How to run nRF52 ble_app_uart code in segger embedded studio

[nikola]

Hello
I want to know what is the command that I must add  to the ble_uart code which exists in the SDK library to send hello word using the bleutooth in the nrf UART application .
Best regards.

It's not a single "command".

Have you got the example running as-is?

Have you studied the example as-is - to see how it's working?

[nikola]

I tried to study the example and know his functionality, I find a ble_nus_data_send function to send the data through bleuttoth, I want to send hello word on segger to test this code with the nrf uart application.

Hello,

Were you able to run the example before you started modifying it? Instructions on how you can test the original example can be found in the in the SDK documentation here: UART/Serial Port Emulation over BLE

when i do the build of the solution I  have got this error :

how can I solve it ?

[awneil]

It tells you where the other declaration is:

You need to make sure that the two match.

[nikola]

the other declaration is in stdio.h , it is not in the same file :

[nikola]

Should I delete it?

[awneil]

no - they need to match.

Your implementation (definition) needs to match the declaration.

This is basic C programming stuff.

It seems that you really need to go back to the original, unmodified example and get that working - as Vidar Berg suggested.

yess I already do the build of the project without any modification and I hhave got this error 

[awneil]

Something fundamentally wrong there, then - the SDK examples should build & work "out of the box".

Which SDK are you using?

Perhaps time to download a fresh copy, and start again?

I am using SDK version 17.0.2 and it didn't work so I decided to use another version and I tried with version 15.0.0 and it didn't work too
