Unusual Activesynv via Bluetooth issue

Hi all,
I have searched and searched the forum and the internet but can find no answer to this issue.
I'm using an HTC Touch Dual (Neon 200) that I had set up to connect to my PC via bluetooth for Activesync.
No problems there, it all worked fine. The issue comes with my attempts to automate the synchronization. I had found and successfully used a program called CT Scheduler to start the bluetooth radio and then instigate the "Windows/repllog.exe" file to start a bluetooth activesync.
In Activesync, on the Touch, I go to "Menu-->Connections--->when cradled, synchronize all pc's using.........."
I had the option to select "`USB" or "`DIRECTORSOFFICE" (the name of my PC).
Now, I have no idea how the "`DIRECTORSOFFICE" option got there but I selected it and it all worked fine. I could connect via USB or Bluetooth and the auto-sync worked fine.
BUT, Here's the kicker, after a hard reset, I've restablished all my connections via bluetooth etc. and can manually initiate a sync via bluetooth. HOWEVER in the Activesync connections I can no longer select aything other than "`USB". For the life of me I cannot remember how I got the Touch to give me that other option and it is the ONLY thing preventing the auto bluetooth sync from working.
Any insight would be much appreciated.

Hi and welcome to XDA,
did you do a H-Reset or a new rom flash? the new rom may not support BT Activesync, you should also pair your phone to your PC, that may enable the option

Eh - my bad...should have specified in my OP. This is running stock WinMo 6.1 Professional.

Did you pair to your PC?

Not this time around.....dammit you know that sounds like it might be it! I'll have to a backup, hard reset and try it out.
If that's truly the case and I can get that option available again then I have a really tidy solution for people wanting to Autosync via Bluetooth.
(Although this is probably not an issue nowadays as most phones are coming with WiFi, so I guess people are syncing that way)

OK, got too excited there. Of course I must have paired it with the PC or I wouldn't have been able to Activesync via BT manually right?

Depends what stack you have
Sorry, i don't think i can help
If i find anything, i'll let you know

Default MS BT stack for WinMo Pro 6.1. I haven't changed anything on this ROM at all.
I must have done something during BT setup that allowed that option to appear but I'll be damned if I can remember what it was!
It's not a huge deal as I luckily had a backup with that configuration working, I was just being a bit anal about doing a complete clean install, there were a few programs I wanted to get rid of and felt my phone had slowed up a bit.
Cheers.

Gear S3 Frontier and Nexus 6p connection problems

Hi all,
I'm growing increasingly frustrated with this watch because of connection issues.
When I received this watch in January, I was able to set it up no problem. Everything worked great. I just had two issues-
1. The Bluetooth car system would no longer work because the phone would use the watch as the default headset.
2. Google duo would go bonkers when I was getting a call if the watch was connected.
Both of these issues were solved with a solution found here in the forums-by unchecking the option to use the watch for phone connection.
I noticed immediately after doing that that the connection became unstable. I would disconnect randomly then reconnect. As the weeks went on the disconnections became more frequent i.e. Every 2-3 minutes. Then the watch wouldn't connect anymore. Once the watch wouldn't connect anymore neither would my car. Nothing related to Bluetooth would work on my phone. My Tiles wouldn't connect anymore either.
So I went through and deleted all data and cache related to the three Samsung apps and uninstalled the apps. I deleted all Bluetooth connections. Then reinstalled the apps and connected the watch. Within an hour I was still in the same situation. (With no other things connected to Bluetooth.)
I figured out that if I restart my phone everything works again for about 20-30 minutes.
I'm at the point where I don't feel like it is worth keeping anymore. I can't have anything else connected to Bluetooth and I have to restart the phone so often that it just doesn't make sense.
After reading through the forums here it doesn't sound like this is a common problem. Is there something I am missing? Is the watch defective? Any suggestions is greatly appreciated.
Thank you.

You could well find the issue is with your phone and not the watch. I initially used my S3 with a Samsung phone that went bust. I went back to my Nexus 5 and found I had some issues and one app had disappeared from the app store. I contacted the app firm who told me that they were aware of it but it was Samsung that was blocking the app. On going back to a Samsung phone the app was available again and works fine. Can you check your S3 with a different phone?

