This wearable device can be used as a simple GPS- which will lock its current location and publish other data via LoRa.Improvement:A compass that shows direction and distance is a great added value to the that you could consider. Meanwhile, publishing altitude, speed, or other parameters could bring more scenarios to this . Besides, the chip ESP32-C3 allowsthis to communicate over WiFi or BLE, and therefore,we can upload the 's data or realize the Long Range-to-MQTT bridge as well.
