Frequent disconnections with ATOTO headunit #7

Closed nu00 closed 7 months ago

nu00 commented 1 year ago

Hi, I have an ATOTO YS102SL (now out of production) with a "Linux" proprietary OS. I tried your project on an RPi4, but it didn't work at all. The head unit didn't even recognize the device. So, I built this fork https://github.com/BluemediaGER/AAWirelessDongle, and it recognizes the RPi, but it doesn't start Android Auto. On the phone (Pixel 8), I get a notification saying "Looking for Android Auto..." and that's all. I also tried the fork on a Peugeot car, and after some tries, it worked fine. Here are some photos I took of the head unit and the log on a monitor connected to the Pi. Note that every time I tap "Reconnect" on the head unit, I get a new address. PXL_20231022_211730527 PXL_20231022_211738242

I'm available for further testing of the project with my head unit; I just need some guidance on what to adjust.

BluemediaGER commented 1 year ago

My fork contains special customizations for my own headunit, which may break functionality for others. Try the main branch of this repo, now that #3 has been merged. If there are still problems that your headunit doesn't recognize the Pi, you can try this branch of my fork.

I tried both the main branch of this repository and the feature/device-ids branch of your repository, but the head unit still doesn't recognize it. The main branch doesn't even activate Bluetooth, while the feature/device-ids branch activates Bluetooth, labeling it as "OnePlus Nord," but it doesn't accept connections. Unfortunately, I didn't have the display with me today, so I don't know what is actually happening on the pi. Is it possible to connect via SSH to the RPi for debugging? I tried, but it asks for a username and password...

yes you can, connect it through the wifi that raspberry pi created, then for the authentication is username = "root" password = "password"

The main branch currently only activates bluetooth after the headunit initiates Android Auto connection, that is the headunit sends the accessory start command, and from your description that might not be happening.

Currently, "restarting" from the headunit won't have much effect. Unfortunately it is not handled very well yet. Best way to retry as of now is to disconnect the RPi and reconnect to cause a reboot.

It might also help to look at the /var/log/messages after doing SSH into the RPi.

Here's the logs of an attempt to use my ATOTO headunit. I'm using a build updated at 8f12cf0b8b395d514dc956ae19c2f98192fe9af9

BluemediaGER commented 1 year ago

The main branch currently only activates bluetooth after the headunit initiates Android Auto connection, that is the headunit sends the accessory start command, and from your description that might not be happening.

The log looks exactly like this is what happens. The head unit doesn't even try to start Android Auto (by sending a accessory start request).

The main branch doesn't even activate Bluetooth, while the feature/device-ids branch activates Bluetooth, labeling it as "OnePlus Nord," but it doesn't accept connections.

@nisargjhaveri Looks like this head unit also needs "real" vendor and device IDs.

Looks like this head unit also needs "real" vendor and device IDs.

Right, looks like it. Any idea if there are vendor and device IDs that we can use freely? Any idea on what some of the legitimate dongles are using?

nu00 commented 1 year ago

looking here (https://source.android.com/docs/core/interaction/accessories/aoa2) the only Product ID for Accessory Mode is 0x2D00. The device ID could be the Google one (0x18d1) since my phone (pixel 8) have the same and it works. Maybe is for the MTP part to be changed (for example use the Nexus/Pixel Device (MTP) 0x4ee1)? Should the headunit have the ability to look to files on the device in MTP? If so I don't think it's actually showing some files the rpi...

nu00 commented 1 year ago

I don't know if it's related, but connecting the rpi to my PC, windows give me an error (USB\DEVICE_DESCRIPTOR_FAILURE), and looking for the VID and PID it shows USB\VID_0000&PID_0002\5&86C20F0&0&2. Maybe this is the problem? Does the main fork start MTP at first?

Depends on what you define as "legitimate", I guess :D I tested two cheap ones from Amazon, and they both showed up as a Xiaomi phone on the head unit. For more expensive models like the Motorola MA1, my guess would be that they simply use their own IDs.

