These directories provide examples that are specific to u-blox cellular modules, e.g. SARA-U201, SARA-R4 and SARA-R5. For basic things, e.g. powering up a cellular module, using a cellular module for sockets/TLS or MQTT or CellLocate or security or using a GNSS module that is incorporated into a cellular module etc., you should refer to the generic examples instead; the APIs demonstrated here are only those specific to certain aspects of cellular behaviour, hence requiring use of the cell API directly.
- lte_cfg contains an example of how to configure an LTE cellular module (e.g. SARA-R4 or SARA-R5) to obtain network service in exactly the way you like using
ubxlib. If you are having trouble getting network service or you want to learn how to programmatical configure the cellular network settings, this example may be of use to you. - power_saving contains examples of how to configure a cellular module for 3GPP power saving and E-DRX (also a form of power saving).
