Meshtastic.TAK (C#)

The .NET binding of the TAKPacket-SDK: convert ATAK Cursor-on-Target (CoT) XML to Meshtastic's TAKPacketV2 protobuf and compress it with zstd dictionary compression for LoRa mesh transport (237-byte MTU, port 78). Payloads are byte-interoperable with the Kotlin, Swift, Python, and TypeScript bindings.

Install

dotnet add package Meshtastic.TAK

Compress and decompress

using Meshtastic.TAK;

var parser = new CotXmlParser();
var compressor = new TakCompressor();
var builder = new CotXmlBuilder();

// Compress
var packet = parser.Parse(cotXmlString);
byte[] wirePayload = compressor.Compress(packet);   // [flags byte][zstd body], ≤ 237 B

// Decompress
var received = compressor.Decompress(wirePayload);
string cotXml = builder.Build(received);
