Xperia Z5 :: Bluetooth Connection Drops During Data Transfer?
Nov 2, 2015
I use Polar Flow app to synchronize my training sessions from Polar V800 to the web:Â Polar V800 - bluetooth 4.0 - mobile - [URL] ....
I have upgraded from Z3 compact to Z5 compact. Nothing else changed. Since then the synchronization is almost impossible. The syncing process fails after 30-60 seconds every time. If I am lucky the current training session can be uploaded to the mobile after 5-10 attempts.Â
Bluetooth HCI snoop log was fine on Z3 compact but not on Z5 compact. Wireshark detected some inconsistencies in the Z5C's bluetooth log: it has been cut short in the middle of a packet. So I think the bluetooth connection drops very often during data transfer.Â
Bluetooth communication with my dell laptop was lose after 30 second even if i made the duration of availability is ultimate.Also id and manufacturing of mobile ( mobile information) is not registered
Is it purposely designed that Z3+ dual automatically drops data connection in calls? or it's just something wrong with my phone? For me it is necessary to go online while talking on the phone at the same time. I've tried to deactivate one of the SIM and the same problem persists.Â
I have an Xperia PLAY R800at with 2.3.3. Whenever I'm using my bluetooth device and reconnect to my wifi network, I lose bluetooth packets for 5-6 seconds. This does not happen when I compare against the Nexus S sitting right next to the Xperia PLAY.
This is a really bad problem, and is probably going to result in me not using my PLAY at all.
I have established bluetooth recognition on my MacBook Pro and iPhone. But it won't hold the connection for more that a second. The message on my computer says the iphone bluetooth is off or out of range. Neither of these are true. Any thoughts about why bluetooth connection continues to drop?
I have iPhone 5s with iOS 7.1.2 and I'm experiencing a Bluetooth issue with my 2013 BMW 3-series. iOS randomly drops the Bluetooth connection (Hands Free) to my BMW during a phone call. The phone call is not dropped, but it still goes on in the iPhone, but the Bluetooth connection simply drops.Â
I have updated the BMW Connected Driver to the latest version from URL.... and it does..I suspect the issue is at the iOS side, since I'd day that the iOS 7.1 update introduced it and I did not have the issue with iOS 7.0.Â
sing an unlocked Lumia 800, on operator Claro BR. I have noticed that sometimes the phone downgrades my data connection speed to EDGE and it only shows up the HSPA icon again if I turn off-on the phone. I have tried turing the data connection off and on but it does not work.I noticed that it is more common for it to drop the data connection speed when I go from home to work or vice-versa (it probably changes to another cellular network antenna).But even if I stay in a single location, after a few hours the connection drops too.
Every time that I have been connected to WiFi my phone drops 3G connection.
The only way to get it to reconnect is to restart the phone. After restart the 3G is working perfect for as long as i have been able to test it, but as soon as i connect to WiFi it stops again.

In the last month I've experienced that my phone and smartband keeps dropping the connection. On the phone it shows as eather and x over the smartband icon, or that the SmartBand apps says 'Connecting' without anything happens. Some times it's enough to turn of the smartband other times i need to reboot the phone to get the connection up and running.  I've got all the altest SW for Z5 (32.0.A.6.200) - SmartBand (05.00.12 - 1.7.0.873) and Lifelog (2.9.A.3.8)Since I use the smartband to wake me up in the morning, it's very enoying that it don't work. Until now I've managed to wake up by myself...The phone is charging over night, and in the cradle, with the sound turned of. The phone is turned of with the exeption for notifications. The phone is set to vibrate and make a soft low sound. The Smartband is set to vibrate. If the connection is droped during the night, neighter the phone nor the smartband gives any indication on the alarm.  I've experienced that the phone and the smartband is vibrating, but there are no sound from the phone. Another version is that the phone is vibrating and making a sound, but the smartband don't vibrate. Before going to sleep i check that the phone is turned down, and that the connection to the smartband is OK.
I've just got a new SGS2. I've paired it with a VW Passat from 2011. Everything is working fine except transferring the contact list, only around half of the contacts get transferred -- 125 of 205. I can't find out why some contacts get transferred and others don't. Before I had a Palm Pre 2 and it worked just fine... all contacts would transfer perfectly.
I've unpair the connection several times in the Bluetooth settings, delete the connection in the car and pair again but didn't solve the problem. I've also update some of the key contacts that don't get synced, forced a reload of the contact list in the car menu but nothing works.
with my bluetooth. I have a black berry curve 8520 and I am unable to transfer data with my pc through bluetooth. It pairs correctly with all devices but under the services list it doesnt include data transfer. I have tried refreshing the service list for a couple times but it doesnt work.
I'm unable to sending and receiving files via Bluetooth.
I followed the following steps
1. Swith on the Bluetooth
2. Connected with my another mobile which is having Bluetooth feature
3. Try to send music file to another device
4. First file went successfully ,but from second file onwards it is not transfer data. Showing message as "Pairing with 'Device' Complete, and then 0% showing progress bar always"
When Bluetooth is turned on, my data connection will disappear (i.e. the 3G or 4G icon on my screen will go away) sometime between 30 min to 2 hours after turning phone on (different length each time). I can still make calls, but the data connection is gone until I restart the phone.WiFi will still be able to connect.If bluetooth is not turned on, the data connection is fine, both 3G and 4G and wifi.
