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.
