Hardware Questions and Recommendations

I was really surprised about it, but I ran this on a WRT3200ACM after installing Bluez with nothing connected to the USB ports and this is what I found:

I can confirm that by using bluetoothctl I was able to scan and find nearby Bluetooth devices which are known to be real (it found my laptop).

Can anyone else who has the same model confirm?

Is BD address random or correct from the label?

Yeah it’s correct, I forgot to redact it but whatever.

Basic BT operation is that you first pair devices, then enable matching “services” in both ends, You will hear a lot of OBEX endpoints, whose are not PAN.

The third (almost useless) radio, Marvell 88W8887, has WLAN, Bluetooth 4.2, NFC and FM capabilities.

NFC is still useful as WPS…

Sure, if you can get it working :wink: I just doubt (m)any(one) has tried that so far. The way it is implemented on the AX3000t (don't own that device myself) indeed sounds like a cool feature (not well integrated into OpenWrt, but that sounds reasonably possible), how to make the 88W8887 sing and dance would be another question now.
