nrf52832 example issue with sd_softdevice_enable function

[david.gutierrez]

Hi,

I just got a nrf52832 pca10040 board and I downloaded the last SDK nRF5 v11. I downloaded Keil uVision5 and was able to load some examples and test them: nfc record_url, blinky_freertos... I want to use BLE capabilities of the chip (not ANT), so I loaded softdevice 132 from nRF52_SDK_0.9 using nrfGo Studio. I wanted to use the new SDK one, but the 132 folder is empty.

I opened experimental_ble_app_blinky/s132/arm5_no_packs example. I compiled it with no issues: 0 warnings, 0 errors. I was able to load it but the board made nothing. I then debugged it and I found it was getting got stuck in * sd_softdevice_enable* call in line 285 of softdevice_handler.c. The call stack ends in ble_stack_init(), which is the 4th instruction in main. I tried to go to the definition of the function but the IDE tells me that there is no reference for this function, however it compiles with no problem... ¿?

I have the board as it comes from the distributor, so I guess hte problem has something to do with the configuration, or something I have done wrong...

Also, I found something strange in Keil. In the project view I see the Device branch with an error symbol, but it compiles ok and I can open both .s files.

Can anyone tell me why the example code does not run?

What do you think I could have possibly done wrong?

Thanks!

I bet you don't have softdevice flashed on board. Download zip with latest SDK, don't use s132 from old sdk.

Erase chip and flash proper SD (ex. using nRFgo Studio) located in here:

nRF5_SDK_11.0.0_89a8197\components\softdevice\s132\hex\s132_nrf52_2.0.0_softdevice.hex

Hi,

You must download both application and SoftDevice. You can do both from Keil, by choosing from this drop-down on the toolbar:

Thanks both Terje and Wojtek.

Somehow the SK zip did not unzip correctly and I saw the softdevice132 folder structure correct but with no files in it. I assumed I had to use the older one. I downloaded it again and with the 132 softdevice correctly downloaded everything works great!
