Hopefully they're monitoring this thread and will provide an update.
There's nothing sketchy about it :) Actually the address you're sending it too is one of the guys on this forum and one of our testers. We haven't really had the time to look into a "professional" return process. It's ok for now, cause we don't have that many defective units. If you didn't receive a replacement yet, please contact support, the guys will help you.

Thank you for the reply and I don't believe anyone was suggesting anything sketchy. I've sent two emails that have gone unanswered since last week to the individual on your team who originally reached out to me. What else would you like me to do. Please advise. Love the product. Thanks.

I found a solution for my problem.
1) On the 5Ghz band: I wrapped the whole AA Auto unit into aluminum foil that acts as a Faraday cage to screen rf signals. The 5Ghz signal between the mobile phone and the aa wireless was still strong enough to ensure proper operation. All outside interference were screened. This resulted into a 1000% improvement of the problems I experienced. I now use the unit that way and only get about 0.1% breakups. Will improve the faraway cage even more. I think the wifi might be over sensitive.
2) On the 2.4 Ghz band: Nothing help there. Not even the Faraday cage. I still experienced the occasional breakup. I looked at the signal again and found the following: The carrier bandwidth is only 20Mhz. Most 2.4Ghz wireless equipment works on 40Mhz as default. The reduced carrier bandwidth can be a factor here. Doubling the carrier width to 40Mhz should resolve the problem. To be tested if it can get implemented.
Wow, that's cool, I never thought of that. I will try that on mine. As long as it works on 5Ghz I'll be happy to have it work smoothly all the time.

Do you have a pic of your device wrapped up?

This worked for me too, and I'm using 5ghz on a first batch device. There was a spot I drive by all the time that I would lose connection, but not anymore. Wrapped it in aluminum foil and all is good, not one skip. So maybe the case should have some type of shielding in it? Wish the case would pop open so I could maybe line it on the inside because right now it looks pretty crappy. At least it works though.

If you really want to do that, it's pretty easy to open actually. Just put something in between the bottom and top part and it's open. But it's quite an interesting observation for sure, we'll pass it on to the factory.

If the disconnects are indeed caused by external interference and not by the cable, that would be fascinating.
I will try that aluminum foil thing :p Might look a bit sketchy though.

I figure if you open it up and wrap the insides, either the casing, or the electronics, it shold do the same?

I've searched the thread but couldn't see an answer - I have a generic Android head unit (that supports wired Android Auto - the brand is A-Sure) - I bought the AAwireless on a bit of a punt - as half-expected, the headunit doesn't recognise the AAwireless device. Before I give up on it, are there any settings that might help the headunit recognise the device? Thanks.

Well external interference would mean is would only drop out at certain locations. We know this is a problem in 5Ghz mode and are looking into how to fix it (probably by quite simply changing the channel). I have a spot here in the NL where it fully drops out, so when I can find some time I'll play a bit with the hostapd settings. Sucky thing is: we use 4 types of WiFi chips right now, so I have to check for all of them :(

Please don't concider wrapping the electronics inside unless you are a tech know-how. The alluminium will short circuit the electronics causing irrecoverable damage to the unit as well as the usb port on the head unit. Rather get a nice small little box and package the wrapped aa wireless inside that until the design team comes with a working solution.

Samsung Galaxy s10 + Volvo S60-2. Phone connects to the AAwireless just fine, over the Bluetooth, however when it tries to connect over the WiFi it fails, the message is smth related to "insecure wifi network". Any ideas how to fix this?

Gotcha, makes sense, thanks.
 
I'm going to get some foil tape and wrap the inside of the case, see how that goes.
I opened the case and covered the board with masking tape, then wrapped it with aluminum foil. I did not wrap around the front where the USB C connector, reset button, and LED are. I then just put it in the case pushing the pegs in the 4 corners through the aluminum foil. So far, it's working just as well was the external wrapping was. My first attempt didn't work where I just put a layer of foil on the bottom and a layer on the top. Wrapping it was necessary.

Ok, I'll do it that way rather than the foil tape, which I have to buy, I'll try this first. Good idea with the masking tape.

