How can the GNSS execution time be read?

[Magne Kværum]

In the release notes for mfw_nrf9160_1.3.2 it says
"This release is aligned with v2.1 of nRF91 AT command reference guide."
And new functionality:
"- Feature to output GNSS execution time in milliseconds since the last start. Output shows the time
that firmware has performed for GNSS signal searches, and that information can be used for
decision-making at the application level. This feature requires support from nRF Connect SDK GNSS
API."
I can not find anything in the AT command reference guide 2.1 on how to read this.

Hi Magne,

"This release is aligned with v2.1 of nRF91 AT command reference guide." is just general comments. The modem firmware provides AT interface and GNSS interface, nRF91 AT command reference guide only covers the standard AT command parts. For the GNSS service, an API library is provided for developers to use.

API documentation — nrfxlib 2.2.0 documentation (nordicsemi.com) mentioned that execution_time is supported from modem firmware v1.3.2.

Best regards,

Charlie

Found it. Struct nrf_modem_gnss_pvt_data_frame contains execution_time. Read with:

nrf_modem_gnss_read(&pvt_data,

                          sizeof(struct nrf_modem_gnss_pvt_data_frame),

                          NRF_MODEM_GNSS_DATA_PVT);
