We're trying to port the softuart library (https://github.com/plieningerweb/esp8266-software-uart) to use within the Sming framework, however, RX always gives out garbage. We've tried all sorts of baud rate but it doesn't seem to make much difference. Does this library interfere with Sming's interrupt architecture? Is there any way around this issue? We absolutely need to use some kind of software serial.

Thanks,
Alex
