Hi,
I am working on custom board which has nrf9160 as modem and stm32 as host controller.
here I am used lwip stack on stm32 controller to get the IP address.
I have NB-IoT SIM card on nrf9160 and I am trying to get IP address from it.
Now the issue is while using LWIP stack I am not the IP address.
Here I am attach the logs form LTE network which get the IP address from LWIP stack using PPP on Quectel Modem.

when I used NRF9160 modem I am not able to IP address from same LWIP stack using PPP.
here is the logs when I used NRF9160 as modem (application used in nrf9160 Serial LTE modem (2.5.0)).
