Hello everyone, I have a BlueROV2 with a Ping sensor attached, but I’m having trouble retrieving the Ping data. The sensor is not detected in the PingViewer application. Additionally, I am unable to access the BlueOS via `blueos.local` (or `192.168.2.2`), even though I can successfully ping `192.168.2.2`. ![local host](https://us1.discourse-cdn.com/flex019/uploads/bluerobotics/original/2X/b/b5a0183be4c4b085e8f76e07523ec9006bd2ed54.png) Here are the steps I’ve taken so far: - Configured the network on my laptop according to the setup guide. - Checked the connections and ensured that the Ping sensor is properly attached. Despite these efforts, I still can’t access the BlueOS web interface or see the Ping data in PingViewer. I’m wondering if I need to modify any parameters in the QGroundControl (QGC) parameter list to get the Ping sensor working properly? ![Detected devices](https://us1.discourse-cdn.com/flex019/uploads/bluerobotics/original/2X/d/d814639ca289206739c4662294f46f21e24de6b0.png) Any advice or guidance on how to troubleshoot this would be greatly appreciated! Thanks in advance! ---

Hi @GLV13 Welcome to the forums! It looks like you’re using an older BlueROV2 with Companion OS, which is no longer recommended / supported. I would not expect the BlueOS interface to load as a result! You’ll need to remove your SD card and [flash it with BlueOS](https://blueos.cloud/docs/blueos/latest/installation/), and then things should work as expected once you complete the [vehicle setup.](https://bluerobotics.com/learn/bluerov2-software-setup/#update-software) ---

Thanks for the reply @tony-white . How to make sure that my ROV is running on Companion OS instead Blue OS. And, Is there a way that we can upgrade the OS without removing the electronic enclosure. ---

If you took that screenshot @GLV13 , then you are running Companion OS. That interface is loaded at 192.168.2.2:2770. To update, you must open the electronics enclosure to retrieve the MicroSD card from the Raspberry Pi - this is easiest to do by removing the two bolts that attach the camera mounting plate to the standoffs, you can then easily remove the MicroSD card…
