Enabling monitor mode
Ways to prepare for receiving & sending data
For DroneBridge to work the WiFi adapter must be in monitor mode. You can set the cards to monitor mode using the following bash script (root privileges required):
interface='yourinterfacename'
ip link set $interface down
iw dev $interface set type managed
ip link set $interface up
iw dev $interface set bitrates legacy-2.4 54
ip link set $interface down
iw dev $interface set type monitor
ip link set $interface up
iw dev $interface set freq 2472
echo $interface
iwconfig
In DroneBridge the script
/startup/init_wifi.py is used to setup the cards. You may want to use it.