I also have a S3 and a 6P. Disconnect the S3 Bluetooth from your phone Bluetooth settings and it should connect to your car. You should still see the "Gear S Plugin" notification if you swipe down on the the phone. You should still receive notifications on your phone but the Bluetooth will connect to your car. Connect the S3 to your phones Bluetooth again if you want to answer calls via your watch. Hope this helps.

I have the Mate 9 and the Frontier... when i enter my truck i just press airplan mode on the watch turning off all connection. bluetooth from phone to truck connects 1-2-3....

Clarification
Hi all,
Thanks for the responses. Probably because of my long rambling post there is a little misunderstanding of where I'm at now.
Right now my problem is that my phone can't stay connected to my watch. I have nothing else connected via Bluetooth to my phone. Once it can't connect anymore, I have to restart my phone in order for it to connect again. And then it only stay connected for a couple of minutes before disconnecting.
It is like the Bluetooth gets locked up on my phone by the Samsung gear apps.
Maybe it's my phone. Maybe time to get a Pixel.
Any suggestions are greatly appreciated.

Try this. I do it when I lose notifications. Go to Bluetooth on your phone. "forget your watch" it will disconnect. Reboot phone. Then re pair watch and phone after reboot using your phone and the watch (not the gear app). That usually fixes most problems for me.

Xtrons Wifi and Bluetooth issues with PE98MTVPL Octacore Oreo Headunit

I recently purchased a PE98MTVPL, headunit.
Generally happy with it but there are a couple of issues.
1. It initially connected to my wifi, but now it won't even see the router. I started by not re-connecting to the router. I told it to forget the router so I could try and get it to reconnect and now it doesn't even display my router in the list, but it does offer me other people's routers to connect to though. My phone is getting full signal from the router when I am in the van next to it.
I've tried doing a network reset, but it doesn't work - the system retains all the old network information.
I've also tried doing a factory reset and that does nothing at all.
2. I have been able to connect one phone and the ODBII dongle via bluetooth, but it won't let me pair anything else, even though the bluetooth is registering that a device is available.
Again network reset and factory reset don't seem to get rid of anything.
3. The DAB reception is good when stationary both with the engine on and off. But when moving there is loads of feedback whine whenever the steering wheel is turned, which makes it pretty much useless.

What did Xtrons support suggest?

No response as yet. I have asked them the same question. Will post their response when I get it in case it helps anyone else.

So the response from Xtrons was to send me a link to a firmware update file. I've downloaded and tried to install, but the update fails at the 'mcu update' stage. I've asked Xtrons for advice but no response. I suspect the update fail is something to do with how the files are structured on the SD card after I've unzipped them. Any advice?

I have the Xtrons PE88jccpl (Android 8, Octa Core) sometimes the wifi connects perfectly but other times getting authenticating, authentication errors. Also, having problems with the speed when its connected it starts out fast and perfect but slows down to .2 to .3 mbps after a couple of minutes. Xtrons support sent me a link to update and I updated both MCU and android but still getting issues. (I put the img and update.zip on a usb stick and once I inserted it asked if I wanted to update) Not sure if I am supposed to wipe the device after updating android

Sounds like you did the right thing. I've still had wifi issues with my mobile hotspot since the last update so no progress.

Format your SD card in FAT32, then copy the dmcu.img on on your card (nothing else should be on there). Once you pop the card in it should automatially ask you if you want to update. If not go to settings, there is a button "mcu update" try that. If that doesnt work go to recovery mode and choose mcu update.

Yes unfortunately this does not work well on these units. I have tried it with different wifi sticks and different phones, It never runs stable. I ve also tried variuos MCU versions and ROMS (stock and custom).As soon as you disconnect it (eg leaving the car) it might not reconnect (sometimes it does sometimes it doesnt). What helps is to change the password for the hotspot and then reconnect with the correct password. IN that case it somehow goes through the whole registration routine again and almost always connects. But obviosuly thats not a convenient solution. It is an extreme shame that something so simple does not work on these units. Using a 3g stick (not using wifi) works slightly better but still incredibly unfortunate and not understandable that this is not properly implemented. Every smartphone in this world can access the internet through a simcard without any problems:crying:

I recently updated and wiped the android and mcu provided by Xtrons, its reconnecting successfully finally after sleep. However, I am getting speed issues still, after a couple of minutes of driving it slows down to .2 to .4 mbps.

has anyone tried using usb wifi dongle?

