For those new to message boards please try to follow a few simple rules when posting your question.
Choose the correct forum for your message. Posting a VB.NET question in the C++ forum will end in tears.
Be specific! Don't ask "can someone send me the code to create an application that does 'X'. Pinpoint exactly what it is you need help with.
Keep the subject line brief, but descriptive. eg "File Serialization problem"
Keep the question as brief as possible. If you have to include code, include the smallest snippet of code you can.
Be careful when including code that you haven't made a typo. Typing mistakes can become the focal point instead of the actual question you asked.
Do not remove or empty a message if others have replied. Keep the thread intact and available for others to search and read. If your problem was answered then edit your message and add "[Solved]" to the subject line of the original post, and cast an approval vote to the one or several answers that really helped you.
If you are posting source code with your question, place it inside <pre></pre> tags. We advise you also check the "Encode "<" (and other HTML) characters when pasting" checkbox before pasting anything inside the PRE block, and make sure "Use HTML in this post" check box is checked.
Be courteous and DON'T SHOUT. Everyone here helps because they enjoy helping others, not because it's their job.
Please do not post links to your question into an unrelated forum such as the lounge. It will be deleted. Likewise, do not post the same question in more than one forum.
Do not be abusive, offensive, inappropriate or harass anyone on the boards. Doing so will get you kicked off and banned. Play nice.
If you have a school or university assignment, assume that your teacher or lecturer is also reading these forums.
No advertising or soliciting.
We reserve the right to move your posts to a more appropriate forum or to delete anything deemed inappropriate or illegal.

Hi All, I'm trying to expand my development setup. I have a win10 laptop that handles the average stuff, but being tied down with extra monitors and a real keyboard and mouse it's lost a lot of its mobility. That and a lack of desk space has got me dreaming of other expanses of unused surfaces around my apartment. I'm looking to do more embedded programming on a Linux o.s., and I currently have an ESXi host with a few vm's that can do the job. My spare laptop is an arm based chromebook. Not much I can do to connect to the vm's other than vlc and the like. Any ideas on how I could hook USB dev boards to my chromebook and program them through a remotely accessed VM ?? I haven't been able to find many tools for this purpose.
AS my development machine & my test machine are 64bit windows system with Windows 7 operating System So to give myself a head start I compiled the ComPort project under Windows-driver-samples-master/serial/VirtualSerial2 sample code provided by Microsoft, initial it flashed an error that said as follows "Provider cannot be "Microsoft", must be an organization who authored INF" so I changed the following line in .inx file MSFTUMDF=Microsoft to MSFTUMDF=Sample, then it compiled successfully.
Then I follow the following process to install the driver on the target machine.
1) I copied the VirtualSerial2um.cer file VirtualSerial2um.inf from Windows-driver-samples-master\serial\VirtualSerial2\ComPort\x64\Debug & devcon.exe from C:\Program Files\Windows Kits\10\Tools\x64 to a Sample folder in the C:\ drive of the Target device.
2) Then on target machine I open the internet explorer I went to Internet Options->content->Certificates->import then I selected the VirtualSerial2um.cer file & imported the Certificate.
3) Then on target machine I opened the command prompt as Administrator, browsed to the Sample folder & typed the following command.
I am searching for all btle devices with BluetoothLEAdvertisementWatcher.
It works fine but I need a device handle so I can use GATT api's.
How do I get a device handle from the information provided in BluetoothLEAdvertisementReceivedEventArgs?
