Hi Will,

There is a Pull Request that implements the use of real GPS data for the asset_tracker sample.

Note that you need the latest modem firmware.
It can get GPS data while the device is in PSM mode.

When testing GPS I would recommend using an external antenna as described here for best performance.

If you have the v0.8.5 or newer of the DK you can use the on-board GPS antenna.

Hi there, following up on this thread cause I have the same question. With the new firmware (v1.0), are we able to use GPS +LTE-M/NB-IoT concurrently or do we have to cycle between them? Do we need a dedicated antenna? Also, would you be able to walk me through where and how to enable GPS to capture real data through the asset_tracker sample?

Hi Noobie,

The Modem firmware that is available now does not support GPS +LTE-M/NB-IoT concurrently.

You need to switch the modem to offline mode (with for example AT+CFUN=4) and then select the other network mode (with for example AT%XSYSTEMMODE=<>) and then turn on the modem again.

So let's say you turn on the GPS capture the data, turn modem to offline mode then switch to LTE-M mode and then send the data to nrf-cloud similar to how it's done in the asset_tracker sample.

Best Regards,

Martin L.
