Bei der Entwicklung von IoT-Endgeräten haben die Bluetooth-Chips der nRF-Serie von Nordic seit jeher eine wichtige Position eingenommen. Unter ihnen ist die Lösung nRF51822 als frühklassisches Modell immer noch in kostengünstigen Szenarien weit verbreitet; während die nRF52832-Lösung als aktualisierte Version zur ersten Wahl für Mid-to-High-End-BLE-Produkte mit stärkerer Leistung geworden ist.

This paper focuses on the customer-proposed "4G master node + LoRa cascade relay" remote control scheme for transmission line towers. Combining technical documents of products from Chengdu Ebyte Electronic Technology Co., Ltd. (EBYTE), it conducts an in-depth analysis of the scheme's feasibility, technical implementation path, product selection recommendations, and potential advantages and challenges. The conclusion shows that the scheme is technically fully feasible, and Ebyte's existing product line can provide mature hardware support.

In complex application scenarios such as industrial IoT, smart cities, and energy monitoring, stable, reliable, and long-range data transmission is critical to system success. Leveraging its profound technical expertise, EBYTE launches the flagship product of its industrial-grade wireless data radio series—the E90-DTU(400SL42).
