I see that the NRF52DK has a second UART defined as a "bit-bang" UART. As I've said earlier, I'm working on the air_quality demo, and part of that is moving it over to the NRF52DK board from the STM32F3-Discovery board. I'm doing is because a) the discovery board doesn't have bluetooth or any other network connectivity and the NRF52DK does and b) Support for the STM32F3 board is lagging and having this demo updated is important.
That being said, is the bit-bang UART going to be fast enough to support the SenseAir sensor's needs? In reading up on the NRF52, it seems that I could also define another set of pins as a UART (https://devzone.nordicsemi.com/question/70755/nrf52-uart-pins/ <https://devzone.nordicsemi.com/question/70755/nrf52-uart-pins/>) but if I don't need to do this, and can just use the bit-bang UART, that gets me there.
