Crazyradio

The cr command provides direct access to the Crazyradio dongle for operations that do not require a connection to a Crazyflie. This includes listing connected dongles, sniffing radio traffic and broadcasting packets.

Listing Crazyradios

To list all connected Crazyradio dongles:

cfcli cr list

This will show information about each dongle including serial number, firmware version and USB bus location.

Sniffing packets

To sniff broadcast packets on a given channel and address:

cfcli cr sniff

By default this listens on channel 80, datarate 2M and address E7E7E7E7E7. These can be changed with the --channel, --datarate and --address options:

cfcli cr sniff --channel 78 --datarate 2 --address FFE7E7E7E7

Received packets are printed with pipe, RSSI, timestamp and payload data.

Broadcasting a packet

To broadcast a packet (without acknowledgement) on a given channel and address use the broadcast subcommand. Data can be provided either inline or from a file.

Inline data

Provide bytes as a comma-separated list using --data. Both decimal and hexadecimal (prefix 0x) values are supported:

cfcli cr broadcast --data 0x8F,0x07,0x00,0x00,0x00,0x00,0x3F,0x00

Data from a file

Provide raw binary data from a file using --input (or -i):

cfcli cr broadcast --input packet.bin

Options

All broadcast options with their defaults:

Option	Description	Default
--radio, -r	Crazyradio index (0-based)	0
--channel, -c	Radio channel (0-125)	80
--datarate, -d	Datarate: 0=250K, 1=1M, 2=2M	2
--address, -a	5-byte broadcast address (hex)	FFE7E7E7E7
--data	Comma-separated bytes to send
--input, -i	File to read raw binary data from

Either --data or --input must be provided.
