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.

Component Datasheet

A lot of thanks for all your valuable labor on this blog. My mom takes pleasure in setting aside time for investigation and it's easy to see why. My spouse and i hear all concerning the powerful way you present simple guidelines by means of your website and as well strongly encourage response from some other people on that concern then our own princess has always been being taught a whole lot. Enjoy the rest of the new year. Your doing a fabulous job.

There are some attention-grabbing closing dates on this article but I don抰 know if I see all of them middle to heart. There's some validity however I'll take hold opinion till I look into it further. Good article , thanks and we wish more! Added to FeedBurner as nicely

There are definitely a lot of particulars like that to take into consideration. That could be a great level to bring up. I provide the ideas above as general inspiration however clearly there are questions like the one you deliver up where an important factor will probably be working in honest good faith. I don?t know if finest practices have emerged around things like that, however I'm certain that your job is clearly identified as a fair game. Each boys and girls really feel the impact of only a second抯 pleasure, for the rest of their lives.
