Try to understand LED indication 2G_TX_ON and WWAN_LED_N

Hi,

my testapplication runs on a mangOH board, and it sends UDP packets to my testserver.
During the UDP connection, I don’t see LED activity on the 2G_TX_ON LED.
Any idea how I can test this LED activity?

If my mangOH system detects a working SIM, the WWAN_LED is always ON.
Even if it does not create an rmnet0 data connection, the LED stays ON.
So, what is the definition of this LED activity?

greetings,
