Phone & Screen Cycle Back and Forth - tman - 03-05-2019

Just obtained latest version of OpenAuto Pro.



Setup on my Pi3.



When I connect my Pixel 2, I get the ding that it is connecting, the Android Auto notification showing it is connected pops at the top, then the screen on Pi goes black, phone reverts back, screen reverts back, and this just cycles over and over.



Once I unplug I get a USB Comm error and the OpenAuto crashes and I have to relaunch.



Anyone seen this? What info can I provide for troubleshooting. Didn't run Raspiban update after loading, as figured it was blackboxed with the app.



Pixel 2 is also fully up to date.



Thanks,

Tman

Hello,

That looks like a serious power issue. Once you connect your phone it tries to charge from the RPI's USB port. RPI detects too much current drained from the USB port and cut it off for safety reason. You can try to use different power supply (or check the connections and power cable) or powered USB hub. Also as far as we remember there should be an option in Pixels to disable charging when data connection is active.
