Sending data received with BLE scanner to esp32 with uart

[sasci]

Hi everyone. I want to take advertising data with ble scanner and transmit to esp32 via uart. But I don't know how to do this. Is there an example for this? I need your help on this.

Hi Karl,

I have a problem. I worked hard on this subject but every time i got error on app_uart_put(). I can't send data with app_uart_put() but when I use printf() I can read data from esp32. Which is correct for uart? And why?

What error do you get when you try to use app_uart_put?
printf prints on UART if RETARGET_ENABLED is defined to 1 in the sdk_config.h.

Best regards,

When I use app_uart_put(), don't read received data. But I can read that on J-link RTT.

Specifically which error does the function return?
Please make sure to have DEBUG defined in your preprocessor defines like shown in the included image:

This will make your logger output a detailed error message whenever a non-NRF_SUCCESS error code is passed to an APP_ERROR_CHECK.

If you have configured the logger to use the RTT backend you will see the NRF_LOG_* statements printed to RTT. The RTT terminal does not output UART messages.
