Hello,

First of all, I apologize for my poor English

I have a problem concerning the communication between two XBee Pro S3B. Indeed, I manage to establish the communication with the XCTU software, however when I try to light an LED using a communication between the two modules, it does not work. Can I have some help, please.

Are you trying to perform DIO line passing?

I’m trying to switch on a LED with a potentiometer between two XBee but i don’t have a Shield. It’s a problem ?
