Settings — Modules & Admin

Configure optional feature modules and perform device administration. Modules extend Meshtastic with specialized capabilities — each can be independently enabled or disabled.

💡 Tip: You only need to enable the modules you actually use. Disabling unused modules reduces airtime, saves battery, and simplifies your configuration.

Module settings use a card-based layout with toggle switches, dropdowns, text fields, and sliders:

Конфигурација модула

MQTT Module

Bridges mesh messages to and from an MQTT broker for internet connectivity. This is how you extend your mesh beyond radio range or integrate with home automation systems.

Setting	Опис
Омогућено	Toggle MQTT bridge
Сервер	MQTT broker address
Корисничко име	Authentication username
Лозинка	Authentication password
Encryption	Encrypt MQTT payloads
JSON Output	Publish and consume MQTT messages as JSON. Marked deprecated in the protobuf schema, but it is still the only toggle for this behavior and the firmware still honors it
TLS	Use secure connection
Корен тема	Base MQTT topic path
Proxy to client enabled	Let a connected phone carry the node's MQTT traffic, instead of the node reaching the broker itself
MQTT proxy on this phone	The phone-side half of Proxy to client enabled: whether this phone acts as that relay. See MQTT
Извештај мапе	Publish position to the public map — see below

Map Report expands into its own group:

Setting	Опис
Омогућено	Publish to the public map at all
Share location	Explicit consent to include your position. Map reporting does not save without it
Position precision	How coarsely your position is published
Publish interval	How often to report. Must be at least 3600 s (1 hour) — the app blocks saving below that

See MQTT for a detailed usage guide including encryption, privacy, and broker setup.

Serial Module

Enables serial port communication for external device integrations (GPS modules, sensors, or custom hardware). When enabled, the node's serial port can send and receive protobuf or text data, allowing external microcontrollers or computers to interact with the mesh.

Setting	Опис
Serial enabled	Activate serial communication
Echo enabled	Echo received serial data back
Serial mode	Which protocol the port speaks — Default, Simple, Proto, Text message, NMEA, CalTopo, WS85 weather station, VE.Direct, MeshSolar config, Log, or Log (text only)
RX / TX	GPIO pins for the serial connection
Serial baud rate	Port speed
Временско ограничење	How long to wait before considering an incoming message complete
Override console serial port	Take over the port the debug console normally uses

External Notification Module

Controls buzzer, LED, or vibration alerts on your radio hardware. Useful for devices that need to physically signal when a message arrives — particularly helpful for unattended or outdoor installations.

There are two independent triggers — an incoming message, and a received bell character — and each can drive the LED, the buzzer and the vibration motor separately, giving six toggles.

Setting	Опис
External notification enabled	Master toggle for the module
Alert message LED / buzzer / vibra	Which outputs fire on an incoming message
Alert bell LED / buzzer / vibra	Which outputs fire on a received bell character
Output LED (GPIO)	Pin the LED is wired to
Output LED active high	Whether the LED pin is active high or low
Output buzzer (GPIO)	Pin the buzzer is wired to
Output vibra (GPIO)	Pin the vibration motor is wired to
Use PWM buzzer	Drive the buzzer with PWM, which allows tones rather than a single pitch
Use I2S as buzzer	Send the alert through an I2S audio output instead
Output duration (milliseconds)	How long a single alert lasts
Nag timeout (seconds)	Keep repeating the alert for this long until it is acknowledged. 0 disables nagging
Мелодија звона	The tone played on a PWM buzzer, in RTTTL. Can be imported from a file

Store & Forward Module

Buffers messages for nodes that were temporarily offline, then replays them when those nodes reconnect. Essential for meshes where nodes go in and out of range regularly — ensures messages aren't lost during brief disconnections.

Setting	Опис
Омогућено	Activate store and forward
Heartbeat	Periodically announce this node's store-and-forward capability
Records	Maximum stored messages
History Return (max)	Max messages to replay
History Return (window)	Time window for replay
Сервер	Act as a store-and-forward server for the mesh (requires ample memory, e.g. ESP32 with PSRAM)

💡 Tip: Store and Forward works best on nodes with ample memory (ESP32 with PSRAM). Router nodes are ideal candidates since they're typically always-on.

