(that's the magic in: WL1835MOD_INI_C2PC.ini)

We are using the same wl18xx-conf.bin firmware for:

Original CircuitCo (now out of production) wl1835mod cape for BeagleBone Black
updated GateWay Cape from embest (this was meant to replace the wl1835mod cape)

SeeedStudio BeagleBone Green Wireless
BeagleBone Black Wireless

and the upcoming: (jason just sent me the next alpha, so i'll have a
patch after i verify all changes..)
BeagleBone Blue

For FCC testing, this was the same firmware (wl18xx-conf.bin) that
SeeedStudio used when they did the official FCC testing on the Green
Wireless.  I believe GHI Electronics did the same with the BeagleBone
Black Wireless, but i wasn't CC'ed in that email conversation, so i
can't say with 100% certainty..
