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,

Hi ,

Thank you for answer

I want to receive debug tools data, and then transmit data to mobile phone through nRF52810 BLE.

Debug tools(UART Tx) ---> (UART Rx)nRF52810(BLE) ---> mobile phone

uart_event_handle should be a callback function

I don't understand , why does the system continue to enter this function ?

And then i use the debug tools to send data ,  but can not enter the callback function ?

===========================

nRF52810 send data to Debug tools is successful

SDK：nRF5_SDK_15.0.0_a53641a

example：ble_peripheral \ ble_app_uart
