Working firmware for the Fanstel gateways, four ways to have it. Flash a signed image to judge it, or to deploy it as it is. License the source, module by module, to change and ship. Or build your own from scratch, with the agent already holding the board’s pinouts and radios.
A Bluetooth tagOr a sensor, a beacon, a wearable. Anything that advertises.
The gatewayHears it, filters it, and holds it when the link is down.
Ethernet, Wi-Fi or cellularIn the order you choose. It falls back on its own and comes back on its own.
Your brokerYour MQTT, your cloud, your rules. Nothing of ours in the path.

The same path whichever way you get the firmware. What changes is how much of it is yours to change.

No subscription. The demo is free to flash and judge. A production licence is bought once per relay, with a year of updates. Licensed source, or a build from scratch on the free tier, is the other way.

​
The four ways, per gateway

Each cell is the time to a first working version on the real board. Satellite NB-NTN ships in the relays’ firmware, on the BLG20x and the LBG20x. On-device inference on the nRF54 also ships as knowledge and a guided run. LoRa on the LEW840x, from the LR62XE radio on its M262X840XE card, is in preparation: the board knowledge is opened per account on request, the firmware line is not yet released. See LoRa and LoRaWAN.

Flash, to judge or to deploy

Register, free and with no card, then flash. Wi-Fi and Ethernet run without limit. Cellular runs in 60-minute sessions while you evaluate.From 0.5, a firmware version is downloaded from the Hardware page in Adsum IoT Coder into your workspace, under firmware/<family>/<version>/, or into a folder you choose. The licence file and a receipt land beside the files; the download is authorised freshly by the server at the moment you click, and every file is checked against its hash before it is kept. The agent flashes from that folder and says so on every flash (“Flashing BLG20x v2.3.0, licensed to your organisation, from firmware/blg20x/2.3.0/…”); it never reads an image into the conversation and never copies one outside the workspace. A version your account does not hold is a state on the page, never a wall: a demo opens with a free account, and a production version opens with a licence: per relay at www.adsumnetworks.com for the BLG20x and LBG20x, by request for the others (Ask to renew). Files already on disk stay yours to flash after a term ends.
Firmware versions: BLG20x demo pair v1.0.0, yours and on disk, licensed until 2027-10-09, with Flash and Open folder; BLG20x production v2.3.0, renew to have this, with Ask to renew

The Hardware page: the demo pair on disk, ready to flash, and a production version this account does not hold.

On a BLG20x or an LBG20x the same page also works over Bluetooth, from 0.5.1. It lists the units it hears under Gateways in range: Connect pairs (when the computer asks for a passkey, the page shows the six digits), Claim locks the unit’s service port to this computer’s key, and Check firmware compares what the unit runs with the latest demo release. A newer release is flashed over Bluetooth from the firmware rows, the Bluetooth half first, and the unit keeps its settings. The fourth step commissions the unit: see the first run, Step 3.

License the source, to ship

Ask from Settings › Account › Request template source, or write to support@adsumnetworks.com. You get the code, the board knowledge behind it, and the agent that moves it forward when the SDK does.

Build from scratch, or extend

Add a sensor, a rule, a bearer, or start from nothing. Every build can carry a CRA readiness check, reporting that build’s own evidence.

BLG20x and LBG20x

The BLG20x board, with the radio modules and the SIM holder

The board inside: the radio modules and the SIM holder.

The Adsum NTN Relay: industrial-grade firmware on the Fanstel BLG20x, indoors, and the LBG20x, outdoors with its own GNSS fix. Bluetooth LE devices in; LTE-M, NB-IoT and satellite NB-NTN out; Edge AI on board; signed updates over the air. Over satellite it sends the decision, not the data: alerts and status only, in one 128-byte datagram. A guided first run takes a relay from an unflashed board to readings on your own platform and a command sent back. The demo is on every relay from Fanstel; production licences are per relay at www.adsumnetworks.com, and source is quoted.

​
What a licence gives

For the BLG20x and LBG20x, a licence is per relay: our production firmware on one relay, for good, with security fixes for five years, a year of new versions (renewed a year at a time) and the evidence pack, bought at www.adsumnetworks.com. For the LEW840x and BWG840x, source licences are per module and per company: tell us what you are building and we agree terms. Your modifications stay yours, the source comes with the board knowledge the agent uses to extend it, and every build gets signed images, hash-verified before they flash.

​
Who does what, and where to buy

Fanstel designs, makes and sells the hardware. Adsum writes, verifies, signs and licenses the firmware and the knowledge. Buy the BLG20x, the LBG20x, the LEW840x, the BWG840x and their cards from Fanstel, who is taking the BLG20x through the hardware certifications for each region. Buy the nRF9151 DK and nRF54 boards from Nordic Semiconductor. Licensing a pack for your own integrators: support@adsumnetworks.com. The extension is Apache 2.0 and the bundled knowledge is CC-BY-SA. Gateway firmware is licensed separately, and the images are free to evaluate.
