Once again I'm cannibalizing parts to try to save money...
I'd really like a bluetooth adapter to use with my attiny but I don't want to spend $50.
I have an old trendnet TBW-101UB (v3 the non see through case ones) that I bought for less than $20 originally. I took it apart and it has a nice little
general purpose chip on it a BCM2045. I found a very meager datasheet here, http://www.alldatasheet.com/datasheet-pdf/pdf/175091/BOARDCOM/BCM2045.html , according to which among PCM and USB interfaces, it also has an SPI interface on it. Well it runs off 5V (at least the 5v support is on the board if not) and has SPI . unfortunately I have not found a more detailed datasheet on it. Could anyone help me find it, or point me in the direction of a very cheap serial to bluetooth or otherwise something usable with an arduino. I do have an other better bt adapter, might try taking it apart and see whats in that.
This could benefit a more people though, if we could find a cheap usb adapter with a decent chip in it that can be repurposed relatively easily. These adapters are a lot cheaper than any arduino or other kit I found so far.
