Forgett my last message, I found what I miss.

I write this here for next people :

- Open nrfgo

- Select the board

- Erase the board

- On the right select Program SoftDevice and flash the right soft device HEX

- Again on the right select Program Application and flash the hex generated from program

It works

Again thank you for your time Jorgen.

I watched this documents, and I still have a question.

In my project I included nrf_sdh.c nrf_sdh_ble.c and nrf_sdh.soc.c

They are sources files about the soft device (they are in the folder components -> softdevice -> common.

My question is : Do I need something more about softdevice ? If yes i missed something.

Thanks four your help.

The softdevice is needed in all BLE or ANT applications. You can find some information about softdevices on this getting started page. The need for a softdevice is indicated on the top of the example documentation page. You can merge the softdevice with the application HEX file using our tool mergehex.

Thanks for your answer,

I dont know if i use softdevice, sorry nordic products are new for me. I have modify the ble_app_uart_pca100040_s132 project, if this can give you more information..

How can I merge the softdevice in my own HEX file ?

I tried to implant my HEX file by drag and drop and by using Target -> Download file

Hi,

Are you using a softdevice in your project? Note that projects for Segger Embedded Studio in SDK 14.1 and above are setup to flash the softdevice along with the application if needed. If you do not flash the softdevice together with your application, it will not work. The pre-build HEX files found in the example folders have the softdevice merged into the HEX file.

Best regards,
Jørgen
