QN9020 fail to download

[Doomer]

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.

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.

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 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.
