void nrf_cli_print_stream(void const * p_user_ctx, char const * p_data, size_t data_len)
{
    cli_write((nrf_cli_t const *)p_user_ctx,
              p_data,
              data_len,
              NULL);
}

I think I just answer my question already Just rewrite this function and send 0x?? into a char[] to the buffer and send

Vidar Berg i would like to know is there a function to send message directly without readable message and in binary format in uart

It sounds like something you can use the UART driver for. It's not clear to me why you need to use this with this interactive example, and why you are trying to use the same UART HW for CLI and this custom protocol you have.

honestly i need to rewrite some specific protocol to connect to the device i know in some sort of timing the uart will send the message which is unreadable to the target and make it readerable i was wondering which function are those Vidar Berg

[quote user=""]the reason why om doing this is because i want to set the uart rx by myself to connect other device [/quote]

Do you have to use the same pins/UARTE for this, or would it be an option to use the second UARTE instance with another RX pin? You can use the UART driver to set it up.

nah my ble is running but what i want is make the uart rx output in specific devices in my company which i need the buffer and uart rx function

i want to find the function which put all the character into a buffer before it output to the uart

also want to know when did the code call the Uart I only found

[/quote]

I find the easiest way to find such things is by stepping in the debugger.

You should be able to set a breakpoint on writing to the buffer.

Easier to do when BLE is not running - otherwise you'll need Monitor Mode Debugging:
