- Wed Aug 05, 2020 11:48 am #88201 Does anyone have a link to any documentation or firmware, I am having no luck obtaining any of these after a few hours of looking.

It is the esp 8266-01 module I have connected to my STM32

The current software installed is:

AT version:1.3.0.0(Jul 14 2016 18:54:01)
SDK version:2.0.0(656edbf)
compile time:Jul 19 2016 18:44:44

Anyt help or advice will be much appreciated!!

but they didn't built a version of AT 2.1 for esp-01. I have it here
https://github.com/jandrassy/UnoWiFiDev ... T_V2.1.zip

The flashing command of AT2 with esptool is

Code: Select allesptool.py write-flash @download.config

I recommend to change in download.config file flash_mode to dout

and the commands reference

Regarding STM32 using Arduino, I didn't realise that could be done, for now I will stick with the HAL with C that STM provide.

Thanks again!

- Thu Aug 20, 2020 6:54 am #88401 The updating of the ESP-01 looks tricky to do (not had a go, or bought the parts to update the firmware yet)

Im wondering if I can save time by using a different ESP module which will already be equiped with the MQTT AT firmware such as ESP12E

Could anyone confirm weather this is possible? It might be cheaper and easier to buy one that is ready made

Cheers
