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. As this radio is no longer available from 3DR, the page has been renamed to reflect the underlying open source radio platform. Introduction The 3DR Radio telemetry system is designed as an open source Xbee replacement radio set, offering a lower price, longer range and superior performance to Xbee 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. This article only covers the main difference between the two radios — connecting the radios.
MAVLink protocol framing and status reporting. The 3DR Radio telemetry system is designed as an open source Xbee replacement radio set, offering a lower price, longer range and superior performance to Xbee radios. 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.
3DR Radio v1 — Copter documentation
Setup the two radios one meter apart and look at the local and remote RSSI. Open the Mission Planner and you will see the interface below: Please pay attention to Plus-n-Minus of the power supply, the chip and circuit would be burned if connecting the power supply inversely.
Many users will not need to configure their radios! 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 or the ground computer is running Windows XP or earlier you can get the D2XX FTDI driver here.
The radio module firmware will try to integrate the multiple MAVLink packets to a wireless packet, in order to get the best efficiency. It provides a significantly better range.
The radio module packet also contains the information of the error rate and serial transmission buffer being enough or not percentage. It can only support the power levels in the table below.
Join in on the forum to help make these radios even better! It is very important to clear the statutory frequency of different country or region, frequency hopping channel, power rating; 3DR radio module can be configured correctly and in accordance with your local regulations. The graph shows the vehicle reached a distance of nearly 3km and the link was completely maintained throughout the flight.
3DR Radio Telemetry Module
You need to know the local signal level regulations of the radio module with LBT function. Views Read View source View history. Move the board and you will see the parameter change in the area below, which indicates the communication between the radio telemetry modules is good.
The best place to get involved with the development or tuning of these radios is the SiK Radios forum.
This page was last modified on 14 Marchat Red LED blinks – Data transmission. This program synchronization with other radio module just needs a few seconds to transfer when it’s at a higher data transmission rate, but if using a low transmission, the rate is slower.
One case where you might do so is when you use your vehicle with others — in which case you will need to specify different radio channels Net ID. The plane used a small omni antenna, and a 8dB patch antenna on the ground station. The principle is to change receive channel slowly while rapidly change the transmission channel.
