Adsum Networks
Adsum Networks provides production-grade gateway firmware that connects Bluetooth IoT devices to satellite and cellular networks, running on Fanstel's open hardware relays. The firmware ships with a free demo image, and a VS Code-based AI coding agent helps developers customize device handling or build firmware from scratch. A catalogue of 442 Bluetooth devices from 35 makers is supported, with 183 device profiles already shipping in production firmware.

Problem
Embedded IoT firmware development is slow and error-prone, especially for complex systems involving Nordic nRF and Espressif ESP32 platforms. General-purpose AI coding agents lack the hardware-specific knowledge needed to produce working code, and achieving regulatory compliance like EU CRA readiness requires specialized expertise that most teams don't have in-house.
Solution
Adsum Networks provides production-grade gateway firmware that carries Bluetooth devices over satellite (NB-NTN) and cellular networks, running on Fanstel's open hardware BLG20x and LBG20x relays. The firmware is available in four forms: a free demo image pre-loaded on every relay, a signed production image licensed per relay, licensed source code for modification and shipping, or a from-scratch build guided by the Adsum IoT Coder AI agent. The agent reads the entire development bench—build outputs, flash outputs, and device responses—not just source code, and every file write and command waits for developer approval. The relay's firmware is split into two layers: one the customer owns and can change (device admission and data handling) and one signed by Adsum (uplinks, security, boot, and updates). A device catalogue lists 442 Bluetooth devices from 35 makers, with 183 device profiles already shipping in production firmware and 259 more available on request within one business day.
Target Audience
Embedded IoT developers and engineering teams building firmware for Nordic nRF and Espressif ESP32 platforms, particularly those working on wireless gateways and IoT devices requiring regulatory compliance. The NTN Relay is also targeted at organizations needing satellite connectivity for distributed Bluetooth sensor networks.
Features
- Hardware-verified expert knowledge for Nordic nRF and Espressif ESP32 platforms, including nRF54 edge AI and satellite NB-NTN capabilities
- Reads the whole development bench—log snippets, build outputs, flash outputs, and device responses—not just source code
- One-click EU CRA readiness for regulatory compliance
- Built-in catalogue of 183 device profiles covering 442 Bluetooth devices from 35 makers, with custom profile certification in hours
- Two-layer firmware architecture: customer-modifiable device admission layer and Adsum-signed uplink, security, boot, and update layer
- Privacy-first design: runtime runs locally, project memory in a plain `.adsum/` folder, no project data sent to Adsum
- Supports local models through Ollama or LM Studio for fully offline operation
- Enterprise features include cellular, satellite NB-NTN, nRF54 edge AI, and LEW840x gateway firmware knowledge with free account