Myself and my friend have iphone 4s. we are unable to transfer data or pictures using Bluetooth, how to do this? The bluetooth symbol is not shown though it is made active.
I'm tasked with developing an iPhone app whose first bit of functionality is to connect to a bluetooth transmitting device (our company product), receive data from that device, and use that data to do other important things.
Bullet points: - search for bluetooth device - connect to bluetooth device - receive data only from the device
I am using curve 9320 blackberry handset. I found a new type of problem while using the data transfer via Bluetooth (BTh). If I wish to transfer the data to the sama model i.e. 9320 to 9320 it works fine but as soon as i wish to transfer the data from my 9320 to BB curve 8520 the data transferred failed. On the same time the data from 8520 BB curve to 9320 is nicely transferred on my curve 9320.
I have an e71-3 on the '3' network.I can connect my phone to my laptop and use it as a modem, using the USB cable... but it ALWAYS drops out. It hasn't made it to 1 hour of connection time yet -> and dropped out about 30 times before one hour.Average seems to be at around 25 minutes, but, last night was 47 minutes, and this morning i checked at 15minutes 30secs and it had already dropped out.Is this something that updating firmware can fix? Or am I just left with a stuffed phone that I can't use as a modem? Is it worth trying a different program to connect to the internet? (I doubt it?).
I've had the phone since Monday and have not had a pleasant experience in terms of signal. I manage a little over 300 lines for my company so I know what our signal is and isn't in places. All of our phones typically get great 4G signal and 3G signal around here and especially inside the building. Since I've had the Bionic though it's been really flaky as a lot of others have mentioned. 4G just seems to drop a lot. I've done a lot of speed tests (both on the phone and also tethered to a laptop) and the biggest inconsistency is the upload speed. I am getting 0.05mbps on my upload, but closer to 5-6 on download. The phone itself has been fine, all apps work, speeds are good when browsing actually works and the network doesn't drop. I called Verizon today and he had me check the box for data roaming which was not on by default. So far the signal has been pretty solid where it doesn't drop but it didn't make any changes to my speeds.
I have a Thunderbolt here that gets 20 megabit plus on both uploads and downloads so I know speeds in this area are fine. The Verizon tech pointed me to an update in November that *should* address something with 4G but he wasn't clear on what exactly that was. One other issue I've been having is Wifi. It takes a long time to detect that I am close to my access point. Are others seeing the same issues with uploads that I am or do I possibly had a device with a bad radio?
I have serious connectivity issues with my Nexus 5. Most of the time I am only picking up 2G signal, sometimes the connection drops completely. However, I had a very unstable 3G/H/LTE connection for a few minutes sometimes in the last days.This started after changing the battery and upgrading from Cyanogenmod 12 to 12.1. Unfortunately I did both changes at the same time, so I am not sure what caused this problem.
The following things I could rule out/test: - Another phone (Nexus 4) picks up H+ with my sim - My phone doesn't pick up 3G/H/LTE with another (working) sim - I have checked the connections of the both cables running alongside the battery, I also checked the cables itself. - I fiddled with the apn settings, also I never touched them before and everything worked fine. - I have updated the radio image.
The one thing I couldn't try is flashing an older cyanogenmod 12, because I have no backup and couldn't find one online.
I've tried to connect my Z5 compact with my notebook with Windows 7. There's a bluetooth connection but gives a lot of errors in the device manager. Sony PC Companion 2.1 can't connect it also by bluetooth. I've tried to update my Windows, but that wasn't a solution. I have also updated my phone as well..
I have BB9780 (v6.0.0.285) when Im connected to wifi whether at home any where else it keeps disconnecting every minute or two even though its not in standby mode. I cannot download larger files or watch video stream most of the time because wifi connection dropping from my device, and if I download through carrier it will cost me a lot. I tried to reset network but no use.
When i use LTE I get full bars and everything works fine for a couple of minutes. Then I lose connection. I can not open any webpages, update Twitter or anything else. The bars are full and the 4G icon is there. If I run a couple of apps like LTE Discovery or Network Signal Strength, they both show that I am connected with good quality. But nothing on the internet works. I have checked the APN. It is correct.
If I deactivate cellular data and switch it on again, I have connection for a few minutes again.
If I set it to 3G only, everything is working fine.
I have tested my sim in my wife's iPhone and it works fine, no connection drops.
The phone has been laying around for a while. I just started using it again, but I can not get what could cause this behavior.
Everytime i try to connect to a Bluetooth device my z3+ restarts its Bluetooth before the connection is complete. So i cannot conect to any other device, is there something i can do to fix it or do i have to wait for a software update?
I am using my xperia Z3 to connect with my helmet using the bluetooth connection.  At the begining, when I bought the xperia Z3, when pressing the helmet button to make a request to the phone, the "google lady" was asking about if I want to make a call or anything, it worked out, it was working as expected, but since the phone requested me to make some updates in the apps (also the google app), the google thing does not work anymore. It works the music, it works the google maps and navigation but If I want to "talk to the phone" the google lady says (in spanish "espera") "wait", a grey screen appears with the word "initializing" and actually does nothing. In a nutshell, the google thing does not work using blueetooth anymore. Then I have to stop to drive and manually make the call which is not ideal when you are travelling...
Soo whenever I connect to any Bluetooth device my Xperia will end up blanking out or the wallpaper will stay but no buttons and the phone must reset. Then now that I use headphones the volume is very low to the point I can't hear much. I've done pcc I've reset it done safe mode nothing has worked.
