I don't think like I'm able to help - lack of knowledge and other tasks to do. I suggest you to open a new thread with this problem so Nordic support team can assign you an engineer. This thread is already marked as "solved".

Hi,

My setup is completely the same as yours. I tried to run the UART example then bidirectional communication is possible as because I could send and receive data through TERMITE.

I added the UART example to another example but in that case, I just can see the sent data from my phone to nRF52840 board but I can't see the data sent from my nRF52840 board to my phone.

Can you please help me with the problem???

Update 2:

Bidirectional communication in ble_app_uart works as I believe it is supposed to, I can send and receive data using a terminal. I just had to use TERMITE, because puTTY and J-Link terminal weren't suitable.

So for now it is solved

Update 1:

It looks like the tx buffer comes empty, despite I put some random numbers into RX Characteristic in the mobile app.

void uart_event_handle(app_uart_evt_t * p_event)
{
    switch (p_event->evt_type)
    {
        case APP_UART_TX_EMPTY:
            NRF_LOG_INFO("quite empty, isn't it?");
            break;
            
    }
}

it prints "quite empty, isn't it?" on the terminal :(
