Through the Blueye App, it is now possible to change the Wi-Fi settings on the Surface Unit. If you can't remember the password for Surface Unit, simply press the reset button under the blue rubber lid once to reset the password. Press and hold the reset button for 15 seconds to reset all settings including the SSID (Wi-Fi name) on the Surface Unit.
The available settings are:
For a more detailed explanation of each of the settings see the bottom section of this article.
Where to find these settings:
Navigate to the Surface Unit settings by tapping the Settings icon on the bottom bar, and tap "Surface Unit Settings" when your device is connected to the Blueye Surface Unit Wi-Fi network.
You can change one or more settings at once by entering the new settings and tapping the "Save and Apply" button. The interface is shown in the figure below.
After "Save and apply" is tapped, your Surface Unit will apply the settings and restart the Wi-fi network. Now your device might automatically connect to your home network since the Blueye network disappears for a short while. If you change password or SSID, you have to enter Settings, and then Wifi on your device and wait for the new network to appear. This can take up to 1 min. The Apply screen is shown below.
Once connected to the new network, jump back to the Blueye App and wait for the complete screen to appear. You have now successfully updated the settings on the Blueye Surface Unit. The complete screen is shown below.
Resetting the Surface Unit to factory settings
To reset the Surface Unit Wi-Fi password to 1234567890, simply push the reset button under the blue rubber lid, between the two antennas, for 1 second. To make a full factory reset push and hold the reset button for 15s while the device is powered on. Once the button is released the LEDs will now blink back and forth while the unit is resetting. The Surface Unit will then reboot automatically with the SSID and password as marked on the back of the Surface Unit.
Explanation of the Surface Unit settings
Wi-Fi SSID is the name of the Wi-Fi network and WPA key is the password for the Wi-Fi network. It is recommended to set a new password since all drones have the same password initially (1234567890). This is the simplest way to protect the video files that are stored on the drone, and limit access to who can control the drone since the Blueye app is publicly available. However, you can always click the reset button on the Surface Unit, and it will reset both SSID and WPA key.
By setting the correct country you are in, you let the Surface Unit automatically find the allowed and most available channel. The Surface Unit will search for available channels during boot.
Selecting Wi-Fi Frequency and Bandwidth
Wi-Fi frequency has two options; 2.4 GHz and 5 GHz. We recommend using 5 GHz for faster transfer speeds while streaming the video. 2.4 GHz does have a longer range, at the cost of lower speed. But if the 5 GHz band is very crowded or you want to maximize the range of the Surface Unit, then you will be better off with 2.4 GHz.
Bandwidth is the width of the frequency band that the Wi-fi signals are using. Selecting 40 MHz will take up more of the available bandwidth for other Wi-Fi networks, but it will give you a more stable and faster network. The 20 MHz option will take up less space but has a slower data transfer rate. If you are diving out in areas away from other Wi-Fi networks, 40 MHz is the recommended setting. See illustration below showing our Blueye Surface Unit in red, with 40 MHz bandwidth and 5 GHz frequency selected, together with other networks in the area.
