A and cannot connect. The devices see the Labradar and even pair with it but I keep getting "communications error" when attempting to connect. So far the best I have gotten from Labradar CS is Samsungs have bluetooth issues and reset the communications on the devices. I did that on the phone w/o a sim card that I normally use for drone flying and did not cure the problem. Also reinstalled the software, reset the Labradar to factory settings etc and it refuses to connect. I re emailed them but it's a small company so I am pretty sure they closed shop a few minutes after they emailed me and went home. Hopefully I will get a response Monday as to what else we can try, if anything I have connected my Samsung devices to drones, external speakers, my audio system as well as to each other and never had issues. Anyone else have a Samsung and a Labradar and figure out how to get them to work together reliably ?
