Off-Grid Mesh Messaging
Send text over LoRa without cellular service.
Radioddity Nodara · Meshtastic LoRa Communicator
Nodara brings Meshtastic text and location sharing into a complete handheld, with a 2.13-inch E-Ink display, a 2500mAh rechargeable battery and an IP67-rated enclosure. Pair it with the Meshtastic mobile app to compose messages and configure your network, while Nodara handles the LoRa radio connection.
Keep in touch with compatible devices on a hike, around a campsite or across a local mesh. No cellular connection is needed for local radio messaging, but both ends still need compatible hardware, matching settings and radio coverage.

Live voice communication.
Push-to-talk over cellular networks.
Text messaging and location sharing over a LoRa mesh.
Nodara uses a Radioddity-exclusive enclosure with a separate power button, four direction buttons and A/B function buttons. The layout gives the screen and controls their own space, with no exposed development board to assemble.
Built-in GNSS supports GPS, GLONASS and BeiDou. Share position updates through the mesh so compatible devices can receive your location. Position reception and update settings affect what others can see.
Use the 2.13-inch E-Ink display to check incoming information on the device. Electronic paper suits short text and status pages; it is not a fast-refresh phone screen or a full navigation display.
The nRF52840 platform and 2500mAh battery combine in a self-contained handheld. GPS activity, Bluetooth, message traffic and the installed firmware all affect actual runtime.
Recharge from a USB power source. For compatible firmware recovery and updates, Nodara also supports a USB bootloader workflow. Follow the instructions supplied with the exact firmware package.
The IP67-rated enclosure keeps dust out and protects against temporary immersion in water up to 1m deep for 30 minutes. Keep the USB-C port cover closed when outdoors.
Pair your phone with Nodara to configure your mesh, manage devices and send messages.
F-Droid is another Android option when Google Play is unavailable. The Web Client works best in Chrome or Edge; browser Bluetooth support varies.
Install the Meshtastic app, power on Nodara and select the matching device in the app. Choose the correct radio region and agree on compatible settings with your group.
Type on your phone and send through Nodara over LoRa. Use a configured channel for group messages or compatible direct messaging for one-to-one conversations.
Read received information on the device or in the app. Mesh relays can help where a suitable path exists; they do not guarantee coverage or delivery.
For detailed setup, configuration and troubleshooting, visit the official Meshtastic documentation.
Your phone connects to Nodara over Bluetooth. Nodara sends messages over LoRa, and compatible nodes can pass packets onward when a relay path is available.
The diagram illustrates two possible paths. Actual routing depends on node placement, radio coverage and compatible settings.
These two direct-link examples show how distance changes with the environment, antenna setup and radio settings.

1 × Radioddity Nodara
A phone running the Meshtastic app is the recommended way to configure the device and compose text. You can view received information on the built-in display. The documented custom interface also includes preset replies and a virtual keyboard, but these functions depend on the firmware installed.
Nodara is intended for short text and small data such as positions. It is not a voice walkie-talkie, satellite phone or general internet connection.
Each end needs a compatible Meshtastic radio or access to a suitable compatible node. A phone alone cannot transmit LoRa messages. Radios need matching region, modem and channel settings, and a usable radio path.
Range depends on terrain, buildings, antenna placement, radio settings and available relay nodes. There is no single guaranteed distance. Extra nodes help only when their placement and configuration provide a usable path.
Local LoRa messaging does not require cellular service or a monthly airtime plan. Install the app and prepare your configuration before leaving coverage. Internet gateways and online map services are separate features and may require a connection.
Meshtastic supports encryption, but privacy depends on your channel keys, direct-message configuration and firmware. Default or publicly shared channel keys should not be treated as private. Follow the official security and channel-configuration guidance.
It can communicate with compatible Meshtastic devices when their radio region, frequency settings, modem preset and channel configuration match. It does not automatically communicate with FRS, GMRS, analog ham or satellite radios.
MeshCore operation is not confirmed for Nodara. Open-source firmware and a compatible chipset do not establish support for another operating system, its display driver or its controls. Use only a Nodara-specific supported package.
No. Nodara ships with the official Meshtastic firmware. Download the Nodara-developed enhanced firmware from the Radioddity download area for additional functions. Review the feature and language list for your chosen version, then follow its installation instructions. Phone-app languages are separate from on-device fonts and menus.
The battery capacity is 2500mAh. Actual runtime changes with GPS use, Bluetooth, display activity, radio traffic and firmware. Capacity and low-power hardware alone do not guarantee a fixed number of days.
Nodara is rated IP67: dust-tight and protected against temporary immersion in water up to 1m deep for 30 minutes. Keep the USB-C port cover closed during use and the connection dry before charging.
Visit the Radioddity download area for the Nodara enhanced firmware, version-specific feature list and step-by-step flashing and usage instructions. Choose the package for your device and check its release or beta status. The GitHub development branch provides source code separately; it is not the same as a ready-to-install update.
Electronic paper can retain an image without refreshing. A paused or retained screen image alone does not establish whether the device is currently on, connected or receiving. Check the controls and indicator behavior described in the manual for your installed version.
It can share positions with compatible nodes and display location-related information supported by its firmware. That does not provide guaranteed navigation, an emergency dispatch service or assured message delivery. Plan your route and backup communications separately.
Use the version and radio configuration permitted for your country. The manual lists US 915MHz and EU 868MHz operation. A selectable frequency does not make every setting legal in every country; permitted power and airtime rules also apply.
