I have a Photon that needs to be connected to two serial sensors. As the Photon only has one serial port (actually two but the other is used by the LED), I have used in the past the SoftSerial library which worked well.
However, I have a serial sensor that is giving wrong results with the SoftSerial library.
What could the reason be? (Sensor is using 115200 baud but can use a lower speed).
Is there an easy way to add more UARTs to the Photon?
Thanks in advance for any help.
