Can anyone here recommend a bluetooth keyboard with built-in touchpad that will work with the Pinephone's internal bluetooth (that is, without requiring its own dedicated USB receiver)? Hooking up a mouse and keyboard via the dock works but it's pretty awkward to work with the phone that way.
I've only tried it a while back with an ancient iGo Stowaway - no problems there, as expected since it used to work with the old OpenMoko. That's a classic bluetooth keyboard rather than a BLE one though, and doesn't have a touchpad, so may not be indicative of compatibility with more modern devices.
If the trackpad is anything like the one on the Rii mini i8 (not bluetooth but similarly small) it will be frustrating to use - a trackpoint would be much better, or a larger touch surface on the back of the keyboard. Not sure if anyone makes one with either of those though. Being Bluetooth 3.0 it should be fine so long as they've not gone for nonstandard quirks.
That's good to know - it might be a decent replacement for the Rii.
