Upstate Mesh MeshCore
¶ UM MeshCore Quick Reference
The following radio values are used on the Upstate Mesh MeshCore network
2-byte Addresses
Make sure your devices are on 1.14 or newer to prepare for 2-byte addresses. 2-byte addresses will reduce the possibility of public key collisions on the mesh.
- Frequency (MHz):
910.525 - Bandwidth:
62.5 - Spreading Factor:
7 - Coding Rate:
8
To quickly set those values via commandline:
set radio 910.525,62.5,7,8
¶ What Is MeshCore?
MeshCore is a multi platform system for enabling secure text based communications utilising LoRa radio hardware. MeshCore is a simple, secure, off-grid mesh communications system.
Build your own low-cost, long-range, encrypted messaging network.
You can still send messages even when WiFi, Cellular, and Starlink are down. - MeshCore
In short MeshCore is software that runs on various kinds of hardware that have integrated LoRa radios. In even simpler terms think of MeshCore like an operating system like Anroid or iOS and the LoRa hardware like an iPhone or Galaxy S phone.
¶ UM MeshCore
When compared to Meshtastic, MeshCore is designed to have dedicated repeater infrastructure. This backbone of well placed repeaters allows for larger areas of coverage and less congestion. Within UM we have a growing network of repeaters and we're always expanding. If you have access to a high place in the region and are interested in running a repeater, reach out to us on the #meshcore-general channel in the UM discord!
¶ Device Roles
There are a few kinds of MeshCore devices that serve different functions on the mesh network:
- Companion Bluetooth - LoRa board that pairs with a phone or computer via bluetooth to send text messages from the phone or computer over the LoRa radio.
- Companion USB - LoRa board that pairs with a phone or computer via USB to send text messages from the phone or computer over the LoRa radio.
- Repeater - A standalone LoRa board that repeats incoming packets to the wider mesh network. Often paired with strong antenna and solar pannels to run coninously outdoors.
- Room Server - Room servers store message history on them and push the stored messages to users. Room servers allow roaming users to come back later and retrieve message that were recieved while the user was out of range.
The most common devices are Companion Bluetooth/USB and Repeater. There is also the ability to configure IoT devices called sensors but we will focus on the message and communications aspects of MeshCore.
