a microcontroller that implements an entire wifi network stack. can serve as a client, a server and even an access point.
things are moving fast
this document was written with ESP-12E in mind although as far as documentation goes all firmware versions should run on all hardware version
Current can spike above 300mA so use an external power supply!
AT Command Set (original firmware)
The AT commands
Pyesp8266 (Guy Zyskind) - Python code for wrapping serial AT commands
WeeESP8266 - arduino library for wrapping serial AT commands
To get into boot loader mode set the following pins:
GPIO 0: LOW
GPIO 2: HIGH
GPIO 15: LOW
(if you’re using the huzzah board just press the reset button while pressing the GPIO10 button, let go of the reset button and then let go of the GPIO10 button. the red led should be lit but dimmed).
When in bootloader mode run the following:
$ sudo esptool.py -p <serial_port> write_flash 0x000000 v0.9.2.2_at_firmware.bin
