nRF Cloud Multi-service¶
The nRF Cloud Multi-service sample is a minimal, error tolerant, integrated demonstration of the nRF Cloud, Location, and AT Host libraries.
It demonstrates how you can integrate Firmware-Over-The-Air (FOTA), Location Services, Alert and Log Services, periodic sensor sampling, and more in your nRF Cloud-enabled application.
It also demonstrates how to build connected, error-tolerant applications without worrying about physical-level specifics using Zephyr’s conn_mgr
.
Refer to the nRF Connect SDK's nRF Cloud multi-service Documentation for more details.
Requirements¶
Before you start, check that you have the required hardware and software:
- 1x nRF9151 Connect Kit
- 1x nano-SIM card with LTE-M or NB-IoT support
- 1x U.FL cabled LTE-M/NB-IoT/NR+ Flexible Antenna (included in the box)
- 1x USB-C Cable
- A computer running macOS, Ubuntu, or Windows 10 or newer
Don't have an nRF Cloud account?¶
To connect your device and use nRF Cloud services, you must create an nRF Cloud account:
- Go to the nRF Cloud portal and click Register.
- Enter your email address and choose a password.
- Click Create Account.
-
Check for a verification email from nRF Cloud.
Tip
If you do not see the verification email, check your junk mail folder for an email from
no-reply@verificationemail.com
. -
Copy the six-digit verification code and paste it into the registration dialog box.
Tip
If you accidentally closed the registration dialog box, repeat Step 1 and click Already have a code?. Enter your email address and verification code.
You can now log in to the nRF Cloud portal with your email and password. After logging in, you can see the Dashboard view that displays your device count and service usage.
Set up your board¶
- Insert the nano-SIM card into the nano-SIM card slot.
- Attach the U.FL cabled LTE-M/NB-IoT/NR+ Flexible Antenna.
- Connect the nRF9151 Connect Kit to the computer with a USB-C cable.
Building the sample¶
To build the sample, follow the instructions in Getting Started Guide to set up your preferred building environment.
Use the following steps to build the nRF Cloud Multi-service sample on the command line.
-
Open a terminal window.
-
Go to
NCS-Project/nrf9151-connectkit
repository cloned in the Getting Started Guide. -
Build the sample using the
west build
command, specifying the board (following the-b
option) asnrf9151_connectkit/nrf9151/ns
.west build -p always -b nrf9151_connectkit/nrf9151/ns samples/nrf_cloud_multi_service -- -DEXTRA_CONF_FILE="overlay-http_nrf_provisioning.conf"
The
-p
always option forces a pristine build, and is recommended for new users. Users may also use the-p auto
option, which will use heuristics to determine if a pristine build is required, such as when building another sample.Note
This sample has Cortex-M Security Extensions (CMSE) enabled and separates the firmware between Non-Secure Processing Environment (NSPE) and Secure Processing Environment (SPE). Because of this, it automatically includes the Trusted Firmware-M (TF-M).
-
After building the sample successfully, the firmware with the name
merged.hex
can be found in thebuild
directory.
Flashing the firmware¶
Set up your board before flashing the firmware. You can flash the sample using west flash
:
Tip
In case you wonder, the west flash
will execute the following command:
Testing¶
After programming the sample, test it by performing the following steps:
-
Open up a serial terminal, specifying the correct serial port that your computer uses to communicate with the nRF9151 SiP:
- Start PuTTY.
-
Configure the correct serial port and click Open:
-
Press the DFU/RST button to reset the nRF9151 SiP.
-
Once the device is provisioned and connected, you should see the output, similar to what is shown in the following:
-
Press USR/P25 button to send an alert message to nRF Cloud.
-
Explore the device’s page to see more features of nRF Cloud, such as Device Information, Device Data, Terminal, Temperature and Device Alerts, etc.
