nRF Cloud AGPS Sample

Important: this sample is outdated and no longer exists in future versions of nRF Connect SDK

The nrf_cloud_agps sample is the easiest way to get started with generating GPS coordinates with your nRF9160 Feather.

Precompiled Binary

Note: you can get a pre-build binary file compiled previously using NCS v1.3.2 here.

Programming nrf_cloud_apgs Sample

  1. Change directories to ncs/nrf (Make sure you're using NCS v1.4.0 or newer.)
  2. Then change directories to /nrf/samples/nrf9160/agps/
  3. Add this to prj.conf: 
    # Cloud prefix for nRF9160 Feather
CONFIG_NRF_CLOUD_CLIENT_ID_PREFIX="feather-"

# Image manager
CONFIG_IMG_MANAGER=y
CONFIG_FLASH=y
CONFIG_IMG_ERASE_PROGRESSIVELY=y

# Enable Zephyr application to be booted by MCUboot
CONFIG_BOOTLOADER_MCUBOOT=y

# COEX0 is used to enable the GPS LNA, but it has to be configured to do so.
CONFIG_NRF9160_GPS_SET_COEX0=y
CONFIG_NRF9160_GPS_COEX0_STRING="AT%XCOEX0=1,1,1565,1586"

Then compile as normal:

west build -b circuitdojo_feather_nrf9160ns

Note: having trouble building? Make sure you check out the troubleshooting page.

Then load using newmgr:

newtmgr -c serial image upload build/zephyr/app_update.bin
newtmgr -c serial reset

Setting Up nRF Connect for Cloud

During factory test, your nRF9160 Feather is added to nRF Connect for Cloud for your immediate use! The only thing you'll need, other than your nRF9160 Feather, SIM and antenna is your getting started card:

Cloud Code

Every nRF9160 Feather has a device ID generated based on the IMEI. Your full device ID will look something like:

feather-<IMEI> where <IMEI> is the IMEI tied to your specific device.

Note: You can get the IMEI by running the AT+CGSN=1 command in LTE Link Monitor while running the at_client, default factory firmware or other firmware with AT Commands turned on.

Here are the steps to get you the rest of the way.

  1. First, program your device with the nrf_cloud_agps sample.
  2. Then, power up and confirm that the device can connect to the cloud.
  3. Create an nRF Connect for Cloud Account Add new device
  4. Once created, go to the top left and click the big + icon. Add LTE device
  5. Then skip the iBasis setup since we're using Hologram. Skip iBasis
  6. Enter the Device ID and the PIN provided on your card. Enter device ID and pin
  7. Once you press Add Device, nRF Connect for Cloud should notify you that your device has been added!
  8. Navigate to Devices and click on the device you're working wtih! Devices

That's it!

Your device screen will adapt to the example code that you're using. For example, it should display a map when you begin to publish GPS data.

Troubleshooting

There are some things that can go wrong here. They're usually related to your nRF Cloud certs.
