- Sun Aug 18, 2019 8:39 pm #83510 I have an ESP-07 that doesn't seem to want to boot into normal mode. It programs fine, I reboot it into normal mode and the boot log looks fine, but after that it doesn't do anything. I've programmed testing with the AT firmware and the latest micropython firmware and both have the same results....nothing. AT just sits there and doesn't give me any echo feedback for my AT commands. Micropython doesn't broadcast as a wifi access point as it should on boot. It's like it "boots" but doesn't know to start any scripts. Any suggestions? thanks

Booting into normal mode, the boot log looks good.
