BLE application problem

[rt-true]

Hello!

I bought NFR52 DK preview board. As microcontroller it works well. But when I try BLE examples, they do not work. I installed SoftDevice S132, downloaded ble_app_uart_s132_pca10036 example in Keil and launched "nRF Toolbox" application from playmarket. BLE in mobile phone is supported, but I can't find nRF52 DK board in application.

When I launched debugging in Keil, program stopped on this line: SOFTDEVICE_HANDLER_INIT(NRF_CLOCK_LFCLKSRC_XTAL_20_PPM, NULL); I can't find solution of this problem in internet.

Can you provide BLE working example or BLE beginners guide or detailed manual how to set up Keil or make it all work with BLE.

Thanks.

Hi

To start with, make sure you have the correct software components for the hardware that you have, by looking in the nRF52 compatibility matrix. For the preview nRF52-DK kit (PCA10036), you should use the S132 1.0.0-3.alpha and nRF52 SDK 0.9.2.

Procedure:

1. Open nRFgo Studio and press "Erase All"
2. Select the "program softdevice" tab, browse to S132 1.0.0-3.alpha hex file and program it to the nRF52-DK
3. Open example in nRF52 SDK 0.9.2 in Keil, compile it and flash it to the nRF52-DK, e.g. ble_app_hrs example
