Title: Can SDIO mode be used together with FLASH mode (MOD-WIFI-ESP8266)
Post by: bigg on September 02, 2015, 11:53:02 pm
It's not clear from the MOD-WIFI-ESP8266 webpage what SDIO mode does exactly.

Basically I want to communicate with the MOD-WIFI-ESP8266 module using RX/TX (via UEXT) where I want the MOD-WIFI-ESP8266 module to give me the readings from GPIO4 and GPIO5 as I see these pins are made available (assume I can attach something here) or I want to send an instruction to MOD-WIFI-ESP8266 via RX/TX to change the logic level of these two pins.

So trying to work out what mode do I put the module in to do this.
