I recently bought a cheapie Bluetooth -> Stereo amplifier board. It works pretty well for what I need and I’m thinking about buying another. Unfortunately the device comes with “SANWU Audio” as the hard-coded BT device name. I’d like to change that to something nicer like “JamBox”, especially if I’m going to have two of these sweetpeas.

Has anyone had experience with re/programming these modules?

My stereo amplifier had this soldered on to it: http://www.dx.com/p/csr8635-2-channel-bluetooth-v4-0-module-black-blue-368089

Possible pinout for module: http://g04.s.alicdn.com/kf/HTB1Med2FVXXXXaIXFXXq6xXFXXXJ/220226238/HTB1Med2FVXXXXaIXFXXq6xXFXXXJ.jpg

I’m starting to think the “Debug SPI” on the chip (PDF: http://www.csr.com/sites/default/files/csr8635_qfn_technical_overview.pdf) isn’t exposed on the outside pins…
