HP Prime wireless kit

Quick and dirty speed-check on HP Prime ver A 6031 software (same gear as my prior post)

Transfer from Prime to Emu of Spreadsheet containing several 50x50 matrixes of random decimal numbers
USB shows 64Byte block transfers, my 'sniffer' showed eyeball average 500us for each

Of course there is some hand-shaking before the transmission and the Prime seems to chat with the PC periodically.

Not what I expected: the transfer rate is faster going to the Prime.

If my math is right, those are speeds in the 1 to 2 Mb/s range like USB 1 or 1.1
The HP Prime is listed as a 00h class ("unspecified") not 03h (HID)

It should be possible to extend this interface to allow communication with other devices as is done with the 410 unit.

I'm sure someone more informed than I will have more information.