Do you mean a 3G/4G plug in one? I've thought about it, but my current phone supplier won't let me have an extra sim. If you mean an external wifi unit instead of the built in one, then no I haven't. The box only has two USB inputs, and one of those is for my DAB+, and the other I use for connecting phones etc. I don't know if it would help though.
The problem seems to me to be something to do with the way the unit is handling IP addressing. I don't know if an external wifi unit would change that. When I gave my the Xtrons unit a fixed IP address on my home router it would re-connect without any issue. For some reason the head unit doesn't seem happy with the IP address changing.

I got TE706PL and the wifi turns itself off I have done the firmware and mcu update and it still does the same thing

Bluetooth auto-reconnect issues

I have OP7 PRO running android 10 and stock Oxygen OS (not root).
When I pair my device to my car bluetooth set everything works fine, but once the connection is lost it will not auto-reconnect the next time i'm in my car.
Moreover, in order to connect again i need to do the pairing again (not just select the device from the existing devices list).
I saw tons of threads online about this with no solution, some mentioned they think it's an issue with android OS and not the phone itself (this is supported by the fact that my wife just got a new Xiaomi and have the exact same problem).
Does it make sense that this is a global Android issue and has no fix for such a long time? did anyone experience it and managed to fix it?

I would guess at an issue with the car Bluetooth. May be theres a firmware update for that ?

That was my first thought, but it seems that the issue is on the device side as i can see that after connecting the device doesn't appear in the previously connected devices list.
As if the phone forgets it for some reason.

I've had occasional problems too. I'm using Launcher 10. Just last week, I turned on my wifi before starting my car as usual. It connected, then disconnected 2 times and then was stable. There's been times where I'll restart my car to fix it. It's irritating but who knows what can be done about it.

I have a rooted stock op7pro and I have a Samsung active2 watch that randomly disconnects and reconnects once or twice an hour. I have battery set to all Samsung apps on my phone to not optimize battery usage and I have no idea why it does this.

I have understood that it's also possible that it depend on the order in wich you connect.
You should first have to connect the car to the phone instead of the phone to the car.
Iow have the car lookup the phone

Yes, i head a lot about people with flaky connection but i hope that was the situation, for me it won't reconnet 100% of the times.
Changing the order of connections didn't work.

Question Bluetooth connectivity issues

I have been experiencing issues connecting to devices over Bluetooth. Sometimes it just works, other times it doesn't work at all, and some times it kinda works but not right.
All of these issues are resolved by restarting the phone, but that isn't a solution because the issue comes back.
3 Devices I have been having issues with
1. S Pen - Sometimes it won't connect to the phone, I get an "S-Pen Missing" message and it will not connect. If I t ry to connect to it manually via nRF Connect (The Nordic Semiconductors Bluetooth App) it tells me that the BLE device has a GATT error. It happens semi-randomly but I can always make it happen by doing #2
2. Car Stereo - This is the weird one, it will connect and play music, but it will not do "calls" if I connect to Discord it won't recognise the car as a Bluetooth device it can route to.
3. Raspberry Pi - This one it appears it will connect to ONCE, and then after a disconnect it will not connect again.
Again, each of these can be fixed by restarting the device, but they happen again after a while. The pen & RPi use BLE, I don't know what the car uses for calls.

Turn off global power management completely in Device Care.
Network reset, reboot and clear system cache from the boot menu.

Ok, I've done a network reset, and cleared the cache partition. I checked Device Care for something like global power management, and I couldn't find anything. Most of the pwm settings are off except the "optomise daily" setting.
I'll let you know later if I have the same issue again.

These, this is a N10+ running on Pie.
To check if you have disabled global power go to Developer options>standby apps, all buckets should show as active otherwise power management is enable.

