Limitations

GNSS, AGPS, and modem DFU are not part of the generic sockets. Therefore, operating on them using poll is not possible.

PDN sockets only support open, close, setsockopt, and getsockopt to configure a PDN with an APN name. Therefore, there is no data communication on the socket, and it is not pollable.

Modem firmware limitations

For a detailed description of limitations related to the modem firmware used, refer to the changelog of that specific version. The changelog is distributed as part of the downloadable zip file.
