Two serial ports

[osiriust410]

Hi,
I'm using two serial ports, in this library I was looking for the Serial.listen() function or similar, but I can not find it. Please help me, or tell me how I add this function.
Thank you.

Hi,

What do you mean by "using two serials ports" ? You can pass the Serial instance you want to use to the SIM808 constructor, so you're free to call listen() on your instance at your convenience.

For instance, that's exactly what i'm doing when I put my gps tracker to sleep to prevent an interrupt on one of the serial pins to woke up the device.
