RX / TX Ports usage

End-Of-Life Products & Services RePhone
#1

Hi there:
I’m trying to use my rephone to manage some external device using SMS’s; anyone has tried to use the RX / TX ports from the breakout; at the moment they seem to be in use at all times.
¿Are there any other pins i could use with Software.serial libraries or something like that to manage additional serial inputs?

Ty very much,
David.

Hello,

I think that they are used by Serial1 object in the Arduino IDE, but I haven’t tested it.
