I'm very urgent ， When PC sends UART data, nRF52810 cannot enter a callback

[tony55723]

The production line is waiting ， I'm sorry to ask that it's urgent

This debug tools display nRF52810 UART Tx is Successful

If I add the code

case APP_UART_TX_EMPTY:
printf("\r\nTest.\r\n"); 
break;

Then the debug tools will continue to print "Test"

This callback function is entered, but I want to receive data before entering.

Thanks all

Hi,

 

If I add the code

case APP_UART_TX_EMPTY:
printf("\r\nTest.\r\n"); 
break;

Then the debug tools will continue to print "Test"

This callback function is entered, but I want to receive data before entering.

 

This code will continuously print "Test", as you are pushing data in a event that is signalling when the buffer is empty. What do you really want to do here?

Could you explain a bit more in detail?

 

Best regards,

Håkon

Thank you , my problem has been solved

It should be 【P0.07 -> Number 7】, not order of arrangement（nRF52810 have pin 32）
