UART DATA FLOW CONTROL

[Darshansm5549]

Hello,

I am using nrf52832 development board. I am using segger tool. In example -> ble_uart , i am sending some 100kb of data to UART using BLE. I want to controle the flow like, i need to add one button, if i press the button the flow of data to UART need to pause. when i release the button the flow need to continue(withoyt losing any data) . how to implement that?? please help me.

thank you in advance.

You need to find whatever function is calling 

ble_nus_data_send and prevent it from doing so.

Use the button library to control that functionality.

I tried that, uart_event_handler is calling ble_nus_data_send. it is not working for me... Can you provide me any other solution??

"it is not working for me..."

I need more information on why this is not the solution you need.
