SX1302 gateway — Waveshare HAT captures and Lora-net sx1302_hal (inbox batch 2026-04-20)

Purpose: Provenance for Semtech SX1302/SX1303 gateway software (upstream HAL / packet forwarder) plus Waveshare Pi HAT vendor captures (EU868 module + GNSS). Not RF regulatory or site-survey advice—follow local band rules and licensed professionals where applicable.

Downstream hubs: Smart agriculture, Meshtastic, and LoRaWAN · LoRa, MQTT, and gateway bridges · Demory farm sensor layer — official and operator-grade source cluster

Evidence summary

Field Content
Abstract Three markdown captures: (1) Lora-net sx1302_hal project readme—libloragw, packet forwarder, USB vs SPI, build/changelog; (2) Waveshare wiki—HAT setup with The Things Stack, Pi 4/5 demos, FAQs; (3) Waveshare product page—discontinued-SKU notice, kit list, L76x GNSS. Together they support gateway bring-up literacy next to LoRaWAN stack docs already in the vault.
Authority mix Upstream open-source (Semtech/Lora-net) + vendor (Waveshare wiki/product)—hardware facts and procedure color; corroborate regulatory band use with primary radio rules.
Decision relevance Choosing SX1302-class Pi gateways, sx1302_hal / packet forwarder paths, TTS registration, GNSS-assisted gateway time; EU868 vs other regional products.
Canonical wiki links LoRaWAN · Inbox batch — Tennessee farm policy, LoRaWAN field stack, ChirpStack, Meshtastic, Decentlab, HaLow (2026-04-18)

Key claims (public-safe; cite raw for version-specific detail):

  • sx1302_hal documents SPI and USB Corecell paths, packet_forwarder uplink/downlink over UDP, reset_lgw.sh co-location with binaries, and cross-compile / target.cfg install flows.
  • Waveshare HAT docs describe EU868 focus, L76K/L76B GNSS for PPS/time, Mini-PCIe SX1302 module, and TTS-oriented EUI / test_conf.json steps.

Open questions / follow-ups

  • If a live two-site deployment standardizes this HAT, fold hardware-specific runbook rows into an operational guide and standards page—this note stays vendor + upstream provenance.

Raw sources and ingest descriptions

Ingest description Raw
Lora-net sx1302_hal readme (tools, packet forwarder, changelog). Semtech/Lora-net documentation for the SX1302/SX1303 gateway HAL: libloragw builds to a static library; packet forwarder bridges concentrator RF to UDP for a network server; helpers include util_chip_id (gateway EUI), util_net_downlink, util_boot (USB DFU for STM32 bridge), util_spectral_scan (sx1261 on Corecell v3). Covers SPI vs USB (USB uses STM32 USB↔SPI bridge; MCU firmware in mcu_bin), tools/reset_lgw.sh GPIO init, make / target.cfg install and ARM cross-compile, third-party libs (parson, tinymt32), and a long changelog (fine timestamping, spectral scan, LBT AS923, SX1303, PROTOCOL updates, CN490 full-duplex merges, etc.). Ends with Semtech legal disclaimer. lora-net-sx1302-hal-readme-packet-forwarder-tools.md
