I am implementing a BLE connection between my pc and the Bangle js 2 to stream data from the Bangle to the pc and send back responses to the bangle. I successfully managed to connect the two devices (the bangle is acting as a server device streaming the data I need to a C# console), but I'd like to send back a response string. Data is wrapped in my C# and sent to the bangle but I cannot find a way to read it on the device: do I need to create a specific characteristic on my pc to which connect the bangle or am I missing something? Connection actually is successfull but is it biunivocal?
Thanks in advance!
