RE: nrf52840 Hardware flow control query

Thanks Siguard,

In my case i was exploring Half UART (Only Tx, Rx) just because my particular hardware has some issues with the RTS, CTS pins.

I learnt that using full uart also covers worst case scenarios. So full UART (Tx, Rx, RTS, CTS) is the robust and recommended way for the UART communication between two devices.

Thanks,

Mayank

I recommend using UART with flow-control. With flow control you don’t risk losing any data(buffer overrun), if one of the devices need to do some processing, and is therefore at some point not able to receive all the data being sent.
