nRF9160: TCP/IP Server-Client with BSD library

Hi,

Finally i am able to build a basic TCP/IP server client, attaching the project heretcp_client_server.zip, i have some questions wrt modem and TCP/IP stack:

  • I see two different socket calls nrf_xxx and and plain bsd apis, which one i should  use? or it doesnt matter what even API I call?
  • Since I am using modem TCP/IP stack I can put my M33 core in sleep/low power mode, so in this scenario when I have listening socket and a there is an incoming connection can the modem wakeup the core to handle the connection?
  • If i want to use the nrf91 as a serial lte modem how can i realize the functionality of RI, DSR, DTR?
  • Can I the create a secured socket with ssl/tls with modem TCP/IP stack? if so please point me to an example, note that i dont want to run the ssl layer on the M33 core it will increase my over all current consumption.

regards

KK
