SmartLink set includes everything needed to setup wireless communication for video, telemetry and control. A standard set contains:
SmartLink Ground module
SmartLink Air module
2x Air Module antennas
2x Ground Module antennas
Air module power cable
Ground module power cable
First of all, attach your antennas to the air module:
Then attach the power supply cable and autopilot telemetry cables:
Power supply goes to 5V DC connector
Autopilot telemetry cable goes to UART connector
What the air module should look like with power and telemetry cables connected:
Connect CSI camera to camera socket. Use a small sharp tool to unlock the crimp:
Put the FPC camera cable in and lock the crimp by pushing it. At this stage the setup should look as follows:
Connect HDMI camera if desired:
The setup should look as follows:
Attach antennas to the ground module:
By default, 5 dBi antennas come included in the set. Depending on your specific applications you might choose to use alternative antennas designed for 2.4 GHz band.
Connect your micro USB cable and power cable to the ground module as shown below:
Ground module supports any power supply source with a voltage ranging from 10V to 50V. We recommend to use 3S or 4S LiPo battery to power the ground module. The typical current for 3S battery power is around 1A at maximum power output.
Air module is 5V tolerant only. Peak current can be up to 3A, therefore make sure to provide a powerful, stable and reliable power supply to the air module. We highly recommend to use SmartAP PDB 5V output port to power SmartLink. SmartAP PDB has 5V at 5A max power output which powers SmartLink perfectly.
SmartLink system is compatible with any autopilot which has TTL UART telemetry port. For instance, it's compatible with:
Pixhawk series Autopilot
APM series Autopilot
other TTL UART telemetry port autopilots
For this demonstration we use SmartAP MAX Autopilot from Sky-Drones:
Connect telemetry cable to Radio port of the autopilot as shown below:
After completing the steps above you will have fully assembled air module. Before the first power up, make sure you have assembled air module and ground module as shown below:
Power up both ground module and air module.
Ground module has status LEDs which allows it to identify the current status of the system. The most important LEDs are RSSI:
Three RSSI LEDs blinking altogether: RF off
Three RSSI LEDs blinking in turn: Searching for pair
One, two or three LEDs solid: RSSI status, more solid LEDs equals better signal
The expected LEDs pattern is as shown below - blinking in turn and then all three LEDs solid:
First of all, check if SmartLink ground module has been recognized properly by your computer. You should be able to see it as Ethernet device. For instance, go to the command line and type
ifconfig for MacOS / Linux or
ipconfig for Windows:
You should see that one of the network adapters has an IP address in the range of 192.168.168.xxx. This means that SmartLink has been successfully discovered by your computer. Alternatively, you can check the configuration with Network Manager and / or assign a static IP address:
Another method to check that SmartLink is properly recognized by your computer is to ping it. Open the command line and type
ping smartlink.local. If you are able to see the proper response in the command line then it means SmartLink has been discovered by your computer.
SmartLink is configured with static IP address 192.168.168.100. For instance, if you're running SmartLink with Android which doesn't support Local DNS - please use static IP address for connecting.
In case you're unable to ping `smartlink.local` it might be a DNS problem. In other words, the operating system can't find the IP address' corresponding name. This might happen on some Windows platforms and is applied to all Android based platforms. Follow these steps to resolve it: Use IP addressing instead of DNS
Once you have everything connected and powered up you may start the ground station software. SmartLink is compatible with various popular ground control stations. In this demonstration we use SmartAP GCS by Sky-Drones. SmartLink is fully supported by SmartAP GCS. Start SmartAP GCS and go to
Settings in left hand side menu:
Enable the option
Autoconnect to SmartLinkas this will enable SmartLink to automatically connect.
After that, go back to the
World pane and click the
Connections button in the top right hand corner. You will see SmartLink connection added. If it's not added automatically, or it is missing completely, you may add it manually as shown below:
Open connection will be established and you should be able to see telemetry information at this step.
To set up the video click on the
Settings button of the one of the video widgets and select the desired source. For this demonstration we need to select
SmartLink Video 1 option:
After 1-2 seconds the video feed will appear and connection status will be set to
You can easily switch between full map and full video simply by tapping on the video feed you'd like to see in full screen:
Finally, the full setup looks as follows:
