Good day everyone,
I can access the PPP mode by executing ATD*99# on the UART port of my EC200U module and successfully send UDP packets
But here’s the problem, when I disconnect the antenna to test whether the disconnection from the LTE network is handled correctly, unfortunately nothing is detected. I can send UDP packets and the PPP packets indicate that everything is working as it used to be, but it’s not. It’s disconnected from the LTE network but there seems to be no packet or indicator that the network is down.
Is there any way to detect disconnection from the LTE network while in PPP mode? Thanks a lot