Hmmmm I'd rather wait for a fix instead of covering my device - I haven't checked to see if they get warm or hot but wrapping it up could end up doing more harm than good imo. Granted - I haven't had any issues with stutters or disconnections. For those that have tried using both network settings (5 vs 2.4) have you tried keeping the phone right next to the device or tried using a different device to see if you still have the stuttering or disconnecting issues? Seems a little odd that only a few AAwireless boxes are effected by external wifi while driving about. Maybe we need to start posting what phone/android version, what car/year and our batch number to help Devs work things out

With frequencies like this foil will re-radiate signal. You may wish to connect it to the real ground to make it work. Signal power is not what makes the biggest impact, noise to signal ratio is what matters. And SNR is as good as phone and aawiress antennas design permits. If you want wireless signal to be more stable - remove noise (which can creep via power lines) and improve signal (better antenna)

    I wanted provide an update on this to see if anyone has any idea. I ended up downgrading the firmware on my cars head unit to the version that was working perfectly previously. I still have the same situation. Using a cable to my phone AA works perfectly. Using the AAwireless device, my phone connects and prompts me to open AA on my cars head unit however the icon to click on the head unit screen is not there. This behaviour only happens when using the AAWireless device. I am thinking now this is a Android 12 issue and perhaps something updated on my phone around the same time the firmware in my car was updated. Is there anything I should be doing to provide logs on this? There is not really an error I suppose on the AAwireless side but something seems to not communicating correctly. I will be testing on another car to see if the problem persists or not in the coming days.
    We have a support overload since Android 12, it ain't funny... Emil and myself have (almost) zero issues on our Pixel 6s. The only thing I experienced once or twice is Bluetooth cutting out on the Pixel, have to reboot the phone to get it to work again. Stuff is broken for sure... For some it works fine, for others with seemingly exact the same situation it does not. We're trying to find solutions, but we're already pretty overloaded with everything going on.

    Wouldn't recommend downgrading your device (requires @Snirpo or another aawireless dev to do this) because then like me, you'll be stuck on firmware 1.5 with no explanation why someone people are on 1.7.1 and others are stuck on 1.5 and no option to update. I'm also a first gen aawireless AAWireless-eSs19MUQ
    Explanation: some batch 4 devices have been flashed with batch 3 firmware, and at this point we have no way to differentiate them from the backend automatically. So batch 1, 2 and 4 are save to update, batch 3 not, because it could also very well be an batch 4 device. It's causing havoc cause the backend is not really set up for this situation. For now we are only doing manual updates for batch 3 devices.

    Hi !

    I got my AAWireless today. Updated to 1.7.1, and used it with a Pixel 6 Pro on a Hyundai Ioniq 2020 (with the April 2020 head unit SW update).

    It's working fine for ... a few minutes. Then it disconnects. I had about 4 or 5 disconnects on a 15mn trip today while using intermittently maps, spotify or both.

    When it happens, it looks like the LED stays blue, the head unit says the phone disconnected, the phone things AA is still on, and based on feedback from my passenger fiddling with the phone, AAWireless app on the phone still thinks it's connected to the device.

    If you wait long enough (a couple of minutes) it eventually comes back. That or disconnect/reconnect.

    All settings are default.

    Any suggestion ? I couldn't figure out what to do with the "debugging" mode... that said I'm a SW engineer so given instructions I can probably dig out logs etc...

    Some info that may provide some insight to others. I'm using an Xiaomi note 9s (Curtana) and while running MIUI EU 12.5 I have issues with AAW after a call ends it plays through my phone's speakers instead of the headunit speakers. This is a well known bug from MIUI. I tried flashing a few different android 11-12 ROMs and ALL had issues with AAW from aosp ROMs to official lineage os (android 11) and gave up on the idea of a bug free experience.

    However, I flashed a build of MIUI EU 12.6 and I now have a BUG FREE EXPERIENCE of AAW - no dropping out, calls work without disconnecting/sound going through incorrect sources etc.

    My point being: this is XDA - we flash different ROMs some of which are buggy to high hell. If you're having issues with your phone and connections etc please try using a stable ROM or change your ROM to check if you have any luck connecting/resolving bugs. There are plenty of aftermarket ROMs here where android auto via USB functions great but wireless is bugged (looking at you lineage os) just my two cents

    I have a Samsung s21 Ultra on the Android 12 beta. Everything works perfectly for me so far. I haven't seen the change your referring too though.

    This thread is dedicated for AAWireless users.

    AAWireless is a device which allows you to transform your existing wired Android Auto compatible unit into a Wireless Android Auto unit.

