Different to the working procedure of 2.0 in OpenHD evo is a lot more versatile. But some advanced features are not exposed in QOpenHD or not automatically enabled.
We differenciate a little in the way that we do not automatically enable the wifi-hotspot. And we also do not stream Video/Telemetry over wifi, but use it mostly for our Webinterface to download Recordings, or debug and SSH-Access.
The username is openhd The password is openhd
To enable the Wifi-Hotspot you need to enable it in Air(TMP) or Ground(TMP) The standart IP for the SBC is 192.168.3.1. The password is openhdopenhd
Sometimes the user may override protection-features like the wifi-hotspot being able to share Video/Telemetry or force OpenHD to send Video/Telemetry to a specific IP. This can be done in the hardware.conf on the SD-Card.

In Passive mode, OpenHD's Ethernet is configured as a client, allowing you to connect it to a router or any device providing a DHCP server for seamless network integration.
Connect an Ethernet cable from your Linux device to the Single Board Computer (SBC).
Wait briefly.
Open a terminal and enter the command: sudo arp-scan --interface=eth0 --localnet (Replace ETH0 with the correct adapter connected to the SBC).
Test the connection by entering the SBC's IP address into your web browser; it should redirect you to the OpenHD web interface.
Record IP Addresses: Once connected, note the IP addresses of both devices:
SBC IP: For example, 10.42.0.118
Laptop IP: For example, 10.42.0.1
Configure Forwarding in OpenHD:
SSH into the RPI (user and password is openhd).Open the hardware.conf file located in /boot/openhd/ on your SBC. Modify the NW_MANUAL_FORWARDING_IPS IP address to point to your laptop’s IP:
This setup will ensure that video and telemetry data are directed to your laptop's IP, enhancing your tethered OpenHD experience.
Connect an Ethernet cable from your Windows device to the SBC.
Search for "View network connections."
Access the settings of the network connection providing your Windows device with internet access.
Click on "Properties" and "Share."
Select your Ethernet connection with the SBC.
Wait briefly.
Use a software tool to scan for devices on your system (recommendation: Angry IP Scanner) to locate active devices.
Test the connection by entering the SBC's IP address into your web browser; it should redirect you to the OpenHD web interface.
(Sometimes not needed) Edit the hardware.conf on your SBC and add the Windows IP address to the forwarding IP addresses (usually 192.168.137.1).
This mode charges your mobile phone from the SBC; please note that Raspberry Pi devices may sometimes fail to boot when a phone is connected.
Connect a suitable cable to your SBC; ensure it's a data-capable USB cable.
Go to your network settings, enable hotspot, and then enable USB Tethering.
All further configurations are done on the SBC.
For the best experience, use the official QOpenHD Evo app, available on the Play Store.
Some carriers and manufacturers may hide the tethering setting. If it's not visible due to the absence of a SIM card or other reasons, you may need to use a third-party app to enable it (recommended app will be provided later).
Connect a suitable Ethernet adapter to your Android device.
Go to your network settings, enable hotspot, and then enable Ethernet Tethering.

Active mode is designed for IP cameras or connecting peripherals to the Ethernet port that do not have a DHCP server. In this mode, the SBC runs its own DHCP server, allowing devices to connect directly.
Active mode does not support sharing internet with the SBC.
Using the Wi-Fi Hotspot in OpenHD Evo
⚠️ This documentation is outdated! A current version is available at
As of now, OpenHD Evo does not offer specific setup options for configuring the Wi-Fi hotspot. However, you can connect to the hotspot with the following default credentials:
SSID (Network Name): openhd
Password: openhdopenhd
Important Notes:
To use the web interface (webui) within the Wi-Fi hotspot, you must disable your mobile data connection on your device to ensure it connects to the hotspot correctly.
Warning: Using the Wi-Fi hotspot will not give you telemetry and video, but is only there for debugging and the webui.
Warning: Using the Wi-Fi hotspot may interfere with your overall communication range. Exercise caution and deactivate the hotspot when not in use to avoid impacting your connection to the drone.
# Specify additional IP address(es) for video and telemetry forwarding.
# OpenHD can detect external devices based on the connection and platform.
# Only applicable on ground units.
NW_MANUAL_FORWARDING_IPS = 10.42.0.1 # Replace with your Ground Station IP (laptop)
