Can't get it to work at all on Raspberry Pi Zero 2 W (v0.4.1) #176

Open andrewjbennett opened 1 week ago

andrewjbennett commented 1 week ago

[edit from the future: I flashed the same image onto the same SD card and followed the exact steps that I outlined in this comment below, and it worked fine.... so I must have messed something up with the various things I tried to get it to connect originally? (including things like manually connecting to the wifi network))

I've been having problems trying to get any wireless AA dongle to work on a Toyota RAV4 2023 hybrid (wireless AA isn't available in the car by default in my country), so I figured I'd play around with this to see whether I can at least get any more debug info about what's going wrong.

I've flashed the image onto an sd card and I'm running it successfully in a Raspberry Pi Zero 2 W (successfully as in, it boots and I can SSH in etc), but I'm struggling to get anything working, even with the DHU, before I even get the car involved.

It looks like the phone can't maintain a connection with the Pi? I'm frequently getting messages like "Bluetooth device already connected, disconnecting" (not sure if that's a problem or expected?), as well as my phone repeatedly associating+disassociating from the Pi. Occasionally the phone will report an authentication problem with the wifi network, but it's clearly authenticating enough sometimes, since it gets a DHCP lease etc.

Snippet from /var/log/messages:

The DHU can't find the USB device (but also IIUC there would be different logs saying that it's enabled the USB, if it had made it that far?):

[I]: No device found ready yet, will retry shortly...
[I]: Found 11 USB devices.
[E]: Couldn't find/access compatible USB device.
[E]: Failed to start Google Automotive Link.

Any suggestions on what to try next? I've tried two different phones which have both had the same problem.

Is it a problem that I'm connecting to the wifi via my laptop first (to SSH in and view the logs) before I connect it to my phone?

Thanks!

This happens for me also on a suzuki vitara 2017...

It connects to bluetooth but when it automatically tries to connect to wifi the phone screen flashes and it disconnects from Bluetooth

Yes, it waits for the TCP connection from the phone before enabling usb, which never seems to happen in your case from the logs. Laptop being connected should not be a problem. Seems like after the bluetooth connection, wifi is connected, but then it disconnects. Make sure not to connect to the wifi manually on phone while it is connecting.

@Ashtray1807 This looks correct and looks like wifi works but may be an issue with USB. Doesn't look like the same issue. Logs might help.

Ashtray1807 commented 1 week ago

@nisargjhaveri Where can i get the logs from? Sorry, i'm new to this.

@Ashtray1807

Where can i get the logs from? Sorry, i'm new to this.

You can get the logs by connecting via SSH to the Pi from your computer, either just reading them via SSH, or copying them to your computer via something like SCP.

The steps to do this:

(disclaimer: I don't endorse any of the tutorial links below, I just found them on google and they seem reasonable)

To view the logs:

  1. From your computer, connect to the AAWirelessDongle wifi network
  2. Follow the instructions from somewhere like:
  3. The IP address of the Pi is 10.0.0.1, the username is root, and the password is password
  4. From there, you can type cat /var/log/messages to see all of the logs

To download the logs:

  1. Again, connect your computer to the AAWirelessDongle wifi network
  2. Use something like WinSCP (on windows) or just scp on MacOS
  3. Again, the IP address of the Pi is 10.0.0.1, the username is root, and the password is password
  4. From there, you should be able to browse the files on the pi; the one you want to copy out is /var/log/messages (so there's a folder called var, and inside that folder there's one called log, and inside that there's a file called messages)

(I haven't checked whether there's already instructions for this somewhere on this github; if not feel free to put these, or an improved version of these, somewhere more visible)

The DHU can't find the USB device (but also IIUC there would be different logs saying that it's enabled the USB, if it had made it that far?):

Yes, it waits for the TCP connection from the phone before enabling usb, which never seems to happen in your case from the logs. Laptop being connected should not be a problem. Seems like after the bluetooth connection, wifi is connected, but then it disconnects. Make sure not to connect to the wifi manually on phone while it is connecting.

Ah cool, I was connecting to the wifi manually, so that probably caused problems.

Unfortunately it's still having problems with not being able to stay connected to the wifi network, even when I don't try to connect it myself.

(44:af:28... is my laptop, 8e:09:aa... is my phone; I've turned off MAC randomisation in case that was the problem, but it also didn't help)

It seems a bit sus that I can see these logs about how my laptop is allegedly disassociating from the wifi, while it's still connected enough to the wifi to be able to keep tailing the logs in real time... but definitely on my phone it seems to be having a hard time staying connected.

I've tried two different phones for this already, I'll see if I can find any other phones to try it on.

I'm suspicious that it might be unhappy with the AA wifi network not having internet available, but I've explicitly told my phone to allow it to use that network even though it doesn't have internet, which I would have thought would solve that problem?

andrewjbennett commented 1 week ago

I removed all of the bluetooth devices from the Pi, and I'm now trying on a third phone, which is maybe making some progress? But still not working....

