Hello Fellows,
how can i check that an internet connection is present - primarily on the device - passively, beside any active approach that tests the connection by ping or udp/tcp connect...?
Depending on the settings, testing the connection may initiate to open a connection ( i.e. dial up), which i want to avoid especially on the device due to certain concerns like costs etc. ( the connection testing will consume some traffic over time = costs).
I'm sorry if that question has already been answered, my search was not successful.
regards,
