ESP8266 Community Forum

- Sun Apr 10, 2016 12:00 am #45204 So guys I have been able to connect my arduino mini(I'm sure it works for other one's too) to my android though micro USB. The wiring is like this : Android <- OTG female cable -> <mini usb cable> Arduino.

A image and a working design can be seen in this blog as well https://uk.pinterest.com/pin/475552041883187750/.

But when I try to do the same with my ESP8266 E-12, it does say we have a usb device connected but the serial terminal apps in android says no serial device detected.(I tried USB serial monitor and USB Terminal from google play-store and they work with arduino mini). I have tested this with a moto G and a nexus tab.

Any idea, how to get it working? or is it even build-able?

Thank you for your time.

- Sun Apr 10, 2016 4:14 am #45210 Thanks for the prompt reply,

The arduino mini uses a Mini(USB-A) cable where as ESP8266 E-12 uses a micro(USB-B) cable, so I don't see a way to make one replace the other..

Any other ideas.. please?

- Sun Apr 10, 2016 7:52 am #45222 i think this is now the time for you to give us a clear description of what modules you have. pictures would help.

arduino mini and esp8266-12e doesnt have built in usb connector nor usb chip.

usb2serial chips from ftdi at prolific have drivers for android. same with atmel's cdc implementation (used in official arduino uno r3)

the module you are calling esp8266e-12 maybe using chiphead's CH34x usb to serial. not sure if there is android driver for that. i havent tried ch34x.
