Configuration

Before you begin

You will need: a nano-format SIM card with the PIN code disabled (see instructions for iOS or Android).

Accessing the command prompt

You can access the command prompt to communicate with a GEOSTIX in two ways:

• wirelessly via Bluetooth using the GEOSTIX mobile app (Android or iOS)
• via USB wired connection (through a virtual COM port, see USB communication).

APN Configuration

Each layer equipped with 4G connectivity requires individual APN (Access Point Name) settings.

1. Insert the SIM card.

   Insert the SIM from the bottom of the 4G layer. The reader uses a push-pull mechanism: push the SIM card in fully (you’ll hear a click) and release. The SIM is inserted. To remove it, push it fully in again (you’ll hear a click) and release quickly.

2. Connect the GEOSTIX to the 4G layer

   Place the GEOSTIX on the 4G/LTE layer, aligning the notches, then screw the stainless ring onto the layer.

   Power on the system.

   You should see this:

   

3. Enter the connection parameters

   Wait for the 4G layer’s light to switch from orange to green (5 to 10 seconds).

   Send the letter “C” to the GEOSTIX via the command prompt. You’ll receive the following output with available 4G/LTE-related commands:

   cmd C

   >C
   'C' subcommands:
     C init IAMSURE : initialize modem
     C version : print module version
     C IMEI : print module unique identifier
     C unlock pin : enter pin to unlock SIM
     C AT command : send AT command
     C apn [value] : get/set gateway name
     C signal : report signal quality
   +OK
   >

   Typing just the first letters of a command runs it. For example, Cv will run “C version : print module version”.

   To configure the APN for your SIM card’s carrier, send Ca followed by the APN string.

   If your provider is Bouygues, send: Ca mmsbouygtel.com.

   Below is a list of carriers and their APNs:

   CARRIER	APN	CARRIER	APN
   Bouygues tel	mmsbouygtel.com	Carrefour Mobile	orange.acte
   Free Mobile	free	La Poste Mobile	wapdebitel
   M6 Mobile	ofnew.fr	NRJ Mobile	ofnew.fr
   NRJ Mobile	orange.acte	Orange & Sosh	orange
   PRIXTEL	sl2sfr	Virgin Mobile	ofnew.fr
   SFR	sl2sfr	SFR Blocked Plans	wapsfr

   The OK response may take several seconds to appear.

It is then advisable to perform a ping to ensure a proper internet connection:

cmd Np

>N
'N' subcommands:
  N info [interface]
  N ping host [timeout]
+OK
>Np 8.8.8.8
PING 8.8.8.8 (8.8.8.8): 32 data bytes
Request 0 time=186 ms
Request 1 time=26 ms
Request 2 time=38 ms
+OK

In the example above, the Np command pings the address 8.8.8.8, and the immediate responses confirm that the connection is working properly.
