hid-mouse demo instability , help

[gootoomoon]

It looks like much more stable when I connect my BLE device to win8 but when I press the same button the mouse pointer goes different directions can you tell me why? What can I do to solve this ？

Should I pull up the pin or not?

Hi,

What kit/HW are you testing this with? You're into something regarding the pull if you're testing with the eval kit. The behavior can be a bit "strange" and slow if you do not have any pull on your buttons (which the EV-kit does not have)

Best regards Håkon

I just test it with DK(no nRF6700) and supply it with 2 AA battery at the VCC pin. Is there any different between DK and EK? As I know ,they are both make with nrf51822.

Hi, you need to configure your button inputs with a pull up/down depending on what polarity your buttons have. If not, they will float and that can give you some strange behavior (button presses missing or slow, etc)
