What does app_uart_put() return? (what is err_code after this line is executed?)

And are you aware that when you are using:

err_code = app_uart_put(wfcr[wifi_tx_idx]);

you are only sending one byte?

Look at how the ble_app_uart example is using app_uart_put inside a for loop to print an entire message.

Hello,

[quote userid="26071" url="~/f/nordic-q-a/83407/communicate-wifi-with-customboard-nrf52833-through-uart/346515#346515"]If you try to connect the UART pins to a UART terminal, do you see any data there? What do you expect to see on the nRFs TX pin?[/quote]

I didn't check UART terminal yet, but I want to communicate with wifi module over at commands.

// wfcr[] = 'AT\r\n';
err_code = app_uart_put(wfcr[wifi_tx_idx]);

so I send basic command ( 'AT' data ) for test using 'app_uart_put'. (I followed 'ble_app_uart' example.)

briefly, I want to send the at command, but it seems to be confirmed on the RX pin, not the TX pin. If it's not a hardware error, I want to know what kind of error it is.

You are using custom HW, right?

What log backend do you use? (it should say in your sdk_config.h file).

yes,

I'm not fully understand what log backend is.. but as I checked sdk_config.h file, these definition set bit.

#ifndef NRF_CLI_LOG_BACKEND
#define NRF_CLI_LOG_BACKEND 1
#endif

#ifndef NRF_LOG_BACKEND_RTT_ENABLED
#define NRF_LOG_BACKEND_RTT_ENABLED 1
#endif

Hello,

If you try to connect the UART pins to a UART terminal, do you see any data there? What do you expect to see on the nRFs TX pin?
