Bluetooth Low Energy 5.0 Compatible FMLR STM SX1280 LoRa IoT Modules for Wireless Connectivity with High Data Rates

FMLR-8x-x-STLx Module from Miromico

New FMLR-8x-x-STLx LoRa IoT modules from Miromico have been introduced for running full compatible Bluetooth Low Energy (BLE) 5.0 stack using Semtech’s 2.4 GHz SX1280 LoRa transceiver. These new modules are designed for applications including track and trace, building automation, construction monitoring, mining, farming, telemetry, remote data logging, etc.


Semtech’s LoRa 2.4 GHz technology used in Miromicro allows the firmware platform to run multiple wireless protocols such as LoRa and BLE 5.0 under the same microcontroller. By combining both technologies in the same wireless module, the device enables commissioning, configuration, local data monitoring, or firmware-update of IoT devices using smartphones, tablets, car navigation systems, or other iOS or Android-based devices. After the initialization process, it operates LoRa 2.4 GHz long-range applications anywhere in the world.


The FMLR-8x-x-STLx module-family comes with various options like extra onboard flash memory to enable Over-the-Air (OTA) updates and local data buffering in times when cloud connectivity is temporarily unavailable. The Micro Edge 2.4 GHz LoRa gateways allow the modules to support Semtech’s meter-accuracy, active-radar-based ranging and localization technology for both indoor and outdoor environments.


The module’s firmware can be updated via WD, UART Bootloader, or optional Firmware Over-the-Air (FOTA) to support fast prototyping and development.
