i am using Keil Uvision5 ,,what is the sdk version you are using?

check you have included all the necessary driver files for the SAADC ,in the ble program

I am facing the same issue. I tried changing timer instance to 2 and 3 and is not working. BLE is not advertising if saadc initialization functions are called! I could see saadc values in PC using UART but BLE is not working.
what else you changed in code?
I use segger embedded studio.

thanks for the answer ,,,i found the issue and cleared it,,the code is working fine,,,

the issue i found is that ,with the softdevice Timer 0 instance will not work,,,

after changing the timer instances to other than 0 the code worked fine,,,

Did you try debugging the application to see if any functions are returning and error code that puts the device into the error handler?

You're in luck, we have an example for this on our GitHub.

Note that the SAADC samples are not converted to a strings before being sendt on BLE UART.
