Hello I was working on my BR2 today, it opened in Cockpit, then I lost all coms/video stream , (and Blue OS not able to connect). I tried two other tethers and spare computers, but all same result , then tried my spare BR2 and that connected without a problem , so not a tether or computer issue. W…

It’s always worth pulling the housing off and connecting an Ethernet cable from the Pi directly to your computer. If it works, you’re problem is the tether/slipring/Fathom board/box, etc. If it’s still not talking, we find corrupted or loose SD flash card is the most common fault, so maybe flash a…

hello peter thanks , do you mean to disconnect the lan cable from the navigator board and then connect a lan cable from the navigator board straight to my laptop and disconnect the Fathom USB cable ? If yes I tried that and replaced the SD card , but still no activity , I have never seen this ty…

Hi @Mac1 - Do you know what version of BlueOS you were using? When you say all lights are flashing normally, can you better explain what you observe? You should have a flashing blue light on the navigator, and a small (occasionally) flashing green light next to a solid red light on the Raspberry …

Yes, that’s the idea. You go from the Raspberry Pi directly to the laptop. with an 8 wire Ethernet cable with RJ45 connectors (standard Ethernet cable in a LAN). But of course you must remember to change the laptop’s Ethernet adaptor settings, but first changing the IP address assigned to the Fat…

Hello Tony , please see pictures of the navigator lights and the PI , also the other side electronic board ( I have disconnected the upper sonar electronic board, until I can resolve my issue ). [2c467239-2947-4892-87aa-49aa230f5b70] [d253825d-5a31-406f-a004-21d0cc65c4de]

Hi @Mac1 - Do you not have any blinking lights on the ethernet switch indicating traffic? The ethernet switch could be having problems, tough to tell from the picture. The suggestion of plugging an ethernet cable straight from computer to Raspberry Pi is a good one, as it shows the issue is likely …

Navigator lights = flashing blue status light, solid 5V blue light , solid 3.3 v green light on the other side a solid yellow PWR light Is this the correct link to download and flash onto the SD card ? ARMv7 (32-bit) Bullseye Sometimes when I connect cockpit I am able to connect through wifi , b…

Hello I somehow managed to get things back working , re flashed the SD card again and played about with video sources. I have a couple of things now needing sorting :slight_smile: camera tilt is not working on the BR camera , all settings are still correct in the joystick settings , buttons sho…

Hi @Mac1 - Glad you got things sorted. If your camera tilt servo is connected to the default channel 16, then in BlueOS on the vehicle setup page , PWM outputs , you should see that function next to channel 16. Please share a screenshot. Simply edit the JS_Gain_Steps parameter in BlueOS under Aut…

Hi Tony , thanks , got the camera and gain steps sorted . How do you re calibrate the sensors , and then save them for future Also i have downloaded ping viewer into BlueOS, I now have ping sonar device and ping viewer next , which one should be active and how do I create a widget in Cockpit for …
