[SOLVED] Strange PowerNap/SMBIOS(Board-ID)/Airport behavior

[kusakata]

Alright just for completeness sake, and to officially mark this solved, thought I'd wait a bit before reporting back.
So, for the last 10 days since I've replaced BrcmFirmwareRepo.kext and BrcmPatchRAM2.kext with BrcmBluetoothInjector.kext, I haven't had even one issue with BT; comes back after sleep every time. I've extensively used my headset, way more than regular, done 2 cold boots about 3 days apart, and of course the laptop goes to sleep/wakes at minimum 5 times a day.

About 3 days ago, I even re-downloaded and have been using Android File Transfer (used bluetooth for all my transferring needs the week prior; flawless), and there isn't anything to complain about.
I'm sure while a lot of hackintoshes definitely benefit from BrcmFirmwareRepo and BrcmPatchRAM2, the Elitebook 8470p without a doubt, works much much more reliably with basic injection.

Also, I've noticed that my webcam doesn't stop working after sleep anymore either—never, may be some link there. It's like having all the stability/reliability from Yosemite back Only deviations from the guide I've done are keeping FireWire enabled, and also automatic wake when lid is opened (convenience for the win!). Powernap also works great, without passing any darkwake flags on boot.

Just for reference:

Chipset:        20702A3
Firmware Version:    v14 c4096
Vendor ID:        0x0A5C
Product ID:        0x21E1
HCI Version:        4.0 (0x6)
HCI Revision:        0x1000

So anyone with the same vendor/product ID, suffering from bluetooth issues, I'd highly recommend at least _trying_ the injector kext, nothing to lose.
Thanks again a TON, to Rehabman, I wouldn't have been able to make it work without him

Without a firmware loader, certain bluetooth features will not work.

Android File Transfer is known to conflict with BrcmPatchRAM.

Well, I guess I just haven't ran into any scenario where BT didn't work as expected. Airdrop and regular file transfer to/from other devices is solid. Along with BT headset working very reliably, any possible trade off is worth it at this point for me.

I keep reading the hotspot function requires iOS, I wouldn't get caught dead with an iphone so that's never going to be an issue I'll most likely give BcrmPatchRAM another shot after Sierra is released. For now I'm just glad everything I care about works, & really well. Getting to keep android file transfer is a nice little convenience too.

Best of luck finding the culprit for intermittent BT with sleep/wake cycles

Advanced BT4LE features such as handoff, instant hotspot are not likely to work...

I don't have any such issue...
