I played a lot with UART on Espruino based on STm32. Very handy to communicate with various sensors or external systems.
On STM32 boards SERIAL is very efficient thanks to the use of hardware peripherals in background. However, now that I am very convinced with Espruino on nRF52 (especially MDBT42Q which gives a lot of flexibility to build projects around), I struggle sometimes with the SERIAL library because it is implemented in software. I would say that with baudrate greater than 2400 Baud the Serial interface is not reliable anymore.
Is anyone experiencing the same limitation? Is there any plans to provide a better Serial on nRF52 boards?
