Bluetooth problems with Xperia C4 - Android Wear - Motorola 360

[Guich]

Hello,

I have a serious problem with my new Sony Xperia C4 Dual phone
I'm always losing the connection with my Motorola 360 smartwatch.

The first time I start everything, I can pair my phone with my watch.
Everything is working fine (watchfaces, apps, notifications, etc).
But randomly (can be 1 hour or can be 1 day, when the phone is too far from the watch, after a phone restart, or ...) the Bluetooth connection is lost and will never come back.:smileyrolleyes:
If I could restart the connection that would not be that serious but... I can't!
Android Wear will then start hanging on "Connecting" state and it will not reconnnect until I completely restart the pairing process.

The only way is to reconnect is :
1. Delete the watch in Motorola Connect
2. Delete the watch in Android Wear
3. Hard reset the watch (otherwise it's impossible to start the pairing process)
4. Turn off and turn on bluetooth on Xperia C4
5. Disconnect all other Bluetooth devices (like car audio and BSP10 Speaker)
6. Restart the pairing process
The whole process is taking about 15 minutes and 30% of the watch battery. (because every apps needs to be reinstalled)

What I did so far and did not fix the random disconnection problem :
-Hard resetted 2 times the phone
-Hard resetted 4 times the watch (2x on 5.0 and 2x on 5.1 Android Wear)
-Restarted many times the phone
-Restarted many times the watch
-Tried with the "Sony Smart Connect App" disabled on the phone
-Tried without any extra app on the watch (uninstalled trackID or Sony Music, for example)
-Updated all the apps on the phone
-Tried with a "Blank" phone and "Blank" watch (did not install ANY application)

What I can say :
-The problem occurs even in Android 5.0.2 or 5.1.1 on the watch (Motorola has just rolled out the 5.1.1 OTA)
-The problem occurs with different Moto 360 Watches (tried with the watch of a friend, same problems)
-The problem occurs only on the Xperia C4 (Dual) phone. (works great on a Zopo ZP999, Wiko Highway and Galaxy S3)
-Even after resetting, it is sometimes difficult to find the watch in the Bluetooth list, while every other phone can see the watch perfectly!
-Bluetooth hardware is working perfectly, because I can connect to my car, with my BSP10 speaker and another Bose SLIII Speaker.

Additional information for the watch :

Motorola 360 Watch 

Build LDZ220

Android Wear 1.1.1.2006643

Google Play Services 7.5.76 (2002306-534)

Android Platform 5.1.1

Additional information for the phone :

Android 5.0

Model E5333 (Xperia C4 Dual)

Build 27.1.B.1.81

Smart Connect 5.7.18.401 (11 june 2015)

What I think :
There is something that is preventing the watch from being connected properly in the Sony extra Apps.
I think the Smart Connect and Throw (and maybe other) extra apps are bringing a lot of trouble to the Bluetooth connection with the watch.

Since 2 days, Motorola has just rolled out the 5.1.1 update of the Moto 360 watch, the update is now enabling WiFi.
I connected my watch to the wifi and the "Cloud sync" connection is working perfectly in Android Wear.
When there is no Wifi network, the phone/watch are trying to connect back with Bluetooth... and the problems can begin.

Other problem : when the watch is connected to the phone, immediatly after making NFC contact with my Sony BSP10 speaker (to pair them), the connection is lost between the phone and the watch. So if I use my speaker i will have to hard reset my watch.

In fact... every morning I take my watch and I need to start that f*c*in pairing process because of the software bug on the phone.

Can somebody help here?
Is there any update planned?

Thanks in advance,

Guich

Hello,

This will be my second topic here (and probably the last) after this one :

(I was experiencing problems to keep my smartwatch connected with my Xperia C4)

After updating android Wear (Google), updating Smart Connect (Sony), updating Connect (Motorola) , updating Spotify, installed the latest firmware from Sony, hard resetting my watch dozens of time, hard resetting the Xperia C4 device 3 times, disabling Smart Connect application, contacting the Sony Support and so on, changed my device with another one (my vendor as accepted to exchange it), now I just gave up and now I have another phone.

The whole Bluetooth part of the Xperia C4 is just buggy at this time.
Streaming music to your car, connecting to an external speaker (even a Sony BSP-10!), connecting to your PC, connecting with your smartwatch.. it's FULL of bugs. You will be disconnected for no reason, definitly loose the connection with your watch every 2 days, sometimes Spotify will sometimes play to the phonespeaker (the one for calls, not the external!) while connected to your car, not sending titles to the car, not sending "sound initiation signal", etc all Bluetooth software problems.
Just making an NFC contact with a speaker can drop your watch connection.
Just entering your car can make the phone crash.

In fact the Smart Connect and Throw apps installed by Sony are making A LOT of trouble on that model.

And please don't tell me I should contact the app developers or my car manufacturer!
Okay, i'm not an Android Dev Guru, but i'm not stupid too : I tried everything a "normal" user can do and I think I'm a bit aware of what i'm doing.
I own different cars and I NEVER had such problems.

I owned the following devices lastly : Zopo ZP999, Huawei P8, Wiko Highway, Galaxy S3, Galaxy S4.

I did not experienced ANY problems with ANY of this phones for the Bluetooth part.
Now I have replaced the C4 with a new Huawei Ascend Mate 7 Gold and again I didn't find any issue with Bluetooth.

I have sold my Xperia C4 so "my problems are solved" but I just want to warn people about this phone : if they plan to use a smartwatch or any Bluetooth device : THINK TWICE.

thought i would add to this, I have a similar problem with my z1 compact i just grabbed . very cool phone, but i got it for the waterproof deal for my heavy work and workouts. My main phone is my xperia play, so when i grabbed this Z1c I assumed there would be no problems.

think again.  I use a bluetooth waterptoof blueant pump- which i absoluely endorse as sturdy and waterproof. I upgraded from my play because its getting sluggish and I want to be able to browse my music library when I want to , not in 5-10 seconds. So I get this new phone paired up and it kicks me off the connection and I have to fight with it for about 5minutes to try and reconnect it. Then once I get it connected, if I hold it by the bottom half I apparantly block the bluetooth module so it cuts off. So l test this, I let go , I get music, I grab the phone by bottom , cuts off. hmmmnn.  so  i reserch and find a posted fix... on of all places GOOGLE PLAY? really SONY yu couldnt bother to add it as a HOTFIX?  you give me plenty of other nag but not a hotfix?

okay so I add the stupid patch, and it still doesnt fix the intermittance issue- you know the sound cuts on off on off etc etc.

so, the phone has been pestering me to upgrade to lollipop, I figure what the right? maybe it will fix the on off issue?

NOPE!  and sony how can you not incorporate the goddamned patch that you posted 2 years ago into the new OS release? how incompetent are you all there? so now I will have to keep my xperia play and get rid of the z1c and find something else?
