0 wjwd Posted November 4, 2023 Share Posted November 4, 2023 Has anyone discovered a solution this? I'm currently experiencing the same issue. I've noticed according to expressif docs, bin version is supposed to be displayed at end of AT+GMR, but it is not on mine as well. Link to comment Share on other sites More sharing options...
