NRF91 modem firmware and GPS AT commands

[julienh]

Hi,

We are planning to use a NRF51 + NRF91 but we want to avoid maintain 2 custom firmwares. To avoid that, we want to use an LTE-M module with precompiled firmware. 

I don't see any AT commands related to GPS. Are you planning to release a precompiled firmware for NRF91 on which we would be able to read GPS position using AT commands ? 

It's something which is available from a lot of other manufacturer and I'm sure that it can be useful for a lot of customers. 

Thank you

Hi,

 The modem does not expose the GPS functionality through AT commands. Instead, it is exposed through a socket API in the nrf_modem_lib (former bsdlib).

 

Are you planning to release a precompiled firmware for NRF91 on which we would be able to read GPS position using AT commands ? 

 We already have, at least for the nRF9160DK and the Thingy:91.

While the modem doesn't provide AT commands for the GPS, we have the Serial LTE Modem application which implements AT commands for networking and GPS on the application core.

You can find a pre-compiled version of the SLM for the DK here: https://www.nordicsemi.com/Software-and-tools/Development-Kits/nRF9160-DK/Download#infotabs

(GPS support might not be enabled in the pre-compiled files, as it is disabled by default in NCS v1.5.0. You can enable GPS support by adding CONFIG_SLM_GPS=y to the prj.conf file and building it yourself)

Though depending on your HW and usecase, you might want to compile it yourself with your own configuration and device tree files.

We are planning to use a NRF51

 Just a note, we don't recommend using the nRF51 for new designs, but rather one of the SoCs from the nRF52 series.

Best regards,
