Product details

Overview

IOT922STK1-8 from Semtech is a LoRaWAN gateway development kit built around a Raspberry Pi B+ and an SX1301-based concentrator reference design, preloaded with LoRaWAN server v1.4.2 and packet forwarder software, supporting 922 MHz regional band operation for APAC LoRaWAN deployments.

For engineers reviewing the IOT922STK1-8 datasheet, pinout, applications, or equivalent options, this kit enables rapid validation of end-node connectivity to public LoRaWAN networks, local gateway stack testing, GPS-synchronized time-stamping, and full-stack protocol conformance verification against LoRaWAN R3.0 specification.

Technical Context

The IOT922STK1-8 implements a complete Class A/C LoRaWAN gateway stack on Raspberry Pi B+, integrating Semtech's SX1301 baseband processor with dual SX1257 front-end transceivers for 922–928 MHz operation, and supports GPS timing synchronization for precise uplink timestamping and frequency calibration.

It runs a preconfigured Linux-based LoRaWAN network server (v1.4.2), MySQL database backend, web UI, and packet_forwarder daemon - all hosted on a pre-flashed microSD card - with LCD status indicators for gateway (G), server (S), and disk usage (D).

FAQ

What is the operating frequency band supported by the IOT922STK1-8?

The IOT922STK1-8 is configured for the 922–928 MHz ISM band, aligning with LoRaWAN Region 2 (APAC) regulatory requirements. This band assignment is fixed in the SX1301 firmware and packet_forwarder configuration files, and cannot be reconfigured to other regions like EU868 or US915 without modifying source code and recompiling the gateway stack.

Does the IOT922STK1-8 include a preloaded LoRaWAN network server?

Yes, the IOT922STK1-8 ships with Semtech's reference LoRaWAN network server v1.4.2 pre-installed on the microSD card. It runs as a daemon under /etc/init.d/lr-nwk-srv, connects to a local MySQL database, and serves a web UI accessible via the Raspberry Pi's assigned IP address - enabling immediate out-of-box evaluation of gateway-to-server data flow.

Can the IOT922STK1-8 operate without an Ethernet connection to a router?

Yes, the IOT922STK1-8 supports direct PC-to-Raspberry Pi Ethernet connection using a standard (not crossover) cable and static IP configuration (e.g., PC set to 192.168.1.2, IOT922STK1-8 defaults to 192.168.1.100). The LCD display shows both DHCP and static IPs, and the web UI remains fully functional in this isolated mode for local stack validation.

What GPS functionality does the IOT922STK1-8 provide?

The IOT922STK1-8 accepts input from an active GPS antenna to derive precise UTC timestamps for uplink packets and perform real-time frequency calibration of the SX1257 transceivers. GPS-derived timing is used by the packet_forwarder to synchronize gateways in multi-gateway deployments and improve geolocation accuracy.

Is the IOT922STK1-8 compatible with LoRaWAN end-devices using OTAA activation?

No - the preloaded LoRaWAN server in IOT922STK1-8 is hardcoded to support only ABP (Activation by Personalization) with fixed NwkSKey and AppSKey values. End-devices must be provisioned with those specific 16-byte keys ({0x11,…,0x00}) to communicate successfully; OTAA join-request processing is not implemented in this v1.4.2 server release.
