Changing NRF_FLOW_CTRL pin(P0_14) found not pulse

Post by Person »

Hi,
I have changed NRF_FLOW_CTRL pin(nrf51822 is P0_14 pin and stm32F4 is PA4) to new connection(nrf51822 is P0_08 pin and stm32F4 is PC15) in my own PCB. I also changed the pin init of NRF_FLOW_CTRL in stm32 and NRF firmware. I think is ok but the pulse of NRF_FLOW_CTRL pin when connected to the client is vanished not as to old quadcopter have a timing pulse. I didn't find any code about the pulse of NRF_FLOW_CTRL pin but it indeed have a pulse in crazyflie.I am confused and can you tell me where can I find the codes about this.

This pin is configured as hardware flow control in the NRF51, so it is configured by the UART driver.
