# Bitle Adds LoRa to Bitchat's Solar-Powered Mesh Network, Enabling Multi-Kilometer Hops and State-Spanning Communications **Source:** https://glitchwire.com/news/bitle-adds-lora-to-bitchats-solar-powered-mesh-network-enabling-multi-kilometer/ **Published:** 2026-07-17T14:57:39.177Z **Author:** Tech Desk ยท Glitchwire **Categories:** Tech, Crypto ## Summary The open-source ESP32 relay node project just gained long-range radio capability, transforming local Bluetooth mesh pockets into potentially continental-scale infrastructure for encrypted messaging. ## Article [Bitle](https://bitle.org/), the open-source solar-powered mesh relay node for Jack Dorsey's Bitchat messaging app, has added LoRa capability to its ESP32-based hardware. The update transforms what was previously a Bluetooth-only relay network into a hybrid system capable of 2 to 10 kilometer hops depending on terrain, while preserving the end-to-end encryption that defines the Bitchat protocol. The implications are significant. Bluetooth mesh networks are useful but range-constrained; even with multiple relay nodes, practical coverage maxes out at a few hundred feet per hop. LoRa changes the calculus entirely. In rural conditions, a single hop can span 10 kilometers. Urban environments typically see 1 to 3 kilometers. String enough solar-powered Bitle nodes together and you have the foundation for something that could, in theory, blanket entire states. ![Bitle ESP32-S3 & ESP32-C3 relay nodes form a short and long range ambient mesh network.](https://cdn.glitchwire.com/HNbyLOFWUAAmEdZ.jpg) *Bitle ESP32-S3 & ESP32-C3 relay nodes form a short and long range ambient mesh network.* ## The Ambient Mesh Concept The idea of an ambient mesh network has been circulating in decentralized communications circles for years, but the hardware requirements always made it impractical for civilian deployment. You needed too many nodes, too much power, too much maintenance. Bitle's approach sidesteps those problems. The device runs on an ESP32-C3 microcontroller with solar charging and battery backup. According to the project's specifications, nodes can run indefinitely on solar power or approximately 25 to 50 days on battery alone. The firmware is fully autonomous. Flash it, deploy it, and walk away. No user interaction required. This is the key insight: infrastructure that doesn't need human attention can scale in ways that attended systems cannot. Hikers could install nodes along trails. Farmers could mount them on fence posts. Anyone with a rooftop and sunlight could contribute to the network without ongoing commitment. ## How It Works Bitchat itself is a peer-to-peer encrypted messaging app announced by Dorsey in July 2025. It uses Bluetooth Low Energy mesh networking, the Noise Protocol Framework for encryption, and optionally routes through Nostr relays when internet connectivity is available. The app supports multi-hop message relay through nearby devices, meaning your phone can reach someone else's phone even if they're not in direct Bluetooth range. Bitle extends this by acting as a dedicated relay node. It runs a NimBLE GATT service, handles Noise XX handshakes, validates packets, and re-broadcasts encrypted payloads without user interaction. The LoRa addition connects these Bluetooth mesh pockets to longer-range radio infrastructure, bridging isolated user groups that would otherwise be unable to communicate. The [Bitle GitHub repository](https://github.com/bitleproject/bitle) includes the complete firmware source code under MIT license. Anyone can clone it, flash a board, and deploy. ## Payments Over Mesh Bitchat already supports Cashu ecash transfers via the /pay command. Cashu is a Chaumian ecash protocol built on Bitcoin that allows peer-to-peer token transfers without involving the mint or any server. The tokens are bearer instruments, just text strings that can be sent over any communication channel. This matters because it means financial transactions can traverse the same mesh infrastructure as messages. In regions with unreliable internet or during crises, the ability to send encrypted payments across kilometers of dead zone changes what's possible. [The race to own the financial layer](/news/x-money-and-google-finance-converge-on-the-same-thesis-own-the-financial-layer/) is usually fought over internet-connected systems. Bitle points toward something different. ## Why Open Source Matters Here A network that operates without central coordination requires radical transparency. If users are going to deploy nodes on their property, potentially handling sensitive communications, they need to be able to audit exactly what those nodes are doing. The MIT license means anyone can fork, modify, contribute, or build commercial products on top of the codebase. Hardware designs could proliferate. Regional mesh cooperatives could form without negotiating licenses. This is the model that made [Meshtastic](https://en.wikipedia.org/wiki/Meshtastic) successful, and Bitle appears to be following a similar path. Bitchat saw significant adoption during internet blackouts in Uganda, Iran, and Madagascar. It was used by protesters in Nepal. China requested its removal from the App Store in April 2026. The pattern is clear: demand for [infrastructure-independent communication](/news/europes-looming-social-media-ban-for-under-13s-a-policy-caught-between-good-intentions-and-uncertain-outcomes/) spikes precisely when such infrastructure is needed most. Whether Bitle can deliver on the promise of state-spanning ambient mesh remains to be seen. The physics work. The economics are favorable. What's missing is deployment density, and that's a problem only solved by people actually installing nodes. --- **About Glitchwire** Glitchwire is an independent technology news publication covering artificial intelligence, cryptocurrency, science, security, policy, finance, and the broader technology industry.
