Yeah it’s not great. It seems it’s only the RAK boards that support the OTA updates and even then it doesn’t work well. I’ve been discussing in our local Meshtastic group here as I know some people are using Android to do OTA updates on the RAK devices so will try again later and see if I can get it to work. I’ve got a node that I’m planning to have installed on a telecommunications tower and once it is up there I won’t have physical access to do firmware updates so need to find a solution.
