Hi everyone, We’ve just released a new stable version of the Companion software! 😃 For a formal summary check the [release notes](https://github.com/bluerobotics/companion/blob/master/release-notes.txt#L174-L183), but here are the main points explained: - Reduced CPU usage (should reduce/fix video dropouts/poor quality) - Fixed bug stopping the heartbeat failsafe from working correctly - Fixed bug causing [missing Wifi SSIDs](https://discuss.bluerobotics.com/t/can-not-find-wifi-network/9996) (\*see below) - change default waterlinked underwater gps hostname from `waterlinked.local` to `192.168.2.94` # Normal Update If you don’t have missing wifi SSIDs you can update as usual from the [System page](https://192.168.2.2:2770/system) of the [companion web interface](https://www.ardusub.com/reference/companion-web-ui.html) > **NOTE** : this update updates the mavproxy library so will generally take ~20 minutes to complete (expect slow progress on the `arm-linux-gnueabihf-gcc` lines). If your ROV enclosure is accessible, it may be faster to download and directly [flash the image onto the Raspberry Pi SD card](https://www.ardusub.com/quick-start/installing-companion.html). # Missing Wifi SSIDs The missing wifi SSIDs issue was caused by a problem in the update process from the 0.0.22 release, so to fix it requires either: 1. Directly [flashing](https://www.ardusub.com/quick-start/installing-companion.html) a more recent image (than 0.0.22) onto the Raspberry Pi SD card (requires opening the enclosure) **OR** From the companion web interface Git page ([https://192.168.2.2:2770/git](https://192.168.2.2:2770/git)): 1. Select the desired remote, **local** for Blue Robotics repository. 2. Click in **tags** to open the available options. 3. Select the **0.0.21** tag, it’ll be highlighted when selected. 4. Click **Update** to perform the roll back ![git-update-wifi-SSID-fix](https://us1.discourse-cdn.com/flex019/uploads/bluerobotics/original/2X/a/a0e9e438fe7df2b93533a4c33acd2b0da895325a.png) 5. Connecting to your wifi network using the [Network page](http://192.168.2.2:2770/network) (if not already connected) 6. Updating with the normal ‘Update’ button from the [System page](http://192.168.2.2:2770/system) ---

Hi! Regarding Waterlinked there is an old bug with Waterlinked Gen2. Willian has helped me with a temporary solution hacking the 0.0.26 script to hardwire Companion Waterlinked script to 192.168.2.94 instead of name resolution. Since I do not see that in release note for 0.0.27 I guess that problem persist? Btw @EliotBR if you talk to Willian, I think my resent mails to him is caught in BR mailfilter, please ask him to contact me… ---

That’s now fixed in 0.0.28, along with some other minor updates of stuff that got missed in the 0.0.27 update. @gcelec you should be good to update your Water Linked ones now too 🙂 ---

I want to integrate [Water Linked DVL A50](https://store.waterlinked.com/product/dvl-a50/) into BlueROV2. When I access [https://192.168.2.2:2770/git](https://192.168.2.2:2770/git), I accidentally delete **orign**. Is there any way to restore it? ---

Hi @yuki, Please update to [Companion 0.0.31](https://discuss.bluerobotics.com/t/companion-0-0-31-update-dvl-merge/11143) - DVL functionality is now merged into the main Companion software, so you shouldn’t need to install/enable it via git. For reference, it’s possible to add additional remotes via the [Git page](https://www.ardusub.com/reference/companion/git.html) (which you were on), by adding a name and repository link 🙂 ---
