HP Prime wireless kit

[Kevin Ouellet]

The defective USB issue is a problem that was present in the first two firmwares. Back then, when you connected the calculator with the Connectivity Kit open, it would check the calculator files at a rate of about 1-10 KB/seconds, so if you had about 600 KB worth of programs on your calculator, you had to wait several minutes before you could finally do any file transfer. Sending files was as slow.

This problem was fixed in the 3rd firmware. It's still slow, but nowhere as bad. I think it takes about 10 seconds now before I can finally send files and file transfer is about 10 times faster than it used to be.


The first two firmwares also became very unstable when you had both the connectivity kit and emulator connected to the HP Prime simultaneously, but now that file transfer from the emulator is no longer possible on my model I guess it's a moot point.
