I have modified it slightly to add the waitFor the USB serial, and also to test for the MAC address every boot. Since I'm using the default pins, I set the pin-remap to PIN_INVALID as noted in the docs. I also removed the retained memory bit since it ties 3 times, fails to remap, then never tries again.
Heres the extent of the output:

Can I expect the Photon 2 to get the MAC address from the module without being connected to a network? I am connected to a switch and activity lights are flashing on the Adafruit device, but unsure what conclusions can be drawn from that.
Here's the breadboard setup to show that it's pretty bare bones.
Appreciate any sanity check on this!
Going to try to use the adafruit lib that only uses bare SPI. If I can get that talking then it must be something with the RST/IRQ pins.
