I'm having trouble connecting my own Android app via BLE to the QN9080DK board.
Using the NXP IoT Toolbox app I am able to connect the DK board using the UART interface but I couldn’t find the way by using Android BLE examples or using a UART Terminal app after trying several other approaches (including a laptop application using the BLE Microsoft terminal). In all cases, I’m always getting BLE Status 19 error.
I have been investigating your communities but I haven’t found any useful solution.
So I wander if you can provide me the code you use for BLE communication or can you guide me on what might be causing the error? In the past we used BLE modules from other vendors (Nordic, NXP, etc.) and we never found such troubles, since we can start from their app source code to build ours.
