What
This page is about investigation of Sigfox location trackers, e.g.:
- how existing trackers work
- coverage of the sigfox network
- how to interact with the sigfox backend
- ultimately, help develop a sigfox tracker for tracking small animals, like bats
Investigation
- great page at disk91 about sigfox, part from reverse engineering
- coverage map https://www.sigfox.com/en/coverage
- modulation is D-BPSK, frequency range is 192 kHz is in the 868 MHz band
- a packet consists of max 26 bytes, of which 12 bytes are user payload

This is a tracker made by Invoxia, features:
- sends positions using sigfox, configured via bluetooth
- fcc id ZVS-LWT1: https://fccid.io/ZVS-LWT1/Internal-Photos/Internal-Photos-3734578
- ESP-8285 chip, this is a microcontroller similar to ESP-8266, can do wifi but not bluetooth (AFAIK)
- NXP-QN9080, Ultra low power Bluetooth 5 system-on-chip solution, see https://www.nxp.com/docs/en/nxp/data-sheets/QN908x.pdf
- U-blox M8030-CT, GNSS chip,see https://www.u-blox.com/en/product/ubx-m8030-series
- Semtech SX1272, LoRa chip
- LiPo battery, 352044 300 mAh 3.7V
- chip antenna for LoRa/Sigfox
- chip antenna for wifi/bluetooth/gps
Apparently this was originally a LoRa tracker, contains a LoRa transceiver, but now uses SigFox!
