Connectivity can be strained if the firmware versions of the M2s and Bees are not the same. If there are any mismatches, you have to do the following:
- Downgrade the M2 to Bee’s version by performing an offline upgrade (please refer here for further offline upgrade instructions)
- Perform an online upgrade for your Bees only to the latest firmware version
- Upgrade your M2 back to the latest version.
Please Note: The order of upgrading firmware is important - if the M2 gets upgraded before the Bees, you may experience connectivity issues.
