I have a payload device that normally uses Bluetooth LE to communicate to a phone app. Path of least resistance for operating and monitoring remotely would be via BLE. Ideally would like to develop a lightweight app that runs on the airside to log data. Are there any known BT dongles that would work with an OTG cable on the air unit?
I think it depends if the Bluetooth adaptor is controlled via libusb or the kernel.
If it’s libusb then it could be possible, but would require custom software to work.
