FAQ
Is the T-Echo Plus compatible with Meshtastic out of the box?
Yes, the T-Echo Plus is perfectly suited to the Meshtastic open-source ecosystem. It allows you to communicate via encrypted text messaging off-network by synchronising with your smartphone via Bluetooth.
What is the purpose of the BME280 sensor on this version?
The BME280 sensor automatically measures and broadcasts telemetry data on temperature, relative humidity and atmospheric pressure at your location across the mesh network.
What battery life can be expected from the 2400 mAh battery?
Thanks to the advanced power management of the nRF52840 microcontroller and the E-Paper display, typical battery life ranges from several days to over a week, depending on the beacon transmission interval and Bluetooth usage.
Can the original LoRa antenna be replaced?
Yes, the antenna is connected via a standard connector, allowing you to replace it with an omnidirectional or directional antenna with higher gain to increase the range.
Is this 868 MHz version legal in France and across Europe?
Absolutely; the 868 MHz frequency band is the licence-free ISM band dedicated to LoRa and IoT transmissions in France and throughout the European Union.