It's clearly in some sort of loop, looking at just the aawgd logs it shows this happening in a loop:

When it gets to the "Bluetooth launch sequence completed", the phone has an AA popup like "to continue, select Android Auto on your car screen", then after a few seconds it stops showing on the phone, and aawgd goes back to the start of the loop: Found 1 bluetooth devices

Note that once the thing pops up on my phone, I try connecting DHU on my laptop, which just says [I]: No device found ready yet, will retry shortly... (but I also think that there'd be a different message in the logs if it had gotten the USB part ready?)

@andrewjbennett when trying to connect to AAWirelessDongle it asks me for a password Screenshot 2024-09-09 094324

@Ashtray1807

when trying to connect to AAWirelessDongle it asks me for a password

Have a look in the readme file (the main github page): https://github.com/nisargjhaveri/WirelessAndroidAutoDongle/?tab=readme-ov-file#getting-logs

Connect to the device using wifi (SSID:AAWirelessDongle, Password: ConnectAAWirelessDongle, see hostapd.conf).

BTW, since it sounds like your problem isn't exactly the same as mine, you should probably create a new issue for it, rather than reusing this one.

reach2rv commented 1 week ago

I am having the same issue. phone shows looking for Android auto and wifi keeps disconnecting when in connects screen flicker and it again shows looking for android Auto

andrewjbennett commented 6 days ago

Update: It works!!!

I built it from HEAD rather than using the v0.4.1 image, and needed to have both the data micro usb plugged into the car, as well as extra power plugged into the power micro usb port.

Without the extra power it partially worked, but gave an error when trying to actually connect to the car. With the extra power, the problems went away.

I'll do a diff between my build and the v0.4.1 release to see what might be the cause.

andrewjbennett commented 6 days ago

Update 2: I flashed the v0.4.1 image onto the SD card (rather than the one I built myself), and.... now it works too? I'm quite confused.

Here are the exact steps that I followed:

Initial laptop setup:

  1. Download sdkmanager from the android SDK cmdline-tools thing
  2. Install the android auto DHU: ./sdkmanager --sdk_root=~/src/android/commandlinetools/cmdline-tools 'extras;google;auto'

Initial phone setup:

  1. Remove all existing/saved connections/devices related to this (so forget the "AAWirelessDongle" wifi network, and delete the "AA Wireless Dongle" bluetooth device)
  2. Plug my phone into my laptop
  3. Run DHU via /src/android/commandlinetools/cmdline-tools/extras/google/auto/desktop-head-unit -u (which was installed in laptop step 2 before)
  4. Observe that it detects my phone, and that after ~20 seconds or so of initializing, it pops up with the android auto UI, showing me google maps and my phone's GPS location
  5. Close DHU, and unplug my phone

Initial Pi setup:

  1. Obtain two micro USB cables (high quality ones, which can do data)
  2. Flash the (previously-downloaded) image onto an sd card (the same SD card as I started with):
    • $ sudo dd if=/home/andrew/src/dad/raspberrypizero2w-sdcard.img of=/dev/sda status=progress
  3. Put the SD card into the pi (specifically, a "Raspberry Pi Zero 2 W (SC1176)")

The steps from there:

  1. Plug a micro USB cable from the Pi's data port to my laptop (which powers on the device)
  2. Plug a micro USB cable from the Pi's power port to a USB power supply (which adds extra power)
  3. From my laptop, switch from my home wifi to the AAWirelessDongle wifi network, and ssh into it (ssh root@10.0.0.1), then watch the logs (tail -f /var/log/messages)
  4. On my phone (which has no saved connections) connect to the AA Wireless Dongle Bluetooth device that shows up
  5. Don't touch anything else on my phone. Don't manually join any wifi networks, don't change any settings related to anything. Just leave it alone.
  6. In the logs that I'm watching on my laptop (via SSH), observe it doing the bluetooth connection to the phone, then setting up the wifi, then starting the USB
  7. Run DHU again, and observe it finding the Pi ([I]: Device 'My Own AA Wireless Dongle 0123456' (vid=18d1, pid=4ee1) supports AOAPv2, starting accessory mode...) and initializing etc
  8. Don't touch anything else
  9. Observe that my phone now shows up in DHU, the same as it did before when plugging it into my laptop via usb cable

My best guess for what happened here (in terms of why it didn't work the first time, but it did work when I flashed the exact same image onto the exact same SD card again) is that I inadvertently messed up some internal state or config etc, with the various things I tried to do to get it to work?

nisargjhaveri commented 4 days ago

Thanks @andrewjbennett for experimenting and reporting in detail. Glad that you were able to make it work.

I don't know why it wouldn't work with your first flash.

For having to have two cables connected, can you also experiment with a couple of suggestions in https://github.com/nisargjhaveri/WirelessAndroidAutoDongle/issues/88#issuecomment-2332544722? If we can figure out a solution for this as well, it would help a lot.
