Hi,
I trying observe the dial up procedure of LTE modem when test with LTE emulator.
I see modem connect to eNB after power on (MAC layer UP).
At this moment, I do not input any AT command yet.
Then, I start sniffer frames on LTE emulator and input AT command to bring up IP connection to LTE emulator.
The ppp0 appear on device with a IP assigned by LTE emulator.
But I do not see any related frames.
Have anyone know what modem will do to bring up IP layer after receive AT commands?
Or where I can find related documents or information?
Thanks.
Ricky