I don't know if it's related, but connecting the rpi to my PC, windows give me an error (USB\DEVICE_DESCRIPTOR_FAILURE), and looking for the VID and PID it shows USB\VID_0000&PID_0002\5&86C20F0&0&2. Maybe this is the problem? Does the main fork start MTP at first?

If this happens with the main branch of this repo, I would kind of expected that. It's not a real device, so Windows probably doesn't know how to handle it. My branch with the OnePlus device IDs shoud get detected by Windows just fine, but it will report in device manager that there are no drivers for it. It's enough to trick the head units into thinking that it is a MTP device. (Updated) I will do some more tests tomorrow. I might have an idea...

nu00 commented 1 year ago

Yes, I've tested your device-ids branch, and it displays the correct VID and PID in Windows. What I was thinking is that before entering gadget mode, it needs to be recognized as an MTP device with an MTP PID. Correct me if I'm wrong...

nisargjhaveri commented 1 year ago

Yeah, it does make sense that we need to use some well-known MTP vid/pid, I was misunderstanding something till now. We can use 18d1/4ee1, should work.

I've pushed a change in device_id branch. Have a look in case I missed anything. We can merge this in main soon, just that I don't have a way to test if these changes will work for these head units.

It is essentially the same change as https://github.com/BluemediaGER/AAWirelessDongle/commit/213d305d279ed38e79d3289ba93d7e1ec5c5052f except I've not changed the manufacturer and product name, I guess that should not be relevant. Also, I've changed the class/subclass/protocol for MTP interface to match better.

nu00 commented 1 year ago

I've tried the your device_id brach and it's still not working on my ATOTO, but we have some progress:

It says USB_STATE=CONNECTED and USB_STATE=CONFIGURED, something has changed..... Still, I don't get anything on the headunit... Note that, since it's a new build, I've remove the bluetooth connection on my phone. I've also tried on the peugeot and it still works as before

nisargjhaveri commented 1 year ago

while the feature/device-ids branch activates Bluetooth, labeling it as "OnePlus Nord," but it doesn't accept connections.

This is interesting. Can you please share the logs with feature/device-ids branch from @BluemediaGER's fork as well?

nu00 commented 1 year ago

Tomorrow I will do it, since I've to build it again. It's possible that, since I've done that test at work in the parking lot during lunch break, that was someone's phone passing by and coincidentally it only showed up when I had the rpi plugged in...

nu00 commented 1 year ago

Ok, it was just a coincidence. Just tried and it dosen't bring Bluetooth up.

Here the logs:

I was thinking: is there any way to sniff the USB traffic between my phone and the head unit? This way, we can better understand what's happening. Do you have any ideas on how to do it?

gamelaster commented 1 year ago

@nu00 for that, you need to have hardware level USB packet sniffer, I don't know about any cheap one. 150$ for Cynthion. But I don't think you need this. The communication is known.

BTW @nu00 Do you still have that Windows USB descriptor issue? Because that would then give a sense why it is problematic.

nu00 commented 1 year ago

No,with @BluemediaGER branch features/device-id in windows it shows up as USB\VID_22D9&PID_2764&REV_0510, but with the device-ids branche of the main build by @nisargjhaveri it shows up as USB\VID_1D6B&PID_0105\0 that are not the 18d1 and 4ee1 @nisargjhaveri set in S92usb_gadget

You may be able to use https://github.com/AristoChen/usb-proxy on a RPi4. I had used it once for something with some modifications. Thought this can be slightly tricky since for AA as the usb resets in the middle and you need to restart the proxy.

We do know how the communication is supposed to happen, but since it is not working on your head unit, might help to know what we're missing.

