After the previous unsuccessful SDR scanning adventure, I’ve switched back to Bluetooth scanning with the nRF Connect app. It turns out that Droids have GATT services and are connectable when their paired remotes are off. The catch is that the app is disconnected almost immediately after connecting.
Below is the Services info found when scanning my droid. Of note, it looks like all droids have the same UUID numbers, so I’m hoping this is related to how the remotes communicate with them.
