This topic will be updated fortnightly (next update will be on May 6th) with the status of our new firmware engineer’s progress. The work and updates had previously been paused while we focused on onboarding our new team member. They have resumed the work on this project in earnest.
You can be notified whenever this topic is updated by enabling notifications through the “bell” icon on the right side of the topic page under the scroll bar and select “Watching” (there is a tutorial here)
