Quick Start - Zero IoT

This guide allows you to get the Zero IoT up and running in less than 5 minutes.

Prerequisites

Before starting, verify that you have:

  • ✅ Active SIM card with data (nano SIM)
  • ✅ Carrier APN data
  • ✅ Tracking server IP and port
  • ✅ USB Micro-AB cable or 9-90VDC power source
  • ✅ Serial terminal software or Web Serial

Step 1: Insert SIM Card

Important: Insert the SIM with the device unpowered.

  1. Remove the device cover
  2. Insert the nano SIM into the slot
  3. Replace the cover

Step 2: Power the device

Connect the Zero IoT via:

  • USB: Micro-AB cable to PC/Charger
  • Vehicle power: 9 to 90 VDC

The LED will start blinking indicating the device is powering on.

Step 3: Connect to the device

  1. Open Web Serial in Chrome/Edge
  2. Connect USB to the device
  3. Select the COM port

Option B: Serial terminal

  1. Open terminal software (PuTTY, Termite, etc.)
  2. Configure: 115200 bps, 8N1
  3. Connect to the device’s COM port

Step 4: Configure APN

Send the CXAPN command with carrier data:

>SCXAPNhost,usuario,password<

Examples by country:

CountryCarrierCommand
ArgentinaClaro>SCXAPNinternet.ctimovil.com.ar,<
ArgentinaMovistar>SCXAPNinternet.gprs.unifon.com.ar,wap,wap<
ArgentinaPersonal>SCXAPNgprs.personal.com,<
MexicoTelcel>SCXAPNinternet.itelcel.com,<
ChileEntel>SCXAPNimovil.entelpcs.cl,entelpcs,entelpcs<

If the carrier doesn’t require username/password, leave fields empty: >SCXAPNapn.name,<

Step 5: Configure server

Configure the tracking platform IP and port with the IP command:

>SIP0xxx.xxx.xxx.xxx/puerto<

Example with IP:

>SIP0190.168.1.100/5000<

Example with DNS domain:

>SIP0"tracking.mycompany.com",5000<

Zero IoT supports DNS resolution. For domains, use quotes and comma before port.

Step 6: Verify connection

Check cellular status

>QCEL<

Expected response:

RCEL,CONNECT,CAT-M,722,310
  • CONNECT = Connected to LPWA network
  • CAT-M or CAT-NB = Connection technology

Check device ID

>QID<

Expected response:

RID1234

Where 1234 is the device’s configured ID.

Step 7: Generate first report

To send an immediate position report to the server, use the G command:

>GGP00M<

This generates a GP type report (general position) with Medium priority.

Response:

GOK

Final verification

Common issues

Won’t connect to GPRS

  1. Verify SIM has active data plan
  2. Check APN with >QCXAPN<
  3. Wait 1-2 minutes for network registration
  4. Query >QCEL< to see connection status

Won’t report to server

  1. Verify IP with >QIP0<
  2. Generate manual report: >GGP00M<
  3. Verify server is listening on configured port

Won’t respond to commands

  1. Verify baudrate: 115200 bps
  2. Verify format: commands start with > and end with <
  3. Check USB connection

Next step

Once the device reports to the server, you can configure:
