SOLVED : boAt Airdopes 131 Bluetooth Headset Windows 10 Connection issue

 Hello,

I received my new boAt Airdopes 131 Bluetooth Headset on the 31st of December 2020. They were working fine and seamlessly connected to any mobile device. 

But when I tried to connect it with my laptop, a Windows 10 Dell it was able to connect but my laptop was not accepting it as an audio device. Although it was showing as connected but for some reason as a peripheral device. Check the attached image 

The options as displayed in the above box was missing.

I searched the net for a solution and mostly found a similar kind of problem with Apple Airpods. And because I got no other solution so I started to troubleshoot with what I had. So, tried the following 3 prominent solutions.

1. Remove the device and add it once again, switch on and off the Bluetooth service and try again. Restarting of course
2. Uninstall and reinstall the driver for the Bluetooth device.
3. Add on an entry in RegEdit as Value 24 so that the connected Bluetooth device is never disconnected.

I tried all the above and no joy. As none were addressing the main issue of the device was not recognized as an audio device.

I did some R&D on my own and resolved this issue. 

And I would like to see if someone else is facing a similar problem or not. 

Please post one comment on this post and I will post the complete solution with process screenshots. 

Thanx

AWS EC2 Apache File upload and move issue [RESOLVED]

Hello Everyone,

If you have purchased a fresh new instance on AWS which runs RHEL 7+.

And you are running PHP based application and trying to upload a file and also to move the uploaded file from tmp folder to a desired folder using. PHP functions like

copy() or move_uploaded_file() 

Now while trying to achieve above you are getting permissions errors and warnings.

You have tried everything like giving all folder permission  as 777 and made Apache the user and group owner for every file and directory under /var/www/html. And if still no joy then my friend you are a victim of SELinux.

I banged my head for hours figuring  why this simple and straight forward is not working. Finally found RHEL 7+ got SELinux installed and enabled by default. And SELinux blocks Apache to move files irrespective it is part of the same group as the folder permissions are set.

So you have same issue then start by checking if it is enabled by command:

/usr/sbin/sestatus 

The first row will say the status of SELinux, if enabled it will say enabled. And if it is enabled then most probably the reason for Apache not able to move files.

For fixing the issue just need to disable it, open the config file for SELinux:

vi /etc/selinux/config

And find a variable named SELINUX and set it as 

SELINUX=disabled

I tried SELINUX=permissive but no joy with it.

Then need to restart the system to take effect. Following works well on AWS.

shutdown -r now 

After restarting it did resolved the problem.

I did server hardening like, Permissions and ownership's I changed,  I changed them back and checked once again and everything worked well.

Do check and let me know in comments if any other issue you faced,

Thanx

Windows 7 Blue Screen uTorrent / µTorrent is running FIX

Hello,

If you are running Windows 7 and you had left the system running as some things are been downloaded from uTorrent / µTorrent. After some time you see a Blue Screen of Death with some error number and only way the system would work further is by hard restarting it.

If one thinks by restarting the system or reinstalling uTorrent / µTorrent will fix this issue then one has mistaken,

From my research on the net I found this issue comes due to access number of connection opened by uTorrent / µTorrent for downloading stuff, it very common if the there are many seeders for a specific file, in Windows 7 this will happen instantly.

If you download and install a Blue Screen Reader Tool from download.com then for this particular problem you will find the cause of blue screen which will appear as

Probably caused by : NETIO.SYS

On the net one will find different solutions of installing a windows patch / upgrading, changing some windows configuration, even upgrading RAM and uninstalling few softwares like MaAfee. But as the problem started with uTorrent / µTorrent so the solution has to be with its configuration.

I tried an tested this solution and it is working fine for me.

1. Got to uTorrent / µTorrent and open Options -> Prefrences -> Bandwidth.
2. Set the numbers in Number of connections as minimum as you like
1. Global maximum number of connection 15
2. Maximum number of connected peers per torrent 12
3. Number of upload slots per torrent 1

You can play with numbers as per your requirement, but try to maintain the number in between minimum limits and you will be fine and safe from blue screen of death.

Thanx
