- Tue Nov 28, 2017 4:45 pm #72139 I have found, that while somewhat operational, the esp01's I have, that are not marked AI Cloud inside, do not fully function with port forwarding activated. It is hard for me to nail down exactly what is happening, but the AI cloud boards work perfect. my two cents for today.

Where I buy my ESP8266 boards from... (Banggood)

- Thu Jun 21, 2018 10:15 am #76554 Today I got some of those "AI-cloud inside" ESP-01 modules and also had some trouble getting them to work. After the initial upload everything looked normal, so I tried to save the settings for station mode. Could not save them. Then the problems started, usually ended with no more connection to the module.

Found the solution here:

It's the SPI flash P25Q80H, there is a patch for available for Arduino. So I applied the patch and compiled a new version, looks like this time it's working without issues.

I attached the .bin file, it's for ESP-01 boards with that P25Q80H 1MB (8 MBit) Flash.
To upload it, start the Basic Flasher Tool and then replace the file in ../build/1M. Use the same name as the old file. The .bin files will be replaced each time you start the tool again.
