Are there any big kits of this stuff, or is it all spread out over ten million itty-bitty SKU numbers? I would prefer the former, as I have nephews in desperate need of such things.

Another direction to go with it would be to add a camera. As it stands already, the project might be useful for telepresence in a toxic or otherwise dangerous environment.
Very very cool project, Easton. I like your simple design for fingers.

I figured out a fix, which I will share with posterity. I programmed a microcontroller to spit out “ATL2\r\n” as RS-232 at different baud rates using NOPs to get the bit times right, and fed it to the bluetooth module, watching its response on a logic analyzer, until I could see it talking at 19.2kbaud. Eventually I settled on 115.2kbaud because I want a higher data rate, but one reachable by any terminal I’m likely to use.
So I did stupid and programmed the serial port to a baud rate that I can’t match with any device I have around here. I see SPI is another option for communicating with the thing, does that also take the same AT command set? Then I can use that to set back the baud rate. Or maybe just use SPI for everything and forget the UART entirely. Better docs would be welcome.
