Nexus 7 can pair but won't connect with BT

I had originally paired my Nexus 7 with my DHD such that they were paired with BT, and at any time I can connect to the DHD from the Nexus and I would have internet access on the tablet.
On the DHD, in addition to the blue BT icon, I would also have a BT tethering notification on the top left of the status bar.
This morning, all that changed – for seemingly no reason.
I could connect fine, but the BT tethering icon was not there on the DHD. The tablet would connect, but it reported that the internet connection was not available.
I tried unpairing and pairing, and rebooting both devices.
Since then, the problem has significantly worsened.
I can still see and pair both devices fine. The pairing code comes up on both devices and I am able to confirm that the codes match and the pairing appears to work. That's where my success ends. I tap on the device to connect, and it says "connecting..." for a few seconds, and then returns to the original, unconnected state. If I touch the device again to connect, it will not only flash up for a fraction of a second "connecting..." and revert back.
This happens regardless if I try to connect to the tablet from the phone, or vice versa.
I figured the BT stack must have been corrupted somehow on one of the 2 devices, so I tried pairing the tablet and phone to my dad's Galaxy Nexus and also his Nexus 7. I can pair anything to anything, but can't connect from anything to anything.
I am rooted on both my devices, but neither of his.
I tried the program "Bluetooth fix repair" from play store, which requires root access, which claims to fix some bluetooth problems. I tried it on both the tablet and phone. After a restart, I notice it has reset my bluetooth settings like the device name, etc. It didn't fix the problem. I can still pair the tablet to the phone, but can't connect.
Any ideas what may have happened and how I can fix it?
Tablet is running stock jellybean with root, and phone is running AOSPx BR3 from XDA.

I've run into the same issues! Trying to connect my GN to my N7 over BT shows that they pair, showing the same PIN, but won't connect. Previously, I could connect my GN to my Xoom but no longer.
I've flashed back to stock on both devices (I'll do so later on the Xoom) to eliminate as many variables as possible, and I'm still getting a connection. GN is now back to IMM76K and N7 is running JRO03D, only change is supersu on both. They connect perfectly fine to my laptop but will not connect to each other. I noticed that some people got good results by turning off WiFi but that didn't help me at all. I know BT worked on my GN because I could connect to 2 different BT units in 2 different cars.
Some people are going to ask why not use Wifi. Well, I have poor reception at home and I'd like to retain internet connection on both while using Tablet Talk (which I have yet to be able to use...).

I'm tethering via bluetooth as well. Its frustrating that when I walk away with my phone, the tablet will not auto-connect via bluetooth. I have to go back and connect the two.

I can confirm I'm having the same issue. Only way to repair is to do a full device wipe. Power on / off doesnt seem to correct.
Confirmed this is the case iwth my N7 and Galaxy Nexus Stock Rooted and CM9 Galaxy Note.
BTW reason people want to do this is because BT tethering has very low battery life cost particularly compared to wifi tethering which will flatten a galaxy nexus in ~3 hrs.
Love to hear if anyone else found a fix for this!

Try This
I had the same issue. I went into the more settings on my phone for Wireless & Networks/Tethering & portable hotspots. Make sure the bluetooth tethering is checked. After i did this i had no issues using my phone internet through BT. I have a T989 running CM9 RC2. My N7 is rooted running the stock rom. Hope this helps.

I can confirm I was having the exact same problem as everyone else and this fixed it for me. The only other thing I had to do was connect FROM the Nexus, not the phone (an HTC Sensation). Trying to connect from the phone was a no-go. Thanks!

Will N4 connect with PTV3000

i know N4 is miracast certified, and pTV3000 is a miracast receiver
does anyone know if someone has actually made this connection happen (demo units etc..)
Thanks!

Miracast receiver -> miracast certified.
Yes, wheels do go on cars.

Android central wrote in N4 review that they didn't get it to work with Netgear Push2TV. I have no idea if it was PTV3000 or some earlier model.

It does not work with the Netgear PTV3000 (Probably because it is only pre-standards compliant).
Netgear is claiming they have an update coming out though to fix it though.

haha too bad your jackass smart reply doesn't hold, since the other 2 members nicely pointed out that yes, it does NOT work
some wheels don't go on some cars, take care

Anyone know of any Miracast receivers that do work with the Nexus 4?
Don't feel like getting buying the $30 Slimport HDMI cable, would rather just put that money towards a Miracast box of some kind.

Thanks for your update. I just get Netgear PTV3000's V2.1.1 firmware update from Netgear Forum. I am not sure whether it can make your Nexus 4 get supported.

