In this article, you will find details on various supported cellular networks and the particular settings in various environments. The CHESTER platform supports LTE-M and NB-IoT cellular technologies using nRF9160 System-in-Package from Nordic Semiconductor.

In HARDWARIO, we do not restrict customers to use any SIM card provider of their preference (as long as the selected carrier offers one of the supported cellular technologies). On the other hand, for the SIM cards provided by HARDWARIO, we can provide an extended level of technical support.

As of now, we can deliver SIM cards for these three carriers:

  • Vodafone in European countries.
  • 1NCE for other providers in non-European countries.
caution

We only support the Nano-SIM form factor (4FF) for plastic SIM cards. Alternatively, HARDWARIO can provide a SIM chip variant (MFF2) for bulk orders.

Network Settings

This article provides a settings reference for the tested networks and the current Cloud v2.

In case of older firmwares, see legacy Cloud v1 chapter.

caution

The table below applies to the SIM cards provided by HARDWARIO. We cannot guarantee data validity if the SIM cards are sourced from anywhere else.

Configuration Parameters​

antenna – Antenna Type​

Defines the type of antenna connected to the device:

  • internal – Use the built-in antenna.
  • external – Use an externally connected antenna.

mode – Network Mode Selection​

Specifies the preferred network connectivity modes and their priority:

  • lte-m,nb-iot – Prefer LTE-M, fallback to NB-IoT.
  • nb-iot,lte-m – Prefer NB-IoT, fallback to LTE-M.
  • lte-m – Use LTE-M only.
  • nb-iot – Use NB-IoT only.

⚠️ Ensure the selected mode is supported by your SIM card and the local network operator.

apn – Network APN (Access Point Name)​

Defines the APN required to connect to the mobile network:

  • The IP address is provided by the SIM card provider.
  • Leave empty for auto-configuration, if supported by the network and modem.

auth – Authentication Method​

Defines the method of APN authentication:

  • "none" – No authentication.
  • "pap" – Use PAP authentication (if supported).
  • "chap" – Use CHAP authentication (if supported).

If your SIM does not require authentication, use "none".

The password used for APN authentication.
Leave empty ("") if authentication is not required.

addr – Static IP Address​

Specifies the static IP address assigned to the LTE network interface. For global connection use "157.245.24.13"

Test commands​

You can verify the settings using this command:

lte config show

Run this command to query the LTE registration state:

lte state

You can read the IMSI of the SIM card even when the CHESTER is not attached:

Cloud v1 configuration​

For our legacy HARDWARIO Cloud v1 firmwares (usually CHESTER catalogue firmware version is 2.x.x) you need to use a different settings for these two config items:

  • IP with Vodafone SIM card: lte config addr 192.168.168.1
  • IP with non-Vodafone SIM card: lte config addr 165.227.146.193
  • APN: lte config apn hardwario.com

Notice the APN has a .com suffix, and IP leads to Cloud v1 UDP server.

Don't forget to save configuration changes by typing config save.

List Available Networks​

You can use CHESTER to scan for networks it can see. This is mainly for troubleshooting purposes. you have to use J-Link RTT connection with HARDWARIO CLI, this doesn't work with a BLE connection.

Open HARDWARIO CLI console by typing hardwario chester app console

lte config test true
config save

lte test uart enable
lte test wakeup
lte test cmd at\%xsystemmode=1,1,0,0
lte test cmd at+cfun=1
lte test cmd at\%cops=?

<wait for %COPS response>

lte config test false
config save
warning

Don't forget to disable modem test mode after you get the %COPS response so CHESTER can work properly again.

lte config test false
config save

Response will be in application log during several minutes (e.g. ~3 minutes with usual bandlock for Bands 2, 4, 5, 8, 12, 20, 28) in the form like:

%COPS: (2,"","","26201",7),(1,"","","26202",7)

Output explanation:

%COPS: [(<stat>,long alphanumeric <oper>,short alphanumeric <oper>,numeric <oper>[,<AcT>])]

<stat>

  • 0 – Unknown
  • 1 – Available
  • 2 – Current
  • 3 – Forbidden

<oper>

  • PLMNID of operator

<AcT>

  • 7 – LTE-M
  • 9 – NB-IoT
