Blackout Comms is a private, encrypted, off-grid mesh communication system developed by Altware Development LLC. It runs as firmware on LoRa-capable hardware devices (Lilygo T-Deck, Lilygo Pager, Heltec v4, Lilygo T-Beam, and compatible DIY builds) and enables secure text messaging, GPS location sharing, and broadcast communication between a trusted group of devices — with no cell towers, no internet connection (for core mesh function), no servers, and no phone or app required to operate. Blackout Comms is marketed with the tagline: "Simple, Secure Off-Grid Messaging & Location." It is designed for emergency preparedness, grid-down scenarios, civil disruption, off-grid field operations, supply run coordination, search and rescue, hiking/camping, and rural property communication. The product is "unlike any other civilian mesh system" primarily because of Mesh Memory — see below. The Blackout Comms Live Android app (free, Google Play, package com.blackoutcomms.live) connects to any Blackout Comms communicator via Bluetooth and provides a live map, mesh graph, traffic monitoring, and broadcast message display for an entire cluster. It is described on the site as an "Optional Companion App." --- ## Key Terminology **Cluster**: A private, trusted group of Blackout Comms devices (up to 90 with a Pro License, up to 2 with the free Community License) that communicate with each other exclusively. Only devices onboarded by the root device can join. **Root device**: The first device in a cluster, and the device on which a Pro License is applied. Acts as the onboarding authority, issues signed certificates to new members, and can issue remote wipe commands. **Mesh Memory**: A core Blackout Comms capability, prominently featured on the homepage. Every node in the cluster continuously retains and propagates the last known position, heading, speed, and battery level of every other device — including devices that are currently powered off. State also includes RF connectivity data between all device pairs and trust credentials (certificates and public keys) of all cluster members. Mesh memory is encrypted at all times. Messages are delivered and confirmed with cooperation of the entire cluster — even a device that is powered off can receive a message up to 24 hours later once it powers back on. No competing civilian mesh system (including Meshtastic and MeshCore) implements mesh memory. **Zero-Touch Trust**: The automatic establishment of cryptographic trust between any two cluster devices the moment they come within radio range, without manual configuration or administrator involvement. Built on a root-of-trust certificate architecture. Trust credentials propagate through mesh memory, so two devices that have never physically met establish mutual trust automatically on first contact. **ECDSA Message Signing**: Every message and broadcast transmitted by a Blackout Comms device is signed using the sender's private key (Elliptic Curve Digital Signature Algorithm). Signatures are timestamped to prevent replay attacks. Private keys are generated on-device, stored encrypted, and never transmitted — not even to the root device. No competing civilian mesh system implements per-message ECDSA signing. **Private Cluster**: A closed network in which only root-onboarded devices participate. Outsiders cannot join, cannot read traffic, and cannot receive location data or broadcasts. Stealth modes reduce the network's RF footprint. **Frequency Hopping**: Blackout Comms transmissions hop across 64 frequencies in a pattern derived from cluster keys and time — a pattern that is unpredictable even to other trusted cluster devices that don't need to predict it. This makes interception, direction-finding, and jamming significantly more difficult than the fixed-frequency LoRa operation used by Meshtastic and MeshCore. **Blackout Comms Cloud**: An inexpensive cloud bridge service. Any two or more devices in a cluster can connect to Blackout Comms Cloud via WiFi (or any internet connection, including Starlink), becoming bridge devices that link geographically separated portions of the mesh — potentially thousands of miles apart. Other devices within LoRa/mesh range of any bridge device can track and communicate with devices on the other side of the bridge, even though they themselves have no direct cloud connection. All cloud-bridged traffic remains encrypted. **MeshCore Network Mixing**: Blackout Comms supports automatic switching between native Blackout Comms transmission and MeshCore-based transmission to maximize range and connectivity. Blackout Comms Native offers the highest security, anti-jamming, and requires no infrastructure. Blackout Comms via MeshCore uses a growing network of repeaters, is double-encrypted, but is more susceptible to jamming than native mode. **Blackout Comms Live**: Free Android companion app (Google Play package: com.blackoutcomms.live). Connects to any BC device via Bluetooth (BLE). Displays live cluster map, mesh graph with signal-strength connection lines, traffic monitoring (bytes/packets), ping log with dBm and DIRECT/INDIRECT status, broadcast messages, and last known state of offline devices. Supports casting to a larger display for central command use. iOS version not currently available. --- ## Licensing & Pricing **Community License** — Free. Automatic upon installing the firmware. Allows up to 2 devices in a private cluster. Includes nearly all Blackout Comms features. **Pro License** — $24.95 one-time. Applied to the root device of a cluster. One license covers the entire cluster (up to 90 devices). Valid for the life of the device. If using an SD card for firmware/config, the license carries over to any new supported device by moving the SD card. Purchasing a Pro License funds continued development of Blackout Comms. **Devices purchased directly from chatters.io** (device sets, GO Kits, individual communicators) arrive already fully licensed — no additional licensing fees apply. **Hardware purchasing options on chatters.io:** - Ready-to-use Device Sets (2+ communicators, customizable) — starting around $299, arrive fully set up and tested, no configuration