Hi! I'm a college student working on a project using ESP8266. We're using I2C to communicate with the microcontroller, but I can't find the I2C address on the datasheet. Does anyone know what's the I2C address for ESP8226? Thanks!

There is no I2C hardware, so the chip does not have an address.
Also device addresses are only needed for I2C slaves and afaik there's only software for a bit-banging I2C master available.

@Rudy got a working ESP8266 Slave using Native SDK attached to an ESP31 Master, but he has never published his code yet.

Thank you guys! So I'm supposed to use serial (Tx&Rx) to communicate with the microcontroller right?
