using nRF52 with nRF91 SLM

[jonas.woerner]

Hi,

Im just starting to use the nRF9160 with the SLM application flashed. All the samples and articles I found were always using stuff like the LTE link control library or some modem library that I cannot directly access with the nRF52,  so I hope someone has the answers im looking for here:

Im using the nRF9160-DK with the nRF91 flashed with modem fw and SLM, and the nRF52 running my own application.

• How can I check what network im connected with currently?
• Do I need to handle connection loss, or is it handled by SLM?
• how can I get informed about network changes, like changed cell ID, disconnected event, etc.
• Is it possible to manually send AT commands while the driver is using the nRF91?
• How can I save power? I cannot use the lte link control library, so how would I shut down the modem / reconnect or use power saving functions?
• Is there an easy way of using peripheral devices that are connected to the nRF91 on the nRF52? for example the sensors connected on a thingy:91?

kind regards,

Jonas

Hello Jonas, 

Are you running a custom application on the nRF52840 found on the nRF9160DK? The nRF9160 DK contains an nRF52840 SoC that routes some of the nRF9160 SiP pins to different components on the DK, such as LEDs and buttons, and to specific pins of the nRF52840 SoC itself. Have a look at the Board Controller firmware documentation for more information.

In order to communicate with the Serial LTE Modem you can use an external MCU on another DK, i.e. nRF52840 DK. More information can be found under Communicating with the modem on an nRF91 Series DK.

Kind regards,
Øyvind

yes im running a custom app on the nRF52 on the nrf9160DK... This is working fine in general.
