While the internal Bluetooth module in my development Newton is sick with some unknown hardware problem (it doesn’t send, maybe the 3.3V line got loose), I spent some time to see what the problem with the PICO card and Blunt 2 was. Seems like things are actually quite ok, the card uses regular byte I/O, not DMA, and there were just some bugs in the code. The only irritating thing now is that as soon as I try to send some L2CAP packets, it returns a hardware error. Well, time to restructure the code so that I’m able to have a bit more control over timing, maybe add some delays here and there…
