IGT-20 Persistent Tethering of WiFi

By default, IGT-20 manages networking with connmanctl. One can use the following command, assuming that WiFi has been enabled, to enable tethering of WiFi on IGT-20.

connmanctl tether wifi on <SSID> <PassPhrase>

However, the tethering won't be enabled by default automatically after IGT-20 reboots or connman service restarts, for connman disables tethering by default after its service restarts. To make IGT-20 persistent tethering WiFi, please create a configuration file named main.conf with the following content:

[General]
PersistentTetheringMode=true

And put this main.conf in /etc/connman. Then it works.
