¶ Nordic cellular module
This guide will walk you through connecting a Nordic Semiconductor device to the IoT Bridge. Once connected, you can leverage any of our upstream connectors for rapid integration into your application.
¶ Pre-requisites
- Account on Tartabit IoT Bridge.
- Nordic nRF-9160 development kit or a Thingy91 device.
- nRF Connect for Desktop v3.11.0+
- Visual Studio Code
¶ 1. Configure your module image
- Open VS Code with nRF Connect.
- Navigate to the
Welcome to nRF Connecttab in VS Code. - Click
Create a new application from sample.... - Configure your new application...
a. Application type:Freestanding
b. nRF Connect SDK:1.9.1or newer
c. nRF Connect Toolchain:1.9.1or newer
d. Application location: wherever you want.
e. Application template:nrf/samples/9160/lwm2m_client.
f. Application name:tartabit_client.
g. ClickCreate Application. - Create a new file in your project called
overlay-tartabit.confwith the following contents.
CONFIG_APP_LWM2M_SERVER="lwm2m-us.az.tartabit.com"
CONFIG_APP_LWM2M_PSK="11223344556677889900"
CONFIG_LWM2M_ENGINE_DEFAULT_LIFETIME=120
-
Switch to the
nRF Connecttab in VS Code. -
Under
Applicationsfindtartabit_clientand click theAdd build configurationicon.
a. Set board tonrf9160dk_nrf9160_nsorthingy91_nrf9160_nsdepending on your device type.
b. Set Kconfig fragments tooverlay-tartabit.conf.
c. ClickBuild Configuration. -
Connect your device to your PC and ensure the serial ports are visible.
-
Click
Flash all linked devices.
¶ 2. Configure IoT Bridge
- Login to the
Tartabit IoT Bridge. - Navigate to
Solution Templatesat the bottom of the screen. - Find the Nordic template for either the
NRF9160DKorThingy91and clickImport. - Enter the IMEI of your device and update the PSK to whatever value you placed in the
tartabit-overlay.conffile. - Select a previously created instance of the LWM2M Service.
- Click
Import.
¶ 3. Connect your device
- Reset the device either by pressing the reset button or through the console.
- Use the terminal in VS Code or
LTE Link Monitor, the output should look like this:
[00:00:01.849,365] [0m<inf> app_lwm2m_client: Connecting to LTE network.
[00:00:01.849,395] [0m<inf> app_lwm2m_client: This may take several minutes.
[00:00:06.899,536] [0m<inf> app_lwm2m_client: Connected to LTE network
[00:00:06.900,848] [0m<inf> net_lwm2m_rd_client: Start LWM2M Client: urn:imei:352656100393787
[00:00:07.509,033] [0m<inf> net_lwm2m_rd_client: RD Client started with endpoint 'urn:imei:352656100393787' with client lifetime 0
[00:00:23.426,544] [0m<dbg> app_lwm2m_client.rd_client_event: Registration complete
[00:00:23.426,666] [0m<inf> app_lwm2m_client: Obtained date-time from modem
[00:00:23.435,729] [0m<dbg> gps_module.start_gps_search: Started GPS scan
[00:00:23.435,760] [0m<inf> net_lwm2m_rd_client: Registration Done (EP='6qezdyuDjA')
- Check the
Endpointssection of the IoT Bridge and verify your device connected.
¶ If your SIM requires an APN to be specified
- Add the following to your
tartabit-overlay.conffile:
CONFIG_PDN=y
CONFIG_PDN_SYS_INIT=y
CONFIG_PDN_DEFAULTS_OVERRIDE=y
CONFIG_PDN_LOG_LEVEL_DBG=y
CONFIG_PDN_DEFAULT_APN="my.apn"
CONFIG_PDN_DEFAULT_FAM_IPV4=y
Update the required values depending on your operator.
