FAQ
Is the T-Echo Plus natively compatible with Meshtastic?
Yes, the T-Echo Plus is perfectly suited for the Meshtastic open-source ecosystem. It allows for encrypted off-network text messaging by syncing with your smartphone via Bluetooth.
What is the purpose of the BME280 sensor in this version?
The BME280 sensor automatically measures and broadcasts telemetry data—including temperature, relative humidity, and atmospheric pressure at your location—over the mesh network.
What kind of battery life can you expect 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 Europe?
Absolutely. The 868 MHz frequency band is a license-exempt ISM band dedicated to LoRa and IoT transmissions in France and throughout the European Union.
