What's New in Meshtastic

2.7.26

October 27, 2026

New - Estimate Coverage now runs on your device instead of the online site planner. Terrain downloads once, estimates inside your offline maps work without a connection, and a new receiver height setting plans for nodes on a roof or mast. - Weather radar on the map in the lower 48 states. Turn it on in Map settings. - Import KML and KMZ map files from Google Earth, CalTopo and other tools. - Place a radio's 3D model on a table at its real size from node details, and meet Chirpy. - The Live Activity row on Connect is now Widgets: the Live Activity, Home Screen and Lock Screen widgets and controls in one place. - Node details show a node's long name when you have given it a display name. Improvements - Offline Maps has an Import row for MBTiles and PMTiles files. - MQTT root topics can use letters like æ, ø and å. - 3D device models have a gray backdrop in dark mode, so black radios stand out. - The connected radio box on Connect keeps the preset on one line. - The connection indicator fits on the open iPhone Duo. - Updated device images and hardware list. Fixes - Fixed a crash in the node list when a node's position changed while the app was in the background. - The Local Stats log and the Trace Route log no longer freeze the app. - The app no longer freezes on Connect while the radio's node list downloads. - The banner for nodes not heard on the current LoRa settings stays hidden after you choose Keep. - The powered and charging battery labels no longer read as "password" and "change" in German, French, Portuguese, Japanese and Chinese.

Where is the power TX setting

The new update seems to have removed the extremely useful power Tx button

Waiting on a fix

App won’t even open at this point

Buggy

Generally has worked, but is very difficult to switch between nodes or to change programming on a node.

Recently it won't connect at all to a node. Just hangs, then closes.

Black Screen And Craahes

Was working I don’t know what you guys did but I’m only getting a black screen then it crashes.

Broken

Won’t launch as others have said, iPhone 17

FAQ

What is Meshtastic?

Meshtastic is an open-source application that creates a decentralized, off-grid mesh network using low-power LoRa radios. It allows users to send text messages without relying on traditional cellular or WiFi infrastructure.

How does Meshtastic work?

The app leverages LoRa radios to establish a mesh network, meaning devices can relay messages for each other. This creates a decentralized communication system that can extend beyond direct line-of-sight and function in areas with no internet or cell service.

Is Meshtastic free to use?

Yes, Meshtastic is an open-source project and is free to download and use. There are no in-app purchases or advertisements associated with the application itself.

What are the main use cases for Meshtastic?

Meshtastic is ideal for situations where reliable communication is critical but traditional networks are unavailable. This includes outdoor activities like hiking and camping, emergency preparedness, and communication in remote or disaster-stricken areas.
