Nordic NRF 52 SDK 12.2.0 SDK , BLE is not working

[man]

Hello NRF ,

I am not able to run any of the  the BLE peripheral example codes from the SDK12.2.0 ( Nordic NRF 52 SDK )  .

The reason I am using 12.2.0 is I have a sensor SDK which is developed on 12.2.0 SDK and I need to add BLE services to read the sensor data over mobile application .

The sensor SDK is little complicated to port to newer version of nordic SDK , I am trying configuring BLE in the same SDK to save time .

Let me know for any clarification if needed .

Hello man,

I am not able to run any of the  the BLE peripheral example codes from the SDK12.2.0 ( Nordic NRF 52 SDK )  .

Have you flashed the softdevice before flashing the application? All the BLE applications need the Softdevice (BLE stack) else your applications won't start. It is OK to use an older SDK to save time and for compatibility reasons. What do you mean by "not able to run any of the BLE peripheral examples". They should run if you are using the same hip versions as mentioned in the release notes here. Which example are you running? and what is the device laser marking you have on your chip? Are you sure you have selected the correct project to suit the chip family?

What happens if you run the example in debug mode?

-> nordic_sdk_12_2_0\examples\ble_peripheral\experimental_ble_app_blinky\pca10040\s132\arm5_no_packs

-> I am using Nordic nRF5-DK board ( PCA10040 - NRF52832)

 You need to flash nordic_sdk_12_2_0\examples\components\softdevice\s132\hex\s132_xxxx.hex file in your device for ANY BLE app to work with nRF5 SDK.

You can go to command prompt and go to the directory into which this hex file exists and type below command

nrfjprog --program s132_nrf52_3.0.0_softdevice.hex -f nrf52 --sectorerase -r

You application should work after that.

It worked , thanks .
