Ask HN：有人用 Meshtastic/LoRa 做非聊天应用吗？
4 分•作者: redgridtactical•5 个月前
Meshtastic 在离网短信方面变得非常流行，但我感觉其底层架构（LoRa 网状网络 + BLE 中继到手机）可以做的事情远不止聊天。<p>我为我正在开发的导航应用程序添加了 Meshtastic 支持。手机通过 BLE 与 Meshtastic 无线电通信，通过 LoRa 广播您的坐标，您就可以在完全没有蜂窝网络服务的情况下看到其他人的网格位置。根据我在树林里与一小群人测试的结果，它实际上运行得相当好。<p>但让它工作起来很痛苦。BLE 文档很少，protobuf 模式在固件版本之间变化，而且除了使用官方客户端之外，基本上没有任何关于将 Meshtastic 集成到您自己的应用程序中的内容。需要大量的反复试验。<p>还有其他人基于 Meshtastic 或 LoRa 网状网络构建东西吗？传感器相关的东西、跟踪、紧急通信，等等。您的设置是什么样的，并且您那边的 BLE 稳定性如何？

Meshtastic has gotten really popular for off-grid texting but I feel like the underlying architecture (LoRa mesh + BLE relay to phone) could do a lot more than chat.<p>I added Meshtastic support to a navigation app I'm working on. Phone talks to a Meshtastic radio over BLE, pushes your coordinates out over LoRa, and you can see other people's grid positions with no cell service at all. It actually works pretty well from what I tested with a small group out in the woods.<p>Getting it working was a pain though. BLE docs are sparse, protobuf schemas shift between firmware releases, and there's basically nothing out there for integrating Meshtastic into your own app vs just using the official client. Lots of trial and error.<p>Anyone else building things on top of Meshtastic or LoRa mesh? Sensor stuff, tracking, emergency comms, whatever. What does your setup look like and how bad is the BLE flakiness on your end?
