QN9090-DK006 Wireless UART example design

[blas_m]

hello there,

I am trying to get working the example design (wireless uart bmp) from the MCUExpresso IDE for the QN9090DK6 platform.
1st) imported example design
2nd) Build design without visible Errors or warnings( Attached compiled output file)
3rd) Click "Debug" and the design halts at the OSA_Init() call
4th) Click "Run" -> no flashing LEDs on the board indicating the device is advertising, the device is not seen on phone BLE app
5th) Press "User Interface" (BP1) button on the QN9090DK6 Dev board -> no flashing LEDs on the board indicating the device is advertising, the device is not seen on phone BLE app
7th) Terminate Debugging Session -> no flashing LEDs on the board indicating the device is advertising, the device is not seen on phone BLE app

What I am missing on those steps to see the example design advertise on the phone BLE app?
I have tried other example designs like: Heart rate monitor and I can see the device advertising and liste on the phone. That example also allows to connect to the BLE device and read valaues

Hello,

Hope you are doing well. What SDK are you using? Did you modify the SDK example?

Could you please help me checking the "Bluetooth® Low Energy Demo Applications User’s Guide"?

The Wireless UART example starts as a GAP central. If you press the USERINTERFACE button, the device will start Scanning. To change to GAP peripheral, you would need to press the role switch (ISP button).

Hope this helps.

Regards,

Ricardo

Thank you Ricardo for giving some debug suggestions and asking about this problem.
I have managed to get the example design working for the UART after following your indications about the buttons selection:
- 1st) ISP button to switch between Central and Periferal device so that the QN9090 board becomes a Server module 
- 2nd) USERINTERFACE button, the device will start Scanning so that I can find it using the IoT ToolBox

it was useful to open the Debug terminal (COM_XX) where the Debug program prints out the status of the BLE module
Just a quick question, how could I connect to the board using the GAP Central?
