Real-time telemetry using app link
The transmitter has a wireless close range telemetry module built-in for easy telemetry distribution to a
PC, MAC, tablet or phone. TBS CROSSFIRE supports different modes for different use cases.
Note: This section is only applies if you are using the Standard TX. The Micro TX is not equipped with
Bluetooth module.
• OFF
○ Close range telemetry module is completely disabled and won’t show up if you search for
devices.
• MAVLink Emulator (MAV Emu)
○ This mode is recommended if you have any kind of GPS source attached over BST ( TBS
GPS, DJI NAZA over TBS BLACKBOX, MAVLink FC over TBS BLACKBOX, ET Vector). If this
mode is selected an FC is emulated inside the TBS CROSSFIRE transmitter. This gives you
the ability to track your copter/plane in real-time with any MAVLink capable app on your
phone (e.g. Droidplanner app ) or GCS on your PC or MAC (e.g. QGroundControl)
• TBS
○ Telemetry data is sent in JSON format if this mode is active. This option has been removed
in later firmware versions.
• Serial Bridge
○ This mode is used for serial bridge between your connected device and the receiver.
Please refer to the Serial bridge section for further information.
• MAVLink
○ This mode is used to pass MAVLink messages back and forth. Use this mode if you have a
MAVLink FC connected to the diversity receiver. Please refer to the MAVLink section for
further information.
Device pairing
Once the CROSSFIRE is up and running, go to the PC, MAC, tablet or phone’s pairing screen and look for a
new device called “Crossfire ####” in the list. Tap the CROSSFIRE entry and accept the pairing request. It is
now ready to be used with Droidplanner.
