I have been using Bluetooth Serial Port (BSP) at
/dev/tty.**** successfully in the past in order to communicate between macOS Big Sur (11.3.1, M1 processor) and Android (8.1).
However, when I want to connect my Android device to a new computer, pairing works but macOS almost never creates the
/dev/tty.**** device which makes the setup of a new machine very random. I noticed that the bluetooth device stays not-connected; if I force-connect it it connects for a few second then goes back to "not connected".
Files sharing works as well: in this case the bluetooth connects, the file transfers, then the bluetooth disconnects. And still I never see the tty device.
My question is:
- is there some configuration needed to be done on macOS or Android side to get the tty device?
- is there any other solution or tool I could use to communicate via Bluetooth with Android that does not depend on tty. I'm thinking for example a way to connect via MAC address, and send/receive data the same way I use the serial port
- the same tablet connects to Linux and Windows, but I need to use macOS.
- the same issue occurs with Fire OS 220.127.116.11 on Android side, as well as macOS Mojave (10.14.6) with an Intel processor.
- I currently use Python to read/write to the BSP, but I can use any command line tool / language in the middle (as long as it works with macOS Big Sur with a M1 processor)
