os_is_network_connected()
Returns: Boolean
With this function you can check and see if your device currently has an internet connection and it will return true if it does, or false if it does not.
NOTE: This function checks the internal device API that controls connections and so may return true if there is a bluetooth connection, a Wi-Fi connection, or even just a normal
network connection that permits internet access.
