Hi Muqarrab, 

Please step in the code of nrf_libuarte_async_init and check which exact function that return the error ? 
I saw that in your previous case back in December last year you managed to use libuarte with your app already, so what make this different ? 

[Muqarrab]

Actually, it's another project 
I have followed the same steps but getting this issue.

Please step into the code and debug. 
Error 0 means success so I don't see it as an error. 

[Muqarrab]

I am debugging and getting the following error.

Have you tried to step into the code of nrf_libuarte_async_enable() ? We can't help you if you don't try to do any debugging. 

You would need to set a breakpoint inside the function and step by step check what causes the assert. The code is not a black box. 

Please double check if you have declare the module with NRF_LIBUARTE_ASYNC_DEFINE() and call nrf_libuarte_async_init() prior to nrf_libuarte_async_enable()
