I have been a little bit late in informing our dear customers that there is a new revision of the HP Prime firmware. You just need to use the connectivity kit, and when the machine using it is connected to internet, it will prompt you to update both the connectivity kit and any calculator attached to it. The firmware version number is 7820. It improves stability a lot. There are other improvements that you can find here:
