-OSKR was "released" in october 2020, however, so far only an OSKR firmware is available and nothing else. You are able to SSH into an OSKR Vector, you can look around in the filesystem and the Yocto Linux and you are able to change some json configuration files. But everything else to create new functions or "plugins" for the robot as advertised by DDL on the Kickstarter ist still missing as of now (mid-march 2021neraly six months later), e.g. source code, documentation worth the name or dev tools or tutorials. I can only assume that DDL wants to sell their "Vector Boot Camp" and does not release the neccessary tools and informations because of that.+OSKR was "released" in october 2020, however, so far only an OSKR firmware is available and nothing else.

I can only assume that DDL wants to sell their "Vector Boot Camp" and does not release the neccessary tools and informations because of that. What was already released on Github is under a very restirctive license that not really qualifies as 2Open Source".

 For the Vector Web Setup you need Chrome as the browser (other webkit based browsers that support Web Bluetooth should work theoretically, but there are problems, Chrome is confirmed working) and a device that supports Web Bluetooth. Since desktop computers usually are not equipped with Bluetooth you may want to use a laptop, or buy a Bluetooth dongle for your desktop computer. Not all dongles may be compatible. I can confirm that this one works: **TP-Link UB400 Nano USB Bluetooth 4.0 Dongle** For the Vector Web Setup you need Chrome as the browser (other webkit based browsers that support Web Bluetooth should work theoretically, but there are problems, Chrome is confirmed working) and a device that supports Web Bluetooth.

 +===== The Big Bluetooth Mess =====
 +
 +Do not expect that this works for you. I have personally tried multiple Desktop computers and Laptops with Bluetooth dongles and inbuilt Bluetooth on Windows and Linux and it worked only repeatable und reliable on a Microsoft Surface Pro 3 with inbuilt Bluetooth. With all other platforms and OS combinations it sometimes worked on the first connection, but subsequent connections were not possible, even after doing more occult stuff as deleting devices in Chrome Bluetooth settings.
 +
 +This mess is so gigantic that DDL decided to ditch Web Bluetooth for Escape Pod and instead relying on the Bluetooth that comes with a RasPi 4 for connecting to the robots.
 +
 +Because of that I would expect for the future that DDL will make the use of a RasPi 4 for flashing an OSKR OTA onto the robot mandatory, since the possible combinations of platforms, OSes and Bluetooth devices will make it nearly impossible for them to write code that will work on all of them. That is most probably also the cause why they do not offer Escape Pod for other Linux flavours or for Windows. Or to say it short: DDL bit off more than they can chew and thus search for easy ways around that (easy ways for them, not for the users).