    General chat, experience sharing and community support should be expected as well as support from the developers of the product: @Snirpo and myself.
    16
    I just want to leave a big THANK YOU for the developers! You invented a great product and do a great job here.

    Anyone who has ordered the product knows that it is a crowdfunding project, which may also have teething problems. I find it cheeky to get upset about problems, even though they are dealt with promptly here. What more should the distributors do than react to the problems here and offer solutions?

    I also have problems with the device, but I was helped quickly. Even if it takes a few days.

    Dear team: Keep up the good work!

    We fixed the "VW Headunit crashing on skipping tracks" issue now completely. Confirmed it's a bug on the HU side, latency makes it worse. We will probably push a new firmware by the end of this week.
    I will also submit a bug report to Google, cause they can fix/workaround this issue as well for cabled users.

    I've already waited patiently for delivery 3 months more than expected - I ordered In April and was coming in June but now that's looking like October. Now I read on the indiegogo forum that people in the UK are being charged an additional €27 by the Royal mail as the UK is now not in the EU.

    Hi Emil!
    Just received my AAWireless, and will plug in and test tonight. Love the packaging, looks great! However… Since it was shipped from Hong Kong I was forced to pay a rather substantial import fee and duties on this bad boy. I was under the impression that they would be shipped from within the EU? Is it stands now I’m EUR 27,00 poorer :(

    Looks like you are in the UK which is outside EU and also there is no way to pre-pay taxes with shipping company any more either....


    This is a crazy. An additional $10 was already taken for delivery and it was meant to ship from the EU. I suspect the units have been shipped by Royal Mail / Dutch post. The Royal Mail rips off people in the UK because they add another £11 in admin fees on top of the 20% VAT even though goods up to £135 should be exempt.
    See https://www.gov.uk/government/publi...s-goods-sold-to-customers-from-1-january-2021

    So not only has VAT been charged coming into the EU from China, it has also been charged coming into the UK ON TOP of the VAT already paid in the EU.

    This is just rubbish. What the guys need to do is either ship it from Hong Kong which can cost £0.20 (there are hundreds of chinese ebay and aliexpress sellers doing this already
    See http://www.vatfraud.org/blog/stop-s...ons-universal-postal-union-upu-terminal-dues/
    The $10 postage already taken should then be refunded.

    The other way round it is send the item from Hong Kong and to mark the item as a gift and providing it is below £39 there is NO VAT to pay and NO Royal mail admin fee. Actually as the original product was $57 - roughly £41.25 This wouldn't be a crime seeing as we have had to wait soo long. This could also mean the $10 delivery could be refunded

    The other way is to ship it via fedex and state the ex-vat cost coming from china and then add 20% vat that the developer should be paying to the UK HMRC.

    Sadly if that doesn't take place, EVERYONE IN THE UK will feel ripped off because of the poor delivery and poor choices made by the developers.

    Cheers
    Disgruntled in the UK

    First of all, your item wasn't shipped yet since in the June batch, so you could have not payed anything for shipping. Secondly, UK is outside the EU, there was a vote about this in 2016, so it doesn't matter if the package comes from EU or from HK or from US, it is treated the same, it's an import. If we import it from HK to EU, we will pay import VAT on the product, then when we send it to UK, we claim back that VAT and we should pay VAT in UK, since there is no more free trading between EU and UK.

    Up till recently there was a nice option, to pay VAT and Import duty up-front, when you ship to the UK, but this has been changed and now they requires business outside UK to register with HMRC and do HMRC feeling even if they are residing outside UK, a lot of red tape. Since crowdfunding is not a sale, we can still ship the units to UK, but not sure if we will be able to after the IndieGoGo campaign.

    We are also a EU registered company so we cannot (and will not take advantage) of any loop-holes in systems to sell at ridiculously / unrealistically cheap prices.

    About the user who paid 27 euros, it turned out that user is living in DK, but provided the address as UK so his package traveled the wrong way, hence the extra duties and surcharges.

    Not aware of other users from UK having to pay anything additional when they received the package.

    Hello. What's new in 1.5?
    A full changelog for each release would really be appreciated :)
    Thanks for all the hard work!
    Yes, I'll write a full changelog next week from 1.0.0 to 1.5.0 and put it on GitHub + add a link in the app.