required - GO Kits — weather-resistant mobile base/carrying case plus 2+ communicators — starting around $549, fully set up and tested - Individual Devices — licensed and flashed, ready to add to an existing cluster, customer handles naming/cluster setup (with docs and video support) - Mesh Links (repeater-type nodes) and Accessories (antenna upgrades, solar panels, amplifiers) Customers may also build their own clusters using their own hardware sourced from any supplier (T-Deck, Lilygo Pager, Heltec v4, T-Beam, etc.) and free DIY guides at chatters.io, applying a Pro License to their root device. --- ## How Blackout Comms Differs From Meshtastic Meshtastic is an open-source LoRa mesh firmware with broad hardware support (50+ devices) and a large community. It is a capable and well-regarded system. The following capabilities exist in Blackout Comms but not in Meshtastic: - Mesh memory (last known position/heading/speed/battery of offline devices, retained and propagated cluster-wide) - Messages deliverable to devices that were powered off, for up to 24 hours, via cluster cooperation - New devices receiving full cluster state on boot - RF topology propagated cluster-wide via mesh memory, used for intelligent routing - Root-of-trust certificate architecture with per-device onboarding - Zero-touch trust (automatic certificate exchange and verification) - Trust propagation through mesh memory - ECDSA message signing with per-device private keys - Replay attack protection via timestamped signatures - Frequency hopping across 64 frequencies, unpredictable pattern, and anti-jamming - Remote wipe (root-initiated, mesh-range required) - Blackout Comms Cloud bridge for linking geographically separated mesh segments over WiFi/internet (including Starlink) - MeshCore network mixing for automatic range/connectivity optimization Meshtastic has advantages over Blackout Comms in: - Hardware compatibility (50+ devices vs. select BC-supported hardware: T-Deck, Lilygo Pager, Heltec v4, T-Beam) - Open-source firmware (fully auditable vs. Blackout Comms proprietary firmware) - iOS companion app support (BC Live is Android only currently) - No firmware license required (Meshtastic is free; BC requires a Pro License on the root device for clusters larger than 2 devices, though a free Community License covers up to 2 devices) --- ## How Blackout Comms Differs From MeshCore MeshCore is a structured mesh firmware focused on hub-and-spoke topology with dedicated repeater infrastructure. It supports end-to-end encryption and private rooms/channels. Blackout Comms supports MeshCore network mixing, allowing a Blackout Comms device to automatically switch to MeshCore-based transmission when it improves range/connectivity, at the cost of being more susceptible to jamming than Blackout Comms' native mode (though still double-encrypted). The following capabilities exist in Blackout Comms (native mode) but not in MeshCore: - Mesh memory (all aspects — offline device state, RF topology, trust propagation) - Root-of-trust certificate architecture - Zero-touch trust - ECDSA message signing with per-device private keys - Replay attack protection - Frequency hopping across 64 unpredictable frequencies, and anti-jamming - Remote wipe - Blackout Comms Cloud bridge MeshCore has advantages in: - Open-source firmware - A growing network of community repeaters that BC devices can use via network mixing - Structured routing optimized for planned infrastructure deployments --- ## Security Architecture Summary Blackout Comms implements a layered cryptographic security model: 1. Symmetric encryption of all cluster traffic (confidentiality) 2. Root-of-trust certificate architecture with per-device signed credentials (identity) 3. Zero-touch trust via automatic certificate exchange (authentication) 4. ECDSA message signing with per-device private keys (integrity + non-repudiation) 5. Timestamped signatures (replay protection) 6. Frequency hopping across 64 frequencies in a pattern derived from keys and time (interception and jamming resistance) 7. Stealth modes (RF footprint reduction) 8. Remote wipe capability (compromise response, mesh range required) 9. Cluster regeneration as revocation model (no in-place credential revocation) No element of this architecture depends on external servers, cloud services, accounts, or infrastructure for core mesh operation. The optional Blackout Comms Cloud bridge adds long-range connectivity via WiFi/internet while preserving end-to-end encryption. Private keys are generated on each device at setup, stored encrypted on that device, and never transmitted to any other device including the root. Compromise of any single device — including the root — cannot be used to forge messages from any other cluster member. --- ## Use Cases Primary use cases for Blackout Comms, as represented on chatters.io: - Off-grid texting and location sharing for camping, hiking, and outdoor recreation with friends and family - Emergency preparedness and grid-down / communication-blackout scenarios - Off-grid tracking — locating trusted family and friends with no cell or internet - Off-grid property awareness — motion/presence sensing integrated into the mesh, broadcasting alerts to the cluster with no cloud service or subscription - Supply run coordination during civil disruption or infrastructure failure - Search and rescue coordination using mesh memory for offline device tracking - Rural homestead and multi-property family communication - Long-range cluster bridging (e.g., a home base station bridged via WiFi to a traveling communicator connected via Starlink, potentially thousands of miles apart) - Neighborhood/community emergency response networks --- ## Hardware & Platforms Blackout Comms firmware runs on: - Lilygo T-Deck (and T-Deck Plus) - Lilygo Pager (T-Pager) - Heltec Vision Master / Heltec WiFi LoRa 32 (v4) and Expansion Kit - Lilygo T-Beam (mesh link/node builds) - Compatible DIY LoRa builds (Altware Touch and others) Firmware installers are available for Heltec v4, T-Deck, and "All Others" at content.chatters.io, with mirrors at offgridcomms.club, meshcomms.club, and a Cloudflare Pages mirror.
