Yes, I actually knew them all, Thanks for you help dear Martin, I tried precompiled application with the SoftDevice in the directory you mentioned and it works nice, So thanks again, but i can not load SoftDevice and main program separately. As i mentioned above So can you please help me to find out what going on when i try to load them separately, should i have to change the address of where program and SoftDevice load , to not to encounter the error : this file has data in SoftDevice region again? Or i have to update my software? However i think that they are up to date . Or it relates to the firmware of my j-link? Thanks for your attention.

Have you gone through the different links on how to program an application?

And i found out that there is another problem to, When I first flash the S130 SD on the nrf51822 and after that i try to flash the main program using Keil, an error occur that says failed to erase. failed to flash and when I tried using nRFgo studio doing that, the error : this file has data in SoftDevice region occurred. I was using the SDKv12.3 that you mentioned above.

Could it be caused because, I don't have DK and just nrf51822 itself? You know i connect the j-link to the device as the picture i have posted, and to connect device to computer by UART, I have set TXD pin, Pin 5 and RXD pin, Pin 6, as shown in picture (but a bit different, in picture TXD is 9 and RXD 11) but no other connection. for example for buttons or LEDs , etc ...

Hi Martin ,Thanks for you reply. but i have tried SDKv12.3 as you told me, but nothing changed, Am i doing something in wrong way? I am confused. I build blinky app and Uart_example and flash on my device and they run as they have to.

So they work on my nrf51822 but I can not run ble_app_uart on my device?

Hi Linosa,

I think you misunderstood something.

I recommend you to get SDKv12.3 since it supports do support nrf51822.

Please find the "ble_app_uart" project in [nRF5_SDK_12.3.0\examples\ble_peripheral\ble_app_uart\pca10028\s130\]

Compile and flash the application and flash the softdevice

You can also flash the precompiled application with the softdevice .hex file found in: [\nRF5_SDK_12.3.0\examples\ble_peripheral\ble_app_uart\hex]
