nRF52840 DK:

ble_app_blinky is working. After that, I flash ble_app_bms, ( working),

then flash ble_app_blinky- the smart phone is not able to discover service .

Any idea ?

everything is done with Seggger embedded Studio. (Before flashing, I also did erase)

Thanks

Hi, 

Could you use nRF-Connect-for-desktop -Programmer or nRF-Command-Line-Tools with the following commands for nRF52-DK?

nrfjprog --family NRF52 --program s132_nrf52_7.0.1_softdevice.hex --chiperase --verify

nrfjprog --family NRF52 --program ble_app_blinky_pca10040_s132.hex --sectorerase --verify

nrfjprog --family NRF52 --reset

s132_nrf52_7.0.1_softdevice.hex  is under nRF5_SDK_16.0.0_98a08e2\components\softdevice\s132\hex

ble_app_blinky_pca10040_s132.hex is under nRF5_SDK_16.0.0_98a08e2\examples\ble_peripheral\ble_app_blinky\hex

Please also refer to the BLE Blinky Application section for the setting.

Hello:

I am new to the tools. I am not familiar with- the nRF-Connect for desk top-Programmer, NRFgo and  nRF command line tool.

I am using S140. I Can work with Segger IDE.

From you comment , I did S140  hex programming , after that , I did blinking app ( from component folder ) programming -all with Segger embedded Studio. ( Segger IDE-Targer-download file) 

It works!

According to Segger's doc,  if we use the Segger  examples, then we should not do this separately.?

Furthermore, with Segger IDE, I build the blinking example project-which generate HEX ( in Release-EXE folder)  , I then programmed this released HEX. ( Segger IDE-Targer-download file)

However, 

It does not work.

I found the fresh build application hex in Release-EXE folder   is different from the one in  component folder.

Could you explain ? What should I do ?

Thanks a lot!

sorry, the standard application app is from example-hex folder, not from component folder.

Thanks

Hi ACAMP, 

The application has to work with softdevice.  Please see the BLE Blinky Application documentation: 

Important: Before you run this example, make sure to program the SoftDevice. 

You could start the Segger project under nRF5_SDK\examples\ble_peripheral\ble_app_blinky\pca10056\s140\ses. In the segger project, it will also load the softdevice image (in the project option -> Loader) when it flashes the application image.

You should use Build and Run/Build and Debug or Go. Please see SEGGER Embedded studio – Getting started
