This app allows you to load the AT Instruction Set to you CW01 core.
Links:
You can read all about how to use this instruction set from Espressif here: https://www.espressif.com/sites/default/files/documentation/4a-esp8266_at_instruction_set_en.pdf
and look at this document for examples:

I2C:
The CW01 will try to command the I2C as a master. If you plan to use I2C from your other core, then you need to tell the CW01 to turn off the I2C master usage. You do that with this command:
AT+TEST
RGB Led:
Red and Green:
You can use the standard commands to turn the Red and Green LED on and off (not the Blue), the LED is on this GPIO pins:
Red = 12
Green = 13
Use these standard commands to turn Red and Green on and off - replace x with the above number for red and green:
AT+SYSIOSETCFG=x,3,0
AT+SYSGPIODIR=x,1
on
AT+SYSGPIOWRITE=x,1
off
AT+SYSGPIOWRITE=x,0
Blue:
The Blue RGB LED is different. Turn turn that LED on and off use:
on
AT+TEST=1
off
AT+TEST=0
