If you have one of the very early DX6R's, you may experience this issue. The first DX6R's had Bluetooth but not BLE drivers which is a different subset of the whole Bluetooth setup. We added BLE drivers as well along the way. We are talking about different ways folks can add in these drivers themselves but do not have this resolved at this time. So, if you are looking to have this update done, at this time, you would need to send your radio in. This update takes fairly extensive android knowledge.