Are you sure the build went through correctly, 1D6B/0105 is the one we're using in the main branch. Also, you might not need a full rebuild, just ssh into RPi and you can make the same changes as ca7859b2e49b1d30afe32467775b2f6caa5ed7e3 directly.

nu00 commented 1 year ago

Okay, something went wrong with the build, so I manually applied the changes from commit ca7859b, and now Windows shows USB\VID_18D1&PID_4EE1\0123456. I'll let my laptop charge up a bit, and then I'm going to try it. EDIT: just noticed that Windows detect the rpi as an MTP device and let's browse it's content (there is anything but it sounds promising ✌️)

I'm going to give it a try tomorrow, at least we know what's going up...

nu00 commented 1 year ago

@nisargjhaveri, I tried it with the changes from commit ca7859b, and IT WORKS! I apologize for my incompetence with the building; these kinds of projects are new to me, and I'm trying to learn new things. Also, thank you for your work; I've tested it for a while, and I didn't notice any lags in general. I'm going to keep it plugged into my car and try it in the coming days. I'll let you know if something doesn't work.

nisargjhaveri commented 1 year ago

That's great news! I've merged the device_id branch to main now as well.

nu00 commented 1 year ago

Hi, I tested it for a while this weekend, and I found out that sometimes, after a while, it disconnects, and it doesn't accept a reconnection from the head unit because the RPi stays in gadget mode and doesn't go back to MTP. It's sporadic; sometimes it happens after a few minutes, and sometimes after 10/15/20 minutes. The only thing I can do is unplug the RPi from the head unit, reset the head unit with a paperclip (because while I'm driving I can't turn off the car, ahaha), and then plug the RPi in again. Here are the logs when it fails:

gamelaster commented 1 year ago

@nu00 actually, I had issues with dropping of the connection, and I suspect that sometimes, the exact channel is so much busy, that it drops the connection, but it is only suspicion, I don't have this confirmed. Does this happen in cities?

nu00 commented 1 year ago

@gamelaster, to be honest, it happens regardless of where I am. I also noticed that the rpi wifi network is enabled on both 5 GHz and 2.4 GHz. Maybe the phone tries to switch frequencies, and it crashes. However, if you read the logs, it says that it failed reading from USB, so I don't know... A nice workaraund will be to go back to MTP, so we can reconnect easier from the HU

nu00 commented 1 year ago

I've just tried to disconnect Android Auto from the notification on the phone, and the logs are similar, so maybe @gamelaster is right.

We do start the MTP again if it fails. Even in the logs, see these lines, which says that the MTP gadget was started again.

Two things to investigate.

  1. Why is the usb read failing in the first place.
  2. Why is it not reconnecting after we try to reset the gadget to MTP mode.
nu00 commented 1 year ago

I don't know why, but I tried to reboot the RPi via SSH (so no unplug and replug), and after some retries, it started reconnecting to the head unit. Notably, I don't have to touch the reconnect button on the head unit, it makes it worse. It's also hard to debug this issue because it happens randomly

nu00 commented 1 year ago

what about this line? bluetoothd[161]: src/adv_monitor.c:btd_adv_monitor_power_down() Unexpected NULL btd_adv_monitor_manager object upon power down

seems like the bluetooth crashes...

  1. After some testing, I noticed that it's the HU fault for the usb disconnection, it happen also with the phone connected via usb directly.
  2. For the reconnection, I'm not 100% sure, but I think the phone goes in "charging mode" before going to MTP. I would give it a try but I really don't know how to implement it (some advice pls)

We do disable the gadget completely for 2 seconds, which should be equivalent to the "charging mode" before going into MTP. We can try to tweak with the time limit if that's the issue. https://github.com/nisargjhaveri/AAWirelessDongle/blob/main/aa_wireless_dongle/package/aawg/src/aawgd.cpp#L33C14-L33C14

From the logs above, it looks like we do enable the MTP again, but the headunit never sends the accessory start request

nisargjhaveri commented 7 months ago

We have more robust reconnection now with v0.4.0. Resolving this issue for now, feel free to reopen if it still is an issue.
