Maybe your app is sending the data too fast for app uart to keep up? In that case, it should help to increase baudrate if it's an option.

sorry. I check with nRF Uart app, its working.

i check with my own designed app, that time only this kind of error is coming.

The default buffer sizes should be sufficient. Are you able to receive the UART TX data on your PC?

also my buffer size is mentioned here...

#define UART_TX_BUF_SIZE 256 /**< UART TX buffer size. */
#define UART_RX_BUF_SIZE 256 /**< UART RX buffer size. */

Hi,

After debugging, the error code is read from

err_code = app_uart_put(p_evt->params.rx_data.p_data[i]);

so, how can i resolve this problem.

Thanks and Regards

Hi,

Please confirm if the no memory error is returned from app_uart_put(). The error is returned from this function if you have run out out of TX buffers in the app uart library.
