Gen 3 improvements update - 12/17
More specifically, we’re in the process of prepping a firmware release for the SOS-7 fix you described, which we’ve linked to an issue with the low level 802.15.4 driver from Nordic. We’ve worked with them to pull in the fix they provided and will make the rc.27 firmware available as quickly as possible.
