UART0_IRQHandler not getting called in ble_app_uart

Aashish Patel

Hello,

I am trying to test ble_app_uart example code and replicate similar behaviour.

I have disabled hwfc. But without hwfc, UART0_IRQHandler is not getting called.

with hwfc it works fine.

does UART0_IRQHandler has any dependancy on hwfc

    I think I understood the reason. After debugging the code checking. It seems that UART0_IRQHandler does not have any dependancy on hwfc but on evaluation board PCA10001, nrf51822 uart is connected to segger uart and then to uart-usb chip ..so flow control would be required for comm between nrf51822 and segger.
