If you are experiencing modules connecting and disconnecting it may be best to update the firmware.
You can perform a firmware reset by following the steps below:
1. Open the PaletteApp and under the help menu, open the menu and open up "Palette Updates". For Mac users, you can simply use the keyboard shortcut (CMD+,) to open the Preferences window.
2. Select "Reinstall Firmware" from the list in the Palette Updates menu, you should see a dialogue open up like the one below. Ensure that you have your Palette core connected to your computer directly avoiding the use of a USB hub. You will need to remove all the modules from the core and hit "Update" to continue.
3. After successfully updating plug back in your modules and check to see if the modules are still connecting/disconnecting.
