I’m using Zephyr to create a Bluetooth service, it all works fine but the device is not discoverable using an OS. The nRF connect app works and so does the python package bleak. I would like to know if anyone else has created and connected to a service and any reason why the OS rejects some BLE Advertisements. I have managed to get the sense microphone working over USB as a plug and play microphone and I want to do the same as Bluetooth audio.
Hi there,
So, Are you using the HID device LIB for it?
Check out the MIdi examples to get an example, sounds like your close so Stay with it, Post up the code and others can comment, Use the code tags above “</>” paste it in there.
You get better help and it’s easier to read and test.
