Introduction

LR62E LoRa transceiver module uses a Semtech SX1262 sub-GHz radio transceiver. An u.FL connector is on-board for external antenna. It is paired with Fanstel BM833, a low cost Nordic nRF52833 BLE 5.2 module. The Cortex M4F MCU in BM833 manages LR62E through SPI interface. BM833 GPIOs can be used for sensor data input or control output. Android OS app is available for field set up through Bluetooth interface. BM833 + LR62E pair can be used in LoRaWANTM application. LoRaWan stacks are not available from Fanstel. In the 2nd application example, BM833 in a gateway relays messages to a cloud server (AWS, Microsoft, Google, Fanstel development server, etc.) through Ethernet, WiFi, or LTE network. LR62E LoRa module with Semtech SX1262 transceiver are ideal for long range wireless applications. It can be paired with BM833 BLE module in LoRa sensor or beacon design. A smart phone can set up sensor or beacon easily through Bluetooth interface. BM833 is powerful, highly flexible, ultra low power Bluetooth Low Energy (BLE) modules using Nordic nRF52833 SoCs. With an ARM CortexTM M4F MCU, available 512KB flash, 128KB RAM, embedded 2.4GHz multi-protocol transceiver, and an integrated antenna, it allows faster time to market with reduced development cost. The second application example is in a gateway for connecting to cloud server. A LoRa sensor or beacon can be connected to a cloud server through Ethernet, WiFi, or LTE network. It is possible to port LoRaWANTM stacks to Nordic nRF52 BLE SoCs. LoRaWANTM stacks are not available from Fanstel.
