I guess this will be part II of another blog I wrote called What! My Azure Percept DK Devices Are Being Retired???. In that blog I mentioned how the Percept devices that were not cheap are now going into “retirement.” The only way to keep using them for other things is to install the last “Unsupported” firmware update before March 30th. This is my blog about how to install this update since you can no longer do OTA updates on existing devices at this time.
So recently I started working on another IoT project which lead me to breaking out all my old development kits. I previously wrote a blog called My Azure Sphere Needs Reset where I walked through recovering an old Azure Sphere Development Kit I had. So I decided to write another few blogs following how I had to do the same with all my devices since I couldn’t really remember any of the configurations and some of these devices had been configured for long gone IoT Hubs and tenants that don’t exist anymore.
