I have ESP8266 module and had WIfi V2.7.5 installed and working fine. I then saw the V4.x and decided to flash it to the ESP8266 via web update feature.
After that I was no longer able to connect to it.
I need to figure out How to upload the firmware.bin file from WIFI v2.9 to the module.
Can anyone help he on how to program the ESP8266 chip. I have the USB to TTL Serial Adapter but don't know what software to use to flash the file
Placed an order last week and no response at all. Posted in the forums and no reply?
Here is the documentation for loading firmware.
