And for today’s intriguing question… I’ve been working on the ESP-12 for some time now – the program has never failed to work on power up… today I wanted to put the code back into an ESP-01 as I only wanted to use GPIO0… same code – same kit – ESP-01 powers up – gives up the usual rubbish on powerup and… nothing.
Works in the ESP-12 – doesn’t work in ESP-01. Tell me I’m dreaming but are they not identical apart from the actual pinout?
I feel like I’ve entered a parallel universe… used to work. I’ve tried spare boards – makes no difference.
