Configuring ROSbot to work with 5GHz WiFi.
By default ROSbot supports WiFi in 2.4GHz band, this is sufficent for most cases. If you encounter
problems with data transfers e.g. due to processing large amounts of data or noise from other
networks you can try to use connection in 5GHz band.
To do this, you will need a USB 5GHz WiFi card (any device based on rtl8812au should be fine, tested
models are TP-Link Archer T4U and D-Link DWA-172)
If you have recent image version you can skip update and kernel instal, otherwise do:
sudo apt-get update
This will update packages list.
Then do:
sudo apt-get install tinkerboard-kernel
This will install the newest available kernel version, that supports 5GHz WiFi.
Load kernel module:
modprobe rtl8812au
Type ifconfig to list network interfaces. You should see now new interface named wlan1
Now, You can list all available newtworks:
sudo iwlist wlan1 scanning | grep ESSID
You can connect to your WiFi with:
nmcli d wifi connect <ESSID> password <pass> iface wlan1
Remember to replace ESSID and pass with name and passowrd of chosen network.
ROSbot will try to connect to this network each time it boots.
