Then Setting-up the device for ADB Steps are same as step 1 and 2 in `Generate a bug report` instruction: {% embed url="" %} #### Enable Multiple Video Stream via ADB Connect controller unit to computer via ADB and run > adb shell setprop persist.multiple.videostream true\ > \ > adb reboot Then repeat on air unit. Both of them need the setprop set. The video stream will be available at these 2 addresses > rtsp\://(wifiIPongcs):8554/fpv\_stream\ > rtsp\://(wifiIPongcs):8554/fpv\_stream1 #### Notice 1. Ensure something valid is connected to HDMI1 also, otherwise HDMI2 will not work. 2. Ensure [cooling fan](https://docs.cubepilot.org/user-guides/herelink/herelink-faq#herelink-airunit-fan-installation) is connected, else the air unit will be overheated. #### Disable Multiple Video Stream To disable and restore the setting, connect the unit to computer via ADB and run > adb shell setprop persist.multiple.videostream false\ > \ > adb reboot ## Why aren't the LEDs lit, even though the rover unit are correctly connected? Check the power input. It should be 7V - 12.6V max (3s Lipo supported) and the battery should be charged. ## Why can't I connect to 2.4GHz WIFI? Currently, the Datalink only enables 5.8GHz WIFI for internet connection. Therefore, to load maps, you will need to connect to a 5.8GHz WIFI network.
