AAWireless - General discussion and support

[Spool77]

I've been using my AA wireless for about a month now. It has been flawless. What I'm wondering is if anyone has any suggestions to reduce the heat of the phone when using it. I'm using a Samsung Z Flip 4. It gets very warm just using AA wireless and downright hot if I try to charge it at the same time. I originally tried a wireless charger with a cooling fan but that didn't work. Charging it with a cord and leaving fast charging off still heats up quite a bit but it's doable. Though this defeats the whole purpose of the aawireless.

For now I've only been using the aa wireless for normal commuting and short trips and just not charging at that time. For longer trips I just plug the phone in for normal Android Auto.

I realize this is completely phone dependent and not a fault if the aawireless unit itself. Was just hoping someone had maybe some suggested settings or something I could try to reduce heat.

Thanks in advance

I use also a wireless charger with cooling fan. It is made by ESR. This works pretty well also during summer.
I modded my case to have a mangetic ring to improve the positioning and also the fixation on the wireless charger.

I'm just wondering if any Xiaomi users' disconnections have lessened since the upgrade to MIUI 14/A13?

I upgraded my Poco F3 (EEA) a few days ago and since then I haven't had a disconnection over several hours of driving in areas that would normally guarantee AA to disconnect. I can still manually create a dropout by disabling/enabling mobile data so that issue has not been fixed, but random ones have stopped.

An unrelated issue with calls dropping after 29m 50sec appears to have been fixed too (Vodafone network). This is a bit of a contentious issue, but it's supposedly down to Vodafone's SIP Session Timer Refresh not working in conjunction with 4g calling (VoLTE) or Wireless calling enabled. It requires a fix from Vodafone or for the handset manufacturer(s) to support their unusual requirements. I have double checked and made sure 4g calling is enabled and I'm on 4g for preferred network... calls no longer stop at 29:50.

I took and update of Android Auto 9.0.630834 earlier in the week, but I'm sure I had disconnections afterwards. Maybe it's just a carrier services or Vodafone update and I'm getting a better signal?

That's the same charger I got. The charger itself is great and if I'm just streaming music via Bluetooth it works awesome. But the combo of aawireless plus wireless charging is just too much. I think a lot of it is just the flip 4 being a less than ideal form factor to keep cool. I know I've seen reports of the flip heating up quite a bit during gaming as well.

I don't know how high of a temp will cause damage. I know I've seen as high as 46c at which point the phone will shut off the wireless charging, which in turn shuts off the fan on the charger.

 

[SOFO888]

46c is too high.
40-45c is the max according to different battery data sheets.
I monitor the battery temp in summer and stop charging at 39.7c. I reach this temp after 15-45 minutes in summer time (depending on outside temps). In winter times I can leave my phone for 2 hours on the charger without reaching 39.7c.

Hi @Snirpo, any advice about manual connecting?

Yes, this is already kind of possible by enabling start/stop and selecting some random Bluetooth device to start the connection (not the HU handsfree), so it will not actually start based on BT handsfree. You can then start the connection manually with the the "force connect" widget and kill the connection from the notification. If you want we can work together on making these things part of the public API. Please join us at https://join.slack.com/t/aawireless/shared_invite/zt-1rgddavyq-BKI4rW_Lh0tYRVTOaAPU4g

Hello, I'm on beta test with firmware 3.0.
I'm very interested in using AA through CP cause my car(Mercedes) has poor AA interface as you know. Being not MBUX, it displays CP full screen which is very cool. I've installed v3.0 and set CP and AA through CP enabled but keep failing to connect. Blue light keep blinking and my phone blinking from time to time but nothing had happened. Is there any options I can try? I'm using Samsung Note20 with my Mercedes E300 for your reference.

I (my son literally) have made some simple app with two very very large switches (easy clickable during the driving without losing the look to the road and focussing to hit some miniature text-switch) named "Disable AA" and "Enable AA". This app when launched does nothing untill "Disable" is pressed - it blocks AA service in Android (package hide) so AA connection drops and I can easy use origin car BT features without crazy AA phone service. "Enable" makes AA unhidden and wireless (or wired as well) connection is re-established.
Disadvantage is that hide-unhide package commands require the phone to be rooted (no problem in my case). You could probably do it without any problem on the AAW hardware level.
From my POV, the best possibility (optional) could be to block phone service via AA only - leaving map and other services running. But this I guess is realy hard (or impossible) to do.
Joint to the slack if something.

Maybe try the passthrough mode?
Have you tried the set (AAW+your phone) with other car, or your AAW but with other phone?

New update released for Xiaomi mi 11 lite today, it is the first global miui 14 / Android 13 for my device.

It is MIUI 14.0.2

Connected via AAwireless as usual.

Tried to change mobile data manually from

4G/LTE to 3G = no disconnection
4G to 2G = no disconnection
3G to 2G = no disconnection
3G to 4G = no disconnection

Disabled mobile data toggle = no internet = no disconnection

So what would be the result ?!

 

[italodance]

Test

The Xiaomi issue only happens when mobile data is lost and reconnected. You can reproduce this issue like this:

This is on a Motorola MA1 and it will happen with all dongles or native AA Wireless HU's on Xiaomi phones.

Tested this Xiaomi issue and all fine. Tested several times and fine.

Just to clarify, you were on the Global 14.0.1.0.TKBMIXM ROM then received an update to 14.0.2.0 and it has fixed the linked data/wireless issue?

Or do you mean you upgraded from A12/MIUI13 to EEA 14.0.2.0.TKBEUXM and you no longer have the data/wireless issue?

Nah I was on the global 13, as I said above this is my first miui 14 upgrade. Yeah no longer this issue.
Took some pics with and without mobile data:

Can you go into Settings > About phone, and provide details of the MIUI ROM you're on, including the letters within the brackets? It would also be good to know what Android Auto version you're on.

Here you are:

So it looks like you have a Mi 11 Lite 4G and AA beta.

You're the first person I've seen mention that MIUI14 fixes the data/wifi issue so I wonder if it's an extended AA timeout added to the beta that's stopping the dropout. Have you enabled Start/Stop in the AAWireless app?

@Snirpo is that a Redmi Note 9 you used for the video above? It doesn't look like it will get MIUI 14 unfortunately.

No, never needed start/stop. I will stick to this update and don’t jump to miui future updates.

 

[italodance]

Updated to new AA version which was released today.
Tested about 2 hours driving and all fine. Disabled mobile data toggle several times then back. No issue yet.

 

[Netzmark]

As my app (the one with AA process hide/unhide) is not a good solution (requires entire AA "registration" process to come through), so finally I use Start/Stop mode. It's because I don't want to force an AA connection every time I get in the car.

May I know how should look the process of the connection establishing?

When I'm connected and want to break it - notification and "stop", it's clear.

But how to make a connection? I can't see any switch for it. I can run AAW app but connection is not getting (searching AA... and nothing). So, I go to settings and choosing "Save" - it establishes the connection. Is it normal way as intended by author? Seems be little weird, isn't it?
