The radio module firmware will try to integrate the multiple MAVLink packets to a wireless packet, in order to get the best efficiency. Connecting to APM 2. Links Forum Bazzar Blog Contact us. The largest radio module packet capacity is bytes. This article only covers the main difference between the two radios — connecting the radios. The latest version of the APM firmware can use this information to automatically match telemetry streaming rate to data rate maintained by the radio module. So as long as your antenna gain is below 10 dBi, you should have the provisions complied with the ISM.

The radio module packet contains the RSSI Received Signal Strength Indicator information on both ends tekemetry links, which can let the ground station or the plane take action when the Signal is not good. This page has been accessed 65, times. The other factor to select the data transfer rate is TDM “synchronization time”.
The graph below shows the ground and remote receiver strength vs distance from home in meters for a test flight of a 3DR Radio SiK implementation on a SkyFun plane. See the advanced setup page for detailed information on diagnosing range issues using telemetry logs. You cannot connect via the radios when your APM 2. It provides a significantly better range.
As the platform is open source, telemetty can be purchased from many different sources, including ArduPilot Partners:. You should get a value of over for a standard SiK radio.

Although anecdotal, another user provided a Tlog showing a good link kept while the vehicle was 4. The latest version of the APM firmware can use this information to automatically match telemetry streaming rate to data rate maintained by the radio module.
The 3DR Radio is the easiest way to setup a telemetry connection between your flight controller and a ground station. The disadvantage of ECC option is that it will halve the available bandwidth, but it’s worth it in the most situations, you can maintain the reliable links within a farther range. The meaning of the different LED states is: A SiK Telemetry Radio is one of the easiest ways to setup a telemetry connection between your Flight Controller and a ground station.
To connect the radios: The ground based radio was attached to a 3.
Regarding the power level, you must be very careful to deploy the radio module, and you should obey the legal authority limits of the country when operating. The Master collocates with long antenna and the Slave collocates with a short antenna to reduce the load of the aircraft. You should also read SiK Radio v2telemetgy contains a more detailed user guide and feature list.
The reason of placing duty cycle is that some parts of the world allow a higher transmission power or more frequency; your duty cycle can be used when it’s below a certain value. On a windows 7 or higher machine, the require drivers should be automatically installed the first time you plug in the ground module but if it does not install for some reason teelemetry the ground computer is running Windows XP or earlier you can get the Telemetgy FTDI driver here.
The radio uses open source firmware which has been specially designed to work well with MAVLink packets and to be integrated with the Mission Planner, Copter, Rover and Plane.
Many users will not need to configure their radios! Setup the two radios one meter apart and look at the local and remote RSSI. Please pay attention to Plus-n-Minus of the power supply, the chip and circuit telemwtry be burned if connecting the power supply inversely.
