Hyper-V is nice if other solutions fail for you (like credential guard on Windows prevent VMWare from funcitoning). I personally like the integration with WSL and so on. It just works, most of the time.


Most annoying for me is the issue when creating an external switch which fails with a bunch of errors like „Cannot create a file when that file already exists. (0x800700B7).“ or „Adding ports to the switch … failed. The operation failed because the object was not found.“. Usually the recommendations are uninstalling other VPN clients or running „netcfg -d“. This never ever worked for me.

This especially happens, if you try to bind an external switch to WiFi interface.

Even the MS Fixit failed. It even messed up A LOT. I won’t use that one again.


After a lot of Googling I found a comment below a post which I thought is worth preserving. The folowing blog entry has a user comment. This solves the issue. The blog entry itself doesn’t… Check the comment:


Actually it’s quite easy. This is how is works:

  1. Open Network Sharing Center (just to be prepared! You need to be kind of quick)
  2. Click ‘Change Adapter Settings’ in the left-hand menu (leave window open for later)
  3. Create the new External Switch in Hyper-V Manager. Or, you can also use New-VMSwitch PowerShell cmdlet. Both methods work.
  4. While the “Applying” dialog is spinning away, or the PowerShell Progress “dialog”, switch over to the network adapters dialog you have open in Control Panel. (now you need to be kind of quick)
  5. Disable your WiFi adapter
  6. Reenable your Wifi adapter
  7. Check in the network adapter settings if your external switch has been created

Thanks „Craig S.“ for this info! Saved me a lot of time! I hope this preserves this hint until it’s fixed by MS.

Hardwarewise you only need your CC2350 board, a Rasperry Pi which is newer than the first version and a bunch of (preferably) female-female cables. This does not work for Raspberry Pi 1 as it doesn’t have the required GPIOs.

From a software point of view, you would need to have WiringPi installed and have the according coordinator or repeater firmware ready. This will be explained in the later process.


First of all, hook up your CC2530 with your Raspberry Pi. Therefore connect the following PINs.

GND or G
RES or RST or R (reset)
P22 (DC)
P21 (DD)

Raspberry Pi
Pin 39 (GND)
Pin 01 (3.3V)
Pin 35 (GPIO24, BCM19)
Pin 36 (GPIO27, BCM16)
Pin 38 (GPIO28, BCM20)

Flashing the CC2350

Make sure you have WiringPi installed. If not, follow these steps.

git clone
cd flash_cc2531

This should now contact the CC2350 board and return the chip id. If this return something like 0000 or ffff you have to go back and check the wiring! The result should be

  ID = b524.

Usually you will find an expected result of „a524“ on the internet. This is also a valid result, but for the USB stick type of hardware. In case you are having a CC2531, you will get „a524“ as a result. But then I would be impressed, as the wiring should be different.

Afterwards download the coordinator software and unzip it


Now erase the chip

sudo ./cc_erase

This will give you something like
ID = a524.
erase result = 00a2.
as a result. The chip can now be programmed with the coordinator firmware using the following command

sudo ./cc_write CC2530ZNP-with-SBL.hex

The expected result would be

  ID = a524.
  reading line 15490.
  file loaded (15497 lines read).
writing page 128/128.
verifying page 128/128.
 flash OK.

This should give you a fully functional Z-Stack coordinator. This now needs to be hooked up to either your Raspberry or maybe even a ESP8266 to be used. Or connect it to a zigbee2mqtt server.

Flugbuchung. Es gibt unendlich viele Seiten. Alle tun irgendwie das Gleiche, manche nerven mehr oder weniger… Wir sind bei momondo gelandet. An sich super; insbesondere, weil es um einen Gabelflug ging. Das kann leider nicht jeder. Wir sind dann bei eDreams gelandet, da hier der beste Preis geboten wurde. Die Seite wirkt von Verhalten und Angebot fast identisch zu Opodo. Ein Schelm wer böses denkt…


Einfach mal buchen….

You have moved your library or deleted it accidentally? You lost the „Already watched“ flag?


Just in case you have a keyboard attached: Go to the movie list and just press „w“ for „watched“. This will take a couple of seconds and then set it to watched.
Absolutely annoying. Even if you’re having the scraper set to „local nfo only“ this will probably hit you. You could set the corresponding flag in the advancedsettings.xml but this will only help when exporting/importing the settings. But it’s probably still going to mess everything up.

So just hit „w“ for all the movies you’ve watched and you’re fine.

Who knows me know that I love Android.

This is going to be a short post. I hate the fact that Google is going to call the (at THIS moment) new OS K*tK*t. I will not write the whole name due to search eninge reasons which I don’t want to support.

Well, Google starts to annoy me. After turning off Latitude, this is the next step to make deals like this. Stick to what you were praising.


P.S. a 5.0 would have been nicer. BTW, what happens after Z?

Maya Calendar

If you can read this, it may be already over. According to some people the world will end this Friday (21st of Dec 2012). If you’re still there and reading this afterwards, let me know by leaving a comment 😉

See you in 2013!

Why start another blog if there are already millions out there? Well, I never intended to start yet another blog. All I wanted is some sort of knowledgebase for myself. When thinking about how to achieve this, I came up with the idea to share my thoughts.

Evertime I get stuck with some annoying issue regarding any topic within my „digital life“ (maybe there’s more to come, we will see) and find a solution, I’m planning to post this here. This way I know what I did and maybe this helps someone else. Everyone knows how valuable it is to find some hint in a forum, blog or somewhere else when searching the web.

So in case you came here by a search engine and found a solution, I would be happy if you let me know!