Range Test Module

⚠️ Warning: Range Test only works on a secured primary channel. As long as your primary channel still uses the default channel key, the Enabled, Interval and Save-CSV controls stay disabled, and saving force-disables the module if the channel has reverted to public.

Automated range testing tool for evaluating link quality between nodes. When enabled, the node periodically transmits test messages with incrementing counters. A receiver node logs these messages, allowing you to walk or drive away and later analyze at what distance messages stopped arriving.

Setting	Опис
Омогућено	Activate range testing
Sender Interval (s)	Time between test transmissions
Save CSV	Log received test data to SD card

Telemetry Module

Controls what telemetry data your node shares with the mesh. Telemetry includes device health (battery, uptime) and environmental sensor data (temperature, humidity, pressure).

Each of the four metric groups has its own enable toggle and its own interval, so you can report battery health often and sensors rarely.

Setting	Опис
Send Device Telemetry	Master toggle for device metrics. Only shown on firmware 2.7.12 and newer
Device metrics update interval	How often to report battery, uptime and channel utilisation
Environment metrics module enabled	Report the attached environment sensors
Environment metrics update interval	How often to report them
Environment metrics on-screen enabled	Also show these readings on the device's own display
Environment metrics use Fahrenheit	Use °F on the device's display. This is the radio's screen only — the app follows your phone's locale, see Units & Locale
Air quality metrics module enabled	Report particulate and CO₂ sensor data
Air quality metrics update interval	How often to report them
Power metrics module enabled	Report the per-channel voltage and current readings
Power metrics update interval	How often to report them
Power metrics on-screen enabled	Also show power readings on the device's display

See Telemetry & Sensors for supported sensors and configuration recommendations.

Canned Message Module

Pre-configured messages accessible from the radio's physical buttons (for radios with rotary encoders, keypads, or similar input hardware). Define a list of quick-send messages that can be transmitted without a phone connected — ideal for field use.

Setting	Опис
Canned message enabled	⚠️ Deprecated in the protobuf schema
Поруке	Newline-separated list of messages
Send bell	Send a bell character alongside the message, so a receiving node's External Notification module can sound
Rotary encoder enabled	Use a rotary encoder as the input device
GPIO pin for rotary encoder A / B / press	The three pins the encoder is wired to
Generate input event on press / CW / CCW	Which key event each encoder action produces
Up/Down/Select input enabled	A separate, simpler input scheme using up/down/select buttons rather than an encoder
Allow input source	⚠️ Deprecated in the protobuf schema

Audio Module

Codec2 audio support for low-bandwidth voice communication over the mesh. This is an experimental feature that encodes voice into very small data packets using the Codec2 codec.

Setting	Опис
Омогућено	Activate audio module
Codec2 Rate	Audio quality/bandwidth tradeoff
PTT Pin	GPIO pin for the push-to-talk button
I2S Word Select	GPIO pin for I2S WS
I2S Data In	GPIO pin for I2S DIN
I2S Data Out	GPIO pin for I2S DOUT
I2S Clock (SCK)	GPIO pin for the I2S bit clock

ℹ️ Note: Audio requires specific hardware (I2S microphone and speaker). Voice quality is very low-bandwidth — think "understandable radio voice," not phone-call quality.

Remote Hardware Module

GPIO control over the mesh network. Allows a remote node to read or write GPIO pins on another node — useful for activating relays, reading switches, or controlling external hardware from a distance.

⚠️ Warning: Enabling Allow Undefined Pins gives remote nodes access to all GPIO pins, which could interfere with the radio's own hardware. Only enable on dedicated GPIO nodes.

Setting	Опис
Омогућено	Activate remote GPIO access
Allow Undefined Pins	Allow access to any GPIO pin (security risk)
Available Pins	Up to 4 GPIO pins this node exposes for remote read/write

Neighbor Info Module

Broadcasts information about directly heard neighbors, enabling mesh topology mapping. Each enabled node periodically shares a list of the other nodes it can hear and their signal quality.

