Pretty much have to assume that my Bluetooth module is toast.

I note I cannot finds an exact model number? i.e. Model A P02 BPM 0002 00 and a part number AH42 10F845 AA

I found on line one in Australia - however - Model A P02 BPM 0601 part 8H22 10F845 AA

Not sure if I am splitting hairs - assume mine is a slightly later build (do not know what the AH vs the 8H22 reference variation is) and if it will make a difference?
