NUR AZLIN AIRUL AZLIN MOHAMED ZOHDI asked 2 months ago

Hi Rui,
I am using the LilyGo T-Call SIM800L tutorial. I need to connect my field device using a serial port. Since SerialMon is being use for debug, and SerialAT is for SIM800L, is there any more serial port left. If there is, please provide simple example to read from that port.
Thanks.
Nur.

Hi.
Yes, I think you can use a third port.
This video from Andreas Spiess explain that pretty well: https://youtu.be/GwShqW39jlE
