Arduino Yun USB host

Post by naman »

I would like to know if it is possible to implement a wired communication link between the Arduino Yun (USB host) and an Android phone using a standard USB to micro USB cable? Also, if a phone is connected to the USB host port on the Ardino Yun, will the Yun attempt to charge the phone's battery ? Could this lead to power issues on the Yun ?

Thank you in advance for any help !!!

Don't see why you couldn't do that.

Yes, the Yun will attempt to charge the phone. I don't know what the limit is - I couldn't find an Arduino doc that discussed the power limitations of the Host port.

Thank you !
I was wondering if I take a normal USB cable and disconnect the +vcc (red wire) leaving the other three wires connected, USB communication should still work right, given that the Yun is powered externally through the micro USB port. In this case the Yun will not charge the phone's battery ?
