 For the [[en:tech:gw60 | blind project]] I converted the standard TRÅDFRI on/off switch into a button for the blind. Unfortunately, you can't buy one individually. For the [[en:tech:gw60 | blind project]] I converted the standard TRÅDFRI on/off switch into a button for the blind.

 How to open the button is [[http://westsideelectronics.com/ikea-tradfri-on-off-switch-teardown/ | here]] well described. The connections for programming are labeled on the back of the PCB and the connection to the debugger is shown as follows: How to open the button is [[http://westsideelectronics.com/ikea-tradfri-on-off-switch-teardown/ | here]] well described.

-Alle TRÅDFRI Komponenten unterstützen Over-The-Air (OTA) Updates. Darum braucht man sich nicht zu kümmern da es im Hintergrund zum Beispiel durch das Gateway erfolgt. Wollen wir beim Umprogrammieren jedoch gleich die aktuelle Firmware flashen, dann können wir die Daten auch direkt vom IKEA OTA Server holen. Findige Entwickler haben dazu ein [[https://github.com/dresden-elektronik/deconz-rest-plugin/blob/master/ikea-ota-download.py|Python Script]] geschrieben. Mit Hilfe dieses Script werden alle auf dem Server vorhanden Files heruntergeladen. Das Beispiel für das Rollo sieht dann so aus ''10037585-5.1-TRADFRI-connected-blind-2.2.009.ota.ota.signed''\\+All TRÅDFRI components support Over-The-Air (OTA) updates. You don't need to worry about that, as it takes place in the background, for example through the gateway. However, if we want to flash the current firmware while reprogramming, we can also fetch the data directly from the IKEA OTA server. Resourceful developers have written a [[https://github.com/dresden-elektronik/deconz-rest-plugin/blob/master/ikea-ota-download.py |Python Script]]. With the help of this script, all files available on the server are downloaded. The example for the roller blind then looks like this: ``10037585-5.1-TRADFRI-connected-blind-2.2.009.ota.ota.signed'' \\
  
-Es wird allerdings nur der MAIN Bereich des FLASH aktualisiert. Die Bereiche USER, LOCK und CHIP ändern sich nicht und sind somit auch nicht online. Will man also ein Modul in eine andere Funktionalität umprogrammieren, so muss man es zumindest einmal selber ausgelesen haben um an die Daten für USER, LOCK und CHIP zu kommen.\\+However, only the MAIN area of ​​the FLASH is updated. The USER, LOCK and CHIP areas do not change and are therefore not online either. If you want to reprogram a module with a different functionality, you have to read it out yourself at least once in order to get to the data for USER, LOCK and CHIP. \\
  
-Die geladenen Daten sind in einem exotischen Format gekapselt mit der Abkürzung NGIS. Hier war auch wieder etwas Arbeit nötig um das Format zu entschlüsseln und die Binärdatei zu extrahieren. Eine tolle Unterstützung war dabei übrigens das Program [[https://www.synalysis.net|Synalyze it! Pro]]. Das Graph File liegt im Downloadbereich bereit.\\+The loaded data is encapsulated in an exotic format with the abbreviation NGIS. Here again some work was necessary to decrypt the format and extract the binary file. The program [[https://www.synalysis.net | Synalyze it! Per]]. The graph file is available in the download area. \\

- +For extracting I wrote a Python script that is also in the download area. In the previous tests, the extracted version was binary identical to the one that was read out. \\
-Zum Extrahieren habe ich ebenfalls ein Python Script geschrieben das auch im Downloadbereich liegt. Bei den bisherigen Tests war die extrahierte Version binäridentisch zur ausgelesenen.\\ +
