RE: PCA 10090 versions 0.8.2 vs 0.8.5

Hi Lachim,

1.) There should not be any difference in running the software on the two boards. (They use the same nRF91 SIP version) You most likely have two different modem firmware versions on the boards. Please make sure to use the latest mfw on both DKs: https://www.nordicsemi.com/Products/Low-power-cellular-IoT/nRF9160/Download#infotabs

2.) I would recommend using the version at tag v0.4.0 (tagged releases are known as stable)

#How to get tag v0.4.0
cd ncs/nrf
git checkout master
git pull
git checkout v0.4.0
west update

3.) For the modem version that is out now you need to switch off the modem (AT+CFUN=4) then switch to GPS mode (AT%XSYSTEMMODE=0,0,1,0) and then turn on the modem again, and then gather the GPS data.

(Future modem firmware will make this a lot easier, but as for now this is how you can acquire real GPS data)

4.) We have the drivers for peripherals ready. This is called for example "spi_nrfx_spim.c" for the SPI master driver. (notice the nrfx)'

For the GPS the API is not 100% ready yet, but you can test it out and play around with the GPS sample.

5.) For nRF91 Development using the Nordic Connect SDK, you are recommended to use the SES version which is linked to in the "Getting Started Assistant" app in the nRF Connect for Desktop.

(it is marked with "nordic edition" in the top bar)

6.) That is something that may be possible to do. I would recommend you to contact your RSM with regards to this. (if you do not know who that is please send me a direct message on Devzone and I will help you out)

As for Guides etc. we have made some Getting started guides: https://devzone.nordicsemi.com/nordic/cellular-iot-guides/b/getting-started-cellular (which I highly recommend taking a look at)

and some "Hardware" guides: https://devzone.nordicsemi.com/nordic/cellular-iot-guides/b/hardware-design