Are those the only three devices you connect via BT? What other apps do you use that need to use BT (i.e. Galaxy Wear, Apple Music, etc.).
You mentioned "Nordic Semiconductors Bluetooth App." I looked it up. Why do you need a third party generic BLE connecting app? It seems to me that could be the problem. You shouldn't need a third-party app to connect your BLE devices. The S22U's native pairing will work with any BT device that adheres to BT standards.
Try uninstalling the nRF Connect app and see what happens.

The only other Bluetooth devices I have are other in-house hardware, running on SiliconLabs BGM13P chips or NRF52840 chips...
The NRF app isn't a replacement for your bluetooth pairing app, its a debugging app... it can connect to BLE devices and show their GATT profiles, update devices that have Nordic's OTA update code and copy a devices GATT profile to act as a BLE Server.
We use it for testing and debugging.

Ok. I recommend uninstalling nRF Connect anyway. If anything, to rule out the app. How old is your car and the Raspberry Pi? Even though BT 5.2 is backwards compatible, sometimes older BT devices won't work with newer devices. That doesn't account for the S Pen issue though.

I uninstalled nRF connect, and changed all the settings you both recommended. Exactly the same behaviour when I went to leave work. My car stereo would do music but not calls, then when I restarted my phone, it worked. Then when I got home, my S Pen would not connect to my phone, then I restarted my phone and it worked.
Its not a problem of not being compatible, its a problem of something stops working.
Please also note that these devices worked fine together in the past. I am concered that it is either a change made by an update or a Bluetooth chip that is faulty....

OP- Have you debloated at all and if so maybe you've removed something relevant that might be causing these issues?

No, stock image, no OS modification beyond the things that Samsung offers (GoodLock and Stock customisation)
I have our in-house apps for interacting with our equipment (over Bluetooth) installed, but #1 they shouldn't affect anything if they are not open and #2 they don't do this to ANY of our other test equipment.

I would just like to say, that I appreciate the assistance that you are all offering! I have used many forums over the years when looking for support on things and I rarely find a place that is more ready to try and help than XDA forums!

I've seen the issue of the spen disconnecting but only a couple of times and the issue worked itself out within a couple of minutes with me not having to do anything.
I've also have had a couple of wonky issues when connecting a new Samsung phone to my car. I've narrowed down my issue to the fact that when I transfer my data & settings via Samsung smart switch, it includes the details of my Bluetooth pairings. To fix it, I have to go in and delete my Bluetooth phone settings from the car and from my phone and re-pair them.

As cool as I think Smart-Switch is as a program, I actually never use it when moving from one phone to another. The junk that Google drags with me from one phone to the next is already too much, I like to use a new device as a chance to do some housecleaning. So no old-data oddities here.

Hmmm.. Ok. You're probably right about the suspect causes. I know there is a code you can dial to get into diagnostic mode, I just don't know what it is.
The only other option you can try (as a last resort) is to factory reset it. If it is update caused, a factory reset MAY fix it. If you take it to a service center, send it in for repairs, or do a warranty replacement, they're going to factory reset it, or have you reset it.

have you tried running diagnostics in device care ?
or check with this dc
android
Bluetooth test*#*#232331#*#*
samsung
Bluetooth Test Mode*#232331#

I still haven't done a factory reset, but I continue to have the issue.
I have run the BT Test in device care, it always reports good.
I tried the codes, neither of them work as the first one is for vanilla android and the second is for older versions of Samsung firmware.
I've tried completely unpairing from the car radio and re-pairing, disconnecting and connecting from the other device to no avail.

I'm not entirely sold on the idea that it is a hardware fault. It could be a hardware limitation; meaning you cannot connect to more than a certain number of devices simultaneously. I don't know how many BT devices you can connect to at once. I know at least two simultaneous connections (I've only had two simultaneous connections at a time).
You said you have other BT devices in your house other than those three your having issues with. How many are there? How many are you connected to at any given moment?
Is it possible that you have too many simultaneous connections?

When you try to connect to your car.. Did you check under BT connection (your vehicle) to make sure both audio and calls are checked..

Unless having multiple connections causes the BT to fail completely, no. Even after turning the car off and walking away, it still will not connect to the S Pen. The only BT devices I use with that phone regularly are:
S Pen, Car (Music & Calls)
At work I develop devices that use Bluetooth and I sometimes connect to them, but only ever one at a time.
