PortNum

Admin control packets.
Payload is a AdminMessage message.
ENCODING: Protobuf

Same as Text Message but used for critical alerts.

ATAK Forwarder Module https://github.com/paulmandal/atak-forwarder
ENCODING: libcotshrink

ATAK Plugin
Portnum for payloads from the official Meshtastic ATAK plugin

Audio Payloads.
Encapsulated codec2 packets. On 2.4 GHZ Bandwidths only for now
ENCODING: codec2 audio frames
NOTE: audio frames contain a 3 byte header (0xc0 0xde 0xc2) and a one byte marker for the decompressed bitrate.
This marker comes from the 'moduleConfig.audio.bitrate' enum minus one.

App for transporting Cayenne Low Power Payload, popular for LoRaWAN sensor nodes. Offers ability to send
arbitrary telemetry over meshtastic that is not covered by telemetry.proto
ENCODING: CayenneLLP

Same as Text Message but originating from Detection Sensor Module.
NOTE: This portnum traffic is not sent to the public MQTT starting at firmware version 2.2.9

Used for the python IP tunnel feature
ENCODING: IP Packet. Handled by the python API, firmware ignores this one and pases on.

Module/port for handling key verification requests.

Provides unencrypted information about a node for consumption by a map via MQTT

Currently we limit port nums to no higher than this value

Aggregates edge info for the network by sending out a list of each node's neighbors
ENCODING: Protobuf

The built-in user info app.
Payload is a User message.
ENCODING: Protobuf

Paxcounter lib included in the firmware
ENCODING: protobuf

The built-in position messaging app.
Payload is a Position message.
ENCODING: Protobuf

PowerStress based monitoring support (for automated power consumption testing)

Private applications should use portnums >= 256.
To simplify initial development and testing you can use "PRIVATE_APP"
in your code without needing to rebuild protobuf files (via [regen-protos.sh](https://github.com/meshtastic/firmware/blob/master/bin/regen-protos.sh))

Optional port for messages for the range test module.
ENCODING: ASCII Plaintext
NOTE: This portnum traffic is not sent to the public MQTT starting at firmware version 2.2.9

Reserved for built-in GPIO/example app.
See remote_hardware.proto/HardwareMessage for details on the message sent/received to this port number
ENCODING: Protobuf

Provides a 'ping' service that replies to any packet it receives.
Also serves as a small example module.
ENCODING: ASCII Plaintext

Reticulum Network Stack Tunnel App
ENCODING: Fragmented RNS Packet. Handled by Meshtastic RNS interface

Protocol control packets for mesh protocol use.
Payload is a Routing message.
ENCODING: Protobuf

Provides a hardware serial interface to send and receive from the Meshtastic network.
Connect to the RX/TX pins of a device with 38400 8N1. Packets received from the Meshtastic
network is forwarded to the RX pin while sending a packet to TX will go out to the Mesh network.
Maximum packet size of 240 bytes.
Module is disabled by default can be turned on by setting SERIAL_MODULE_ENABLED = 1 in SerialPlugh.cpp.
ENCODING: binary undefined

Used to let multiple instances of Linux native applications communicate
as if they did using their LoRa chip.

ENCODING: Protobuf (?)

STORE_FORWARD_APP (Work in Progress)
Maintained by Jm Casler (MC Hamster) : jm@casler.org
ENCODING: Protobuf

Provides a format to send and receive telemetry data from the Meshtastic network.
Maintained by Charles Crossan (crossan007) : crossan007@gmail.com
ENCODING: Protobuf

A simple UTF-8 text message, which even the little micros in the mesh
can understand and show on their screen eventually in some circumstances
even signal might send messages in this form (see below)
ENCODING: UTF-8 Plaintext (?)

Compressed TEXT_MESSAGE payloads.
ENCODING: UTF-8 Plaintext (?) with Unishox2 Compression
NOTE: The Device Firmware converts a TEXT_MESSAGE_APP to TEXT_MESSAGE_COMPRESSED_APP if the compressed
payload is shorter. There's no need for app developers to do this themselves. Also the firmware will decompress
any incoming TEXT_MESSAGE_COMPRESSED_APP payload and convert to TEXT_MESSAGE_APP.

Provides a traceroute functionality to show the route a packet towards
a certain destination would take on the mesh. Contains a RouteDiscovery message as payload.
ENCODING: Protobuf

Deprecated: do not use in new code (formerly called OPAQUE)
A message sent from a device outside of the mesh, in a form the mesh does not understand
NOTE: This must be 0, because it is documented in IMeshService.aidl to be so
ENCODING: binary undefined

Waypoint payloads.
Payload is a Waypoint message.
ENCODING: Protobuf

Experimental tools for estimating node position without a GPS

ENCODING: arrays of int64 fields
