CRSF Connectivity with flight controller (COLIBRI)
Getting either of our CROSSFIRE receivers connected to the flight controller (BetaFlight/COLIBRI) through
our CRSF serial protocol enables you to have the most accurate and low-latency remote control possible
on the market. By integrating the CRSF protocol end-to-end (currently supported on TBS TANGO,
Taranis/OpenTX, BetaFlight FC, KISS FC and INav) allows you to make the full use of the new bidirectional
protocol.
In addition to a wide range of telemetry data about the uplink, downlink and the model itself via our BST
protocol, the CRSF protocol also supports remote changes of the flight controller settings (BetaFlight, KISS).
The CROSSFIRE receiver (firmware 1.59 and later) comes our latest digital CRSF V2 (CRosSFire) protocol. It
has the following advantages:
• R/C data transferred at high speed serial format
• Up to 150Hz , 3x faster than SBUS
• Lower latency
• CRC protection (error detection)
• Bidirectional communication, telemetry capable
• Changing settings remotely (via OSD or LUA scripts)
Minimum requirements
To get started, the system requires the following prerequisites:
• Flight controller (COLIBRI FC) with one free UART port (no inverter)
• Betaflight V3.1, INAV 1.7, KISS or higher, CleanFlight to follow soon
• Taranis etc. radio with OpenTX V2.2 or later, TBS TANGO
• TBS CROSSFIRE with BETA V1.62 or later
