CRSF
Connectivity
with
flight
controller
(COLIBRI)
Getting
either
of
our
two
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
Taranis/OpenTX
and
BetaFlight
FC)
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).
The
CROSSFIRE
receiver
(firmware
1.59
and
later)
comes
our
latest
digital
CRSF
V2
(
CR
os
SF
ire)
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
or
higher,
CleanFlight
to
follow
soon
•
Taranis
or
X
Q7
radio
with
OpenTX
V2.2
or
later
•
TBS
CROSSFIRE
with
BETA
V1.62
or
later
(transmitter
and
receiver)
•
JST-SH-to-Servo
cable
to
connect
FC
UART
to
CROSSFIRE