I just tried this update, my shipped firmware was 1.0.2 Went fine, but N4 still cannot connect. Phone sees the adapter, but when you tap on it to connect, says "Connecting" and never connects.

Someone know when will be firmware update for PTV3000 to support Miracast?

Progress! 2.1.4 almost connected - ended up with HDCP authentication error. 2.1.5 works. But there is a lot to be desired! There is noticeable lag between what happens on screen and on the TV - maybe around 0.5 seconds and it gets worse if you are more than couple of meters away from the receiver. There are often artifacts showing up, video works but is choppy, audio goes out of sync (audio also plays on the TV).
But good to show pictures and slideshows on TV wireless. But not really HDMI cable replacement. Battery consumption (on phone) is considerable too. Battery shattered down by 20% down in under 10 minutes.

Thanks for posting these. I tried 2.1.5 first, but it had the HDCP authentication error.
2.1.4 works though! However video is constantly choppy and occasionally blocky.

2.1.5 Killed WiDi
2.1.1
Finds the Push2TV adapter, but cannot connect. Nexus 4 can find the Push2TV adapter but cannot connect either.
2.1.4
WiDi fails to connect and HDCP authentication fails for Miracast.
2.1.5
WiDi doesn't connect but Miracast works pretty well. Video and audio is a little choppy though.
For now using stock is best for WiDi and 2.1.5 is the best for Miracast. Anyone else have any news or new firmwares?

Has there been any progress with this?

My Verizon Samsung Galaxy S3 was able to revert my PTV3K's firmware back to version 1.0.13 from version 2.1.5. If you need to revert back to stock, that is an option.
(edit) After it received the Jelly Bean update, it shows this screen upon connecting:
Hitting "OK" will flash the 1.0.13 firmware to the PTV3K.

This is how I get it to work consistently without the HDCP error..
Make sure the monitor is off before plugging in the usb cable to the PTV. So each time you turn off your monitor, you also need to unplug your PTV.

How do I flash the firmware to the ptv3000?

From PTV3000 guide:
9. How can I update my Push2TV?
a. Use your computer and navigate to http://www.netgear.com/stream to check
for and download the latest firmware.
b. Press the Wireless Display Mode / WPS button on the side of the
Push2TV unit for more than 5 seconds.
c. Using the wireless network manager utility on your computer, search for the
Push2TV wireless network name (SSID) and connect.
d. Open a browser on your computer, and you are automatically redirected to
the Push2TV update page. If you are not automatically redirected, type
http://192.168.3.1/ into the browser address bar.
e. Follow the steps on the web page to upload the firmware image you
downloaded in step a and complete the installation.

There is a 2.2.2 firmware floating around for the PTV3000. I can't comment on the Nexus 4 specifically, but it does work with the Galaxy S3 and the AllShare Cast app on it. I have had great performance with it, especially compared to the 2.1.5 that was just absolutely horrible. I would be interested to know what someone with a Nexus 4 and the 2.2.2 experienced as well.
Also, in the 2.2.2 update, it looks as tho the button on the side for switching between WiDi and Miracast isn't used for switching modes anymore and the device is always "listening" for both types of connections. The screen doesn't reference WiDi or Miracast now, just basically says"connect your device".
Thanks

Nexus Player WiFi and Bluetooth Dead?

BACKSTORY: So I just got my Nexus Player about three days ago. I used stock for all of a day and had no issues. I decided I would try Lollirock v2.1. It loaded with no issues and I was able to get it working. I don't have an OTG adapter so I used ADB to configure the wireless and then found ADBControl to control the device through ADB. I got it working but found that it really didn't align with my desires. I also began having Bluetooth issues with the remote. The remote would randomly drop pairing.
I came home from work the other day and found that the box was not responding over wireless. I just reset power to it and, upon recovery, the wireless and Bluetooth were no longer responding (icons gone from status bar too). I decided this was some sort of Lollirock flakiness. I flashed the device to stock LMY47V. The device recovered and it was apparent that Bluetooth didn't work. I couldn't pair the remote and the device wasn't visible when I pressed the button on the bottom. I was able to pair the remote to my phone so this ruled out a remote issue.
I reflashed Lollirock so I had USB debugging by default and attempted to research in a root shell. I was unable to activate wireless. I saw a random suggestion that wireless issues could have been caused by the Use Network Time setting so I disabled that on Lollirock with no better results.
PROBLEM: Wireless doesn't work at all. In a shell, netcfg is not showing a wlan0. I can't seem to make progress because of this. I assume Bluetooth is trashed because of the same problem as with the wireless. I tried flashing an older stock package with no luck. It seems dead, Jim. Any suggestions?

