Summary

Heltec Wireless Tracker is a development kit based on ESP32-S3FN8. It integrates both SX1262 and UC6580 to provide fast GNSS solution for IoT. It can track any object and then upload that data wirelessly by Wi-Fi, Bluetooth, and LoRa.

Wireless Tracker supports L1 + L5/L2, and supports GPS, GLONASS, BDS, Galileo, NAVIC, QZSS multi-system joint positioning. It is perfectly compatible with Arduino, can be widely used in development such as bicycle sharing services, tracking pets or livestock, locating vehicles, tracking children, etc.

Wireless Tracker supports the following development methods:

Wireless Tracker is compatible with the following open-source projects:

• ◆ ESP32 Paxcounter

• • ◆ Disaster Radio

• • ◆ Meshtastic (hot☆☆☆☆☆)

    • • • • ◆ Tiny GS

We also provide a standard ESP32 Arduino LoRaWAN library:

• Heltec ESP32 LoRaWAN

This library is already included in the Heltec ESP32 Arduino Framework by default.

Main Features

• ◆ ESP32-S3FN8+SX1262+UC6580 Chipset, supports Wi-Fi, LoRa, Bluetooth, GNSS.

• • ◆ Low power design of dual-frequency multi-system based on 22nm technology.

• • ◆ Supports L1 + L5/L2, supports GPS, GLONASS, BDS, Galileo, NAVIC, QZSS multi-system joint

     positioning.

FAQ

If you encounter an issue where your device is unable to download a program, you can

follow these steps to resolve it.

   1. Check if the USB cable supports data transfer by verifying if the connected cell phone supports file

        transfer.

   2. Connect the USB cable, press and hold the ‘USER’ key, then press the ‘RST’ key once. Finally,

        release the ‘USER’ key to initiate the code download.

Upon downloading the code, if the screen does not respond?

     Connect the serial port and check whether the node is activated. If the node is not activated, refer to

     this link to activate it: //docs.heltec.org/general/how_to_use_license.html.

GNSS data is displayed as ‘0,0,0’ ?

     1.Confirm your hardware version, V1.1 has changed the power control pin of the GNSS chip (GPIO 3

         is set to HIGH on). Please carefully review the schematic or refer to the corresponding hardware

        version’s example program.

     2.GNSS requires open outdoor environments or try with an external antenna.

How can LoRa be useful in your home automation projects?

     Imagine that you want to measure the moisture in your field. Although, it is not far from your house, it

     probably doesn’t have Wi-Fi coverage. So, you can build a sensor node with an ESP32 and a

     moisture sensor, that sends the moisture readings once or twice a day to another ESP32 using

     LoRa.The later ESP32 has access to Wi-Fi, and it can run a web server that displays the moisture

     readings.This is just an example that illustrates how you can use the LoRa technology in your ESP32

     projects.

Meshtastic firmware can’t operation the V1.1’s GNSS?

     This issue had been well solved in the last update. The firmware will automatically recognize the

     device version and operation it.
