How is General Purpose IO line pass turned on? Or associated bit to bit?

Yes, I suppose “General Purpose IO line pass” is what I’m asking about, but the question is . . . what AT command turns it on/off, and what associates which Dn on the input to a Dn on the output? Or . . . is it always on in 802.15.4 devices and always same=same on which Dn is mapped to which Dn? There are examples here and here But neither of them (or anywhere else I can find) explain what triggers the association from side to side. Or . . . is it just always on?


It walks you through the configuration.

It is the Addressing you use along with which lines you use. That is to say, DIO 0 on module one will go to DIO 0 on module 2.
