I suspect it's more primitive than the E2's PBL so I doubt a passkey is required. Request 00 always replies with a NAK in PBL V3.1 but perhaps it does something useful in the earlier version and was changed to be a constant NAK later? Do you get anything from request 01?
I haven't tried 01 specifically, but pblq pings stuff with request 02 (GETVERSION) on connect, and I don't get any response. I'm not receiving *anything* from it, not even the 0x06 when PBL interrupts the boot sequence. At this point I suspect I definitely need a capturing scope to try and see if anything at all is coming out. Alas, they're not cheap. Incidentally, I also took the lid off the Pocket Dockit. As expected it's calculator technology --- ICs glued directly to the PCB with resin blobs poured on top --- but I do notice a bunch of pads labelled Vdd, GND, RESET, SDAT and SCLK. SPI, perhaps? There may even be a real PIC under there... -- ┌─── ｄｇ＠ｃｏｗｌａｒｋ．ｃｏｍ ───── http://www.cowlark.com ───── │ "...it's not that well-designed GUI's are rare, it's just that the │ three-armed users GUI's are designed for are rare." --- Mike Uhl on │ a.f.c