Setting	Опис
Омогућено	Activate neighbor broadcasting
Update Interval (s)	How often to broadcast neighbor list
Transmit Over LoRa	Also broadcast neighbor info over LoRa, not just MQTT/phone. Unavailable on a channel using the default key and name

See Local Mesh Discovery for how to use neighbor data for mesh topology exploration.

Ambient Lighting Module

Controls onboard NeoPixel or other addressable RGB LEDs on supported hardware. Can be used for visual status indicators, notification lights, or decorative effects.

Setting	Опис
LED статус	Turn the LED on or off
Струја	LED current limit (0–31)
Red / Green / Blue	Individual color channel values (0–255)

Detection Sensor Module

Turns your node into a motion or door sensor alert system. When a GPIO pin detects a state change (motion detected, door opened), the node broadcasts an alert message over the mesh.

Setting	Опис
Омогућено	Activate detection sensor
Monitor Pin	GPIO pin connected to sensor
Detection Trigger Type	How the pin's state maps to a detection event (e.g. active high/low, edge-triggered)
Use Input Pullup Mode	Enable the pin's internal pull-up resistor
Minimum Broadcast (s)	Minimum time between alert broadcasts
State Broadcast (s)	Periodic state broadcast interval
Пошаљи звоно	Include bell character in alerts
Friendly Name	Custom name for this sensor

Paxcounter Module

People counter using Wi-Fi and BLE probe requests. Counts nearby devices by passively listening for probe requests that phones and laptops emit when scanning for networks. Available only on ESP32 devices.

Setting	Опис
Омогућено	Activate people counting
Update Interval (s)	How often to report counts
Wi-Fi RSSI threshold	Ignore Wi-Fi probes weaker than this, so distant devices are not counted (defaults to −80 dBm)
BLE RSSI threshold	The same cut-off for BLE advertisements (defaults to −80 dBm)

💡 Tip: Paxcounter is useful for estimating foot traffic at trailheads, event venues, or other locations. Counts are approximate — one person may carry multiple devices.

Status Message Module

The status message has no module screen. It is edited with the rest of the node's identity, on Settings — Radio & User.

Mesh Beacon Module

Broadcasts an invitation to your mesh, and receives invitations from others. See Local Mesh Discovery for the full walkthrough.

TAK Module

Team Awareness Kit integration for interoperability with ATAK and WinTAK. This module only appears in the list once the node's Device Role (Device Config) is set to TAK or TAK Tracker — change the role first, otherwise the entry does not appear. See TAK Integration for detailed setup and usage.

Администрација

Удаљена администрација

Remotely configure nodes that share your admin key:

1. Select the target node in the node list.
2. Navigate to Settings for that node.
3. Modify configuration.
4. Tap Save — changes are sent over the mesh.

⚠️ Important: Requires an admin key configured on both your node and the target node.

Clean Node Database

Prunes your local node database. Two independent controls:

• An age slider — remove nodes not heard from within that window.
• Clean unknown nodes only — restrict the purge to nodes that never sent their user info, leaving named nodes alone regardless of age.

Ресетовање на фабричка подешавања

⚠️ Warning: Factory reset erases all settings, channels, and keys. This cannot be undone.

Resets all settings to factory defaults.

Поновно покретање

Remotely reboot a connected or administered node.

Панел за отклањање грешака

Opens the Packets and App logs tabs for viewing, filtering, and exporting diagnostic output. See Debug Logs for the full walkthrough.

О

Settings → About carries the app's own identity rather than the radio's:

Three sections:

• What is Meshtastic? — a short description of the project.
• Apps — opens with Need Hardware?, a rotating carousel of popular devices that links out to where to buy one. It also lists the GitHub repository, the running app version, and Acknowledgements (see the next section).
• Project information — links to the website and to this documentation.

Acknowledgements

Reached from About, this lists every open-source library the app ships, with its license, generated at build time by AboutLibraries. It was previously called the license screen.

Troubleshooting Remote Admin

• "No response from target node" — the target may be out of range, offline, or have a mismatched admin key. Verify the admin key matches on both nodes.
• Changes not applying — some settings require a reboot to take effect. Try the Reboot action after saving.
• Can't see remote settings — ensure your node has the admin key for the target node. The admin channel is configured automatically when an admin key is set.
