Can you explain further?

Greetings

I need help to do what I think he wants to do.

I have 2 XBee 4G LTE modules and in addition to using the UART for passing data between at least 2 devices, possibly 3 or more, I want to take advantage of the Programmable I/O as either a backdoor or as control signals to enable or disable parts of the device.

With battery powered devices this can be advantageous.

I don’t see any information on the data structure of the XBee 4G LTE modules.

I at least understand that I will have to use API mode, and there are certain pins on the XBEE 4G LTE module that seem to be dedicated to certain functions, and I don’t want to interfere with that.

But I think there enough remaining I/O’s to accomplish what I need.

Can these I/O pins be configured to act as a data transfer channel between 2 XBee 4G LTE modules, the receiver acting simply as a mirror of the transmitter?

I think that should cover what I know I want to do.
