I am looking for Classic Bluetooth communication (RFCOMM)/ serial port communication using classic Bluetooth and not Bluetooth Low Energy(BLE) in Xamarin.Forms preferably. I have some emulator which is hosted on a com port and a Bluetooth adaptor. I want to connect to that Bluetooth adaptor and fetch/read data in my mobile app.
I had explored Bluetooth Low Energy(BLE) using ble.net plugin but I need to connect to a port i.e. Bluetooth SPP and read data in the mobile app.
There's no classic Bluetooth communication APIs in Xamarin.forms. You would have to use the UWP built-in Bluetooth RFCOMM APIs to communicate.
You could check the Bluetooth RFCOMM chat sample to learn how to use these APIs.