I never resolved the issue and ultimately replaced the device with a FireTV instead. I'm much happier with the Amazon device.

I have flashed probably 30 nexus players with lollirock never once had a problem! I wonder if you had the wrong file in folder or bad download. I left a root.img from nexus 6 in platform-tools and it booted but was acting crazy but remembered that it was for nexus 6 and reflashed was all good!

if you have access to a usb keyboard of some sort and an plug into your nexus player, find and download (sideload) an android terminal app. in the command prompt, enter:
su
service call bluetooth_manager 8
service call bluetooth_manager 6
i found that info here: http://forum.xda-developers.com/nexus-player/help/bluetooth-issues-sixaxis-app-t2987998
hope that helps.

Chromecast wont work

When I try and cast apps using Chromecast, my V20 will either say it cant connect or connects but doesnt cast anything. This has never been an issue using my other android devices. Anyone else having this issue? Ideas of what might be going on?

Hi there, I just tried it and it worked fine for me.

It works fine with all three of my devices. Try rebooting the Chromecast and rebooting the phone.

Off topic, but no. Chromecast is still Chromecast. The app for it (which itself was never called Chromecast, but rather Google Cast) was redesigned and renamed Google Home with the introduction of Google's Google Home device. The app is now there to serve any "Google" device they release.

On my Sony Android TV the app is called Google Cast that's built in and I can cast from my phone or tablet like you normally would with a Chromecast dongle. It seems Sony broke the ability to cast with a recent update to the TV, which is unfortunate because Sony updates are few and far between. I'll just invest in the new Chromecast and bypass the built in app all together. It isn't the phone after all.

I have the same problem. I rebooted the Chromecast receiver and my LG V20 and it doesnt cast, even to a Chromecast 2.0 device. I tried with my old Galaxy Note 4 and it works fine.
I wonder if this has something to do with Android 7.0 Nougat?

I have h990ds and chromecast 2.0 and everything works well ?

I just got my LG V20 and was having the same issue with Chromecast. One day it would work and then the next not. I found it only works if I have my wifi on my LG set to the 2.4mgz. It will not cast if logged on to the 5mgz. I assume most of us now have dual modems. When in my office my phone goes on the 5mgz. So have to change it to 2.4 to cast. has been working every time so far.

Works like a charm for me, both in ChromeCast and Nexus Player.

I have 3 Chromecast, and 3 Chromecast audio, some on 2.4GHZ, some on 5GHZ and they all work fine using my v20 no matter if it's connected to 2.4GHZ or 5GHZ.

Not an issue with Android 7+. Works perfectly for me and many others. If you're still having trouble try some of the troubleshooting steps mentioned above, like rebooting your v20 and rebooting your ChromeCast. You could first try turning your WiFi on & off, as cycling your data connection often helps with connectivity issues (Either WiFi or carrier, depending on the situation. Though obviously it's Wifi in this scenario)

LG V20 and Miracast problems

I can't get my LG V20 to connect to any of my Miracast enabled devices. I have a LG WebOS TV and a LG PH150G Projector and can't get either one to connect. On the Projector, the phone will find it just fine, but when it connects the projector will get stick at Signal Detection. On the LG WebOS TV it will just get stuck on connecting. Any solutions?
SOLVED for me at least! It is a conflict with the App 'AllCast' by clockworkMod. Once I uninstalled the app Miracast works!

I had the same problem trying to get the V20 to connect to a Microsoft Wireless Display Adapter. Suggestions would be appreciated!

That's odd. I have a 4k tv with chromecast integrated and also have an ezcast 4k dongle and both of them allow me to use DLNA and also screen mirroring. Currently using Weta Rom.

I had trouble with miracast too a few months back. Gave up and just used smart share to watch my movies on my phone. I could look into it again and see if I can figure it out.
Edit.. Just hooked up fine first try. Mines not a webos but it is an lg 3d smart tv.

What version of the phone do you have (Carrier)? I have tried to connect to 4 different TV's and Miracast devices without success.
I just tried using Miracast in 'Safe Mode' and it almost works, The status bar changes to blue, and my projector now gets to starting stream, but eventually disconnects.

T-Mobile. I'm on a custom rom but don't thik that is the issue. Have you factory reset your phone yet? I know no one likes doing that, but might solve your issue. It's definitely the phone though and not your other devices. I know the first time I connect it makes me enter in a code from the tv, but after that it remembers the connection. Try going into your tv menu and see if you can connect from the tv to phone side as opposed to phone to tv.. Should have a menu option for it on all your lg devices that are miracast equipped.
Ok never mind saw you fixed it.
