Hotspot Firmware and Reliability Fixes

· 2 min read

The team has a new release tagged 2021.03.08.0. This release includes a fix to Hotspot firmware where onboarding keys were incorrectly generated, a snapshot bump to 750241, and several reliability fixes that were identified in our Validators Testnet.

Hotspot Firmware Update miner#679

Release 2021.03.04.0 included a fix for Hotspots crashing early on boot because it would fail to get the onboarding key. The fix inadvertently caused a new onboarding key to be generated if there was none found. This is not the correct logic for Hotspots, since the onboarding key is the public key of the Hotspot.

This meant that when a user tries to onboard a Hotspot with this firmware image (can happen if they leave it connected to internet and it received an OTA before they add_hotspot), they will get an onboarding error message.

The fix is to no longer generate a key if none exists.

Consensus Group Reliability Updates

Several improvements have been backported from the validators branch including reductions of CPU/memory use due to better garbage collection of old consensus and election groups as well as a fix to eject bad nodes from the consensus group when proposing a new consensus group. These improvements should lead to smoother block and election times.


We have been beta testing 2021.03.08.0 since March 8th, 2021 11:00 AM PT. Current ETA for GA is March 8th, 2021 2:00 PM PT.
