Does anyone know do some tablets not read USB data?
I have a Lenovo E7 and I have activated USB debugging and set the baud rate etc correctly for my Vipec ECU. I plugged in my phone (Google Pixel 9 pro) in and it read some data and connected to ECU. So I believe the issue to be the tablet.
When i go to USB connections on the tablet it is greyed out and says not connected.
I don’t think that would be necessary if tablet is otherwise working fine (won’t hurt though).
99% of the time these issues are related to Android USB usage permissions, somewhere deep in Android settings there are list of applications that are permitted to use USB with certain apps. Now, with RealDash closed completely (also ‘swiped off’ from running apps), when you plug-in the USB with ECU powered on, do you get Android system message asking if you would like to use USB device with RealDash?
Have you tried to use a USB hub/doc? I have one on a cheap Samsung tab a8 that I use to modify experiment with new dashboard assets when I’m on the go. It has USB keyboard and mouse.
I also tried it on my pixel 3xl and my pixel 6 pro (as of recently they just ulocked it on the pixel 6 pro, months ago it didn’t work)
However I have no idea nor have I tried to connect directly to my phone with a can reader, as all the USB ones I own do not interface with realdash.
Hey guys, so in the end I just bought a Google Nexus 7 and it connected straight away using the same cable. Success!
However, now I am receiving data but not charging with the Y cable splitter. The last tablet charged but did not receive data (strange). So now I am thinking the USB hub route.
Has anyone any recommendations? It is very confusing, I know only some hubs support charging. I see some need a certain amount of wattage to charge. I would think the 5V from the car USB cable is not enough.
FYI you can build your own USB cable. Just learned that recently. You can go to adafruit website and they have USB ends. I’d get on YouTube and learn about diy usb. I glanced over it a while back but can’t remember details. I’m far away from buying hardware. I’m doing ui designs and planning before I get to that point.
