I can send DATA by libuarte but i can not receive

Hello ,

I'm using the libuarte library so i can send data and receive it , i'm enabling RTC2,TIMER1,TIMER0 and TIMER2 .

this is the main definition of my libuarte NRF_LIBUARTE_ASYNC_DEFINE(libuarte, 0, 0, 2, NRF_LIBUARTE_PERIPHERAL_NOT_USED, 255, 3).

the problem is that i can transmit DATA but i can not receive (because no NRF_LIBUARTE_ASYNC_EVT_RX_DATA event was generated when receiving) 

i tried a lot of combination but none of them has worked.

in the hardware part i've visulazed the transmitted DATA by OSCILLOSCOPE,

And then in order to test the receiving i did a loopback (TX to RX directly), but no NRF_LIBUARTE_ASYNC_EVT_RX_DATA event has been generated till now .

I ve read other threads that are talking about this topic, i ve tried their solutions but that didn't work for me.
