Hotspot Firmware Release: Improve ECC Slot Handling and re-enable Gateway-rs Packet Forwarding

· One min read

The Helium team has tagged a new 2022.03.29.1 firmware release for Original Helium and RAK/MNTD Hotspots.

This release fixes a regression in ECC key slot handling. Earlier firmware releases specified ECC key slots 0 and 15 for public and onboarding keys, respectively. However, recent releases specified slot 0 for both. This release reverts sys.config to the old spec. Note that slot 15 was only used for some very early first generation Hotspots thus very few not-yet-onboarded Hotspots were affected by the reversion. No action is required by Hotspot owners.

Additionally, this release uses the embedded rust gateway and gwmp-mux processes to forward packets instead of the erlang miner, as a step toward the transition to Light Hotspots.

For those Hotspot owners flashing new SD Cards for RAK/MNTD and original Helium Hotspots, please use this base image going forward. No action is required otherwise, and all RAK/MNTD and original Hotspots will receive this update automatically over the air as long as your Hotspot is plugged in and connected to the internet.


We have been testing 2022.03.29.1 since Mar 24, 2022 09:30 AM PST. Current ETA for GA is Mar 29, 2022 3:00 PM PST.
