So for my capstone project I've decided on a myoelectric controlled (think robotic prosthetics) wireless computer mouse. From my little reading so far, I can avoid the pc side of the bluetooth stack entirely by conforming to the Human Interface Device profile on the device side. The way I read it, it should be basically connect and play, no drivers needed.
I have some decent info on the analog side of picking up muscle contractions, but other than the Bluetooth HID spec, not much info on the communication.
I'm looking for advice on a uC to bluetooth connection (or uC with bluetooth on board?) and it would be great to see some kind of pseudocode layout of what the Bluetooth HID is looking for from the hardware side.
I'm familiar with AVRs but willing to learn PIC, ARM, etc. if they are significantly better suited to the task.
I just discovered BlueGiga Modules... looks very promising for ~$26. Self contained HID stack, uart to uC, and radio in one surface mount part (not ball grid). Anyone have any experience with these?
In the BlueGiga datasheet it states to line the outside of the pcb with vias every 0.3" I've never done an RF board... is that typical?
Thanks!
tl:dr Any comments on BlueGiga modules and the HID profile? Different suggestion?
