The model that IoT Hub connected devices use is that they will never accept incoming connections. IoT Hub devices never act as a 'server', and this is a crucial part of the security model in Azure IoT. The definitive model on this is encapsulated in Clemens Vasters' 'Service Assisted Communication'. Therefore devices are always 'polling' an external service ...

Any read/write operations will be slower. However, if you don't want to stream Full HD videos or other heavy content that requires that kind of data transmission rates you'll be fine. Most of the time people just tend to recommend the new stuff. Especially in IoT surroundings just using the one that is enough is often better since it's often using less ...

Probably not. The list of supported hardware for Windows 10 IoT shows which devices are currently supported. The majority of these are single-board computers and the like, rather than regular PCs. Notably, though, some lower-end CPUs by Intel are supported — mostly products of the Atom, Celeron and Pentium range. It may be worth checking what hardware your ...

Tor seems overkill for what you're trying to do. If you want to prevent sniffing of data on the network, simply communicate with the server using SSL by installing a certificate on the server. You may also want to pay more attention to firewall rules to block incoming traffic using netsh advfirewall firewall The pi is not very secure if anyone can get ...

There are 4 standard SDA ratings that I'm aware of: 2, 4, 6, and 10. Basically, the number corresponds to the minimum write speed in MB/s that the card is capable. So for instance, a Class 4 would have a minimum write speed of 4 MB/s, whereas a Class 10 would have a minimum write speed of 10 MB/s. As Helmar mentioned, this means that the Class 4 will be ...

Turns out that the ground cable between the two microcontrollers had been dislodged. Putting that back in place fixed my problem.

I posted this same question to the Microsoft forums and got a reply from IoTGirl saying that WiFi Direct is an option: Windows IoT Core WiFi Mesh I need to confirm whether the RPi3B supports WiFi Direct and then also find out if it supports many-to-many via WiFi Direct. (if anyone has any experience on this, feedback would be much appreciated) Hope ...

CTS and RTS are for flow signaling (Clear To Send) and (Request To Send). If you want to use 4 pins and you find out nothing is flowing through, you may want to pull CTS down to GND. In one post OP claimed I have the Arduinos communicating properly without these pins in use.. There OP had Arduinos communicating, they at least can survive without flow ...

Yes, Windows 10 IoT runs on any x86 or x64 processor running faster than 400 Mhz and 256 MB of RAM. The SoC compatibility list is for the unusual and non-x86 processors that it supports. Windows IoT Core only supports running a single UWP app that launches at startup, which could work for your webserver use. IoT Enterprise supports a more typical Windows ...

Look what [1] tells: Troubleshooting Install issues Error: Failed to unpack Windows 10 IoT Core installation package If your installation fails with the above message then you need to run the setup.exe using the Administrator account. This error message could appear even if you are logged in as a user who has administrator rights; it has to be the ...

No. There's no emulator for a bunch of electronics that sit on a bench. Welcome to the trying world of embedded software development. You could write your code so that you 'mock' some of the inputs, but unfortunately there is little choice other than plugging it in and switching it on. If you're doing Windows 10 IoT Core, with a UWP UI, you can build a lot ...

I am not sure if Win10 IoT supports vbscript. It needs the command line tool "devcon.exe" I copied it from my bigger solution, i didnt checked for missing code. Today i would write it with powershell. But you will get the idea. Set goFileSystem = CreateObject( "Scripting.FileSystemObject" ) Set oWshShell = CreateObject("WScript.Shell") Set oWshSysEnv = ...

The following articles covers UWF exclusions. Write filter exclusions. Based on our findings, the UWF exclusion c:\windows\system32\config, being present will cause this issue. If removing the exclusion, with the command uwfmgr file remove-exclusion c:\windows\system32\config and then restarting the issue will likely be resolved.

You should be wiring in the UART directly from the fingerprint scanner to the Raspberry Pi. Do not try to convert to USB because then you have an unnecessary device driver problem. There are samples for reading from Serial UART on Windows 10 IoT core that work reasonably well.
