I have a similar issue. It was working with 1.5.2 for many weeks. I am able to put in safe mode but after flashing, it goes to blinking green. It doesn’t appear to execute any code. Any help would be great.
Mine may be a different issue then, I was on 1.5.2 when this happened. I tried flashing older pieces of code that don’t use MANUAL mode, still same behavior.
My application uses WiFi but switches it off to save power. Periodically wakes up, enables WiFi, and once the publish goes through, switches it OFF again.
But this specific issue is happening right after I do an OTA update of Argon via WiFi.
