Hi
I managed to download the bin file under \BinFiles\BinFiles_B2_v40 from ISP
But after I download the keil built bin file from ISP or directly download from keil(using code under \Projects\BLE), the board isn't working properly, leds off and no response pushing the buttons.
Solved! Go to Solution.
Hello,
Could you please help me confirm you are using Bluetooth LE version 4.2? You will need to be sure to be using the qn9020b4_lib_peripheral_v42.a library

I think I have correctly set the options in keil, but the board still failed to work properly.
Hello,
Could you please provide more details on which example are you using ? Are you using the low power capabilities ?

The broadcaster example. I didn't change the code.

I repaired the SDK and finally solved the problem.
Thanks a lot.
Under QN902x_SDK_1.4.0\Projects\BLE\src\lib, I can only find qn9020b0_lib_peripheral,qn9020b1_lib_peripheral and qn9020b2_lib_peripheral for keil and IAR.
