Extending Bitchat with Long-Range aiTalk Hardware

[niuzhongjin]

Hi @jackjackbits and the permissionlesstech team,

My name is Alan Niu from TaoLink, a wireless communications semiconductor company in China.

We share Bitchat's vision: everyone should be free to communicate without cellular networks, internet access, accounts, or centralized infrastructure.

Driven by the same belief, we developed aiTalk—a compact Sub-GHz communication device designed to give virtually any smartphone long-range offline communication capabilities through BLE.

aiTalk is not a concept or laboratory prototype. It is a mature, commercially available product supported by proprietary communication silicon, firmware, an Android SDK, reference designs, and mass-production support.

Its key capabilities include:

• Offline messaging, location sharing, PTT, and real-time full-duplex voice.
• Proprietary ultra-low-bitrate voice codecs supporting full-duplex voice at 2.4 kbps and 1.2 kbps, and low-latency PTT voice at 0.325 kbps.
• Kilometer-scale direct communication in real-world environments.
• Lightweight, low-cost relays providing an approximately 50-kilometer coverage radius per hop under suitable conditions.
• Multi-hop networks that can extend across hundreds or potentially thousands of kilometers, depending on terrain, relay deployment, and local radio regulations.
• Integration as either a smartphone companion device or a built-in capability for Android phones and professional terminals.

We already have products available for purchase and evaluation, and the technology has been validated through mobile phone OEM projects.

We are willing to develop the SDK, firmware, and transport adapter required to connect aiTalk with Bitchat:

Bitchat ↔ BLE adapter ↔ aiTalk ↔ Sub-GHz network

Existing aiTalk devices could support Bitchat through a software or firmware upgrade, without requiring new hardware development.

We believe this could expand Bitchat from nearby BLE messaging into a wide-area platform supporting messaging, PTT, and real-time voice across hundreds or even thousands of kilometers.

We already have the physical device. The remaining step is to connect the software and turn our shared vision into reality.

Would you be open to a brief technical discussion?

Best regards,
Alan Niu

What about iOS ?

[niuzhongjin]

Yes. aiTalk fully supports both iOS and Android. Our app is already available on both platforms, and our iOS and Android SDKs are mature and production-ready. The hardware, app, and SDK are all ready, and we can support Bitchat integration on both platforms.

Hola@jackjackbitsy el equipo de permissionlesstech,

Mi nombre es Alan Niu, de TaoLink, una empresa china de semiconductores para comunicaciones inalámbricas.

Compartimos la visión de Bitchat: que todo el mundo sea libre de comunicarse sin redes celulares, acceso a internet, cuentas ni infraestructura centralizada.

Impulsados ​​por esa misma convicción, desarrollamos aiTalk , un dispositivo de comunicación compacto de sub-GHz diseñado para brindar a prácticamente cualquier teléfono inteligente capacidades de comunicación sin conexión de largo alcance a través de BLE.

aiTalk no es un concepto ni un prototipo de laboratorio. Es un producto maduro y disponible comercialmente, respaldado por un chip de comunicación propietario, firmware, un SDK de Android, diseños de referencia y soporte para la producción en masa.

Sus principales capacidades incluyen:

• Mensajería sin conexión, uso compartido de la ubicación, pulsar para hablar y voz dúplex completo en tiempo real.
• Códecs de voz propietarios de tasa de bits ultrabaja que admiten voz dúplex completo a 2,4 kbps y 1,2 kbps , y voz PTT de baja latencia a 0,325 kbps .
• Comunicación directa a escala kilométrica en entornos del mundo real.
• Repetidores ligeros y de bajo coste que proporcionan un radio de cobertura de aproximadamente 50 kilómetros por salto en condiciones adecuadas.
• Redes de múltiples saltos que pueden extenderse a lo largo de cientos o incluso miles de kilómetros , dependiendo del terreno, el despliegue de repetidores y las regulaciones de radio locales.
• Integración como dispositivo complementario para smartphones o como función integrada en teléfonos Android y terminales profesionales.

Ya disponemos de productos para su compra y evaluación, y la tecnología ha sido validada a través de proyectos de fabricantes de equipos originales (OEM) de telefonía móvil.

Estamos dispuestos a desarrollar el SDK, el firmware y el adaptador de transporte necesarios para conectar aiTalk con Bitchat:

Bitchat ↔ BLE adapter ↔ aiTalk ↔ Sub-GHz network

Los dispositivos aiTalk existentes podrían ser compatibles con Bitchat mediante una actualización de software o firmware, sin necesidad de desarrollar nuevo hardware.

Creemos que esto podría expandir Bitchat, pasando de la mensajería BLE cercana a una plataforma de área amplia que admita mensajería, PTT y voz en tiempo real a lo largo de cientos o incluso miles de kilómetros.

Ya contamos con el dispositivo físico. El paso que falta es conectar el software y convertir nuestra visión compartida en realidad.

¿Estaría dispuesto a tener una breve conversación técnica?

Saludos cordiales, **Alan Niu ** **TaoLink / aiTalk ** [email protected]

Hello, my name is Rodrigo and I would like to know more about your Bluetooth mesh P2P messaging protocol. I currently need to open a gateway to an app on mobile devices and I think we could make an excellent match. If you'd like, send me an email and we can talk ([email protected]). Thank you.
