The Grove LoRa-E5 is a superior choice for IoT device development, testing, and long-distance, ultra-low power consumption IoT scenarios like smart agriculture, smart office, and smart industry. It is designed with industrial standards with a wide working temperature at -40℃ ~ 85℃, high sensitivity between -116.5 dBm and -136 dBm, and power output between 10 dBm and 22 dBm.

Features

  • LoRa-E5 (STM32WLE5JC) embedded
  • Support LoRaWAN protocol on EU868/US915 frequency band
  • Ultra-long transmitting range up to 10km (Ideal value in open space)
  • Easy control by AT command via UART connection
  • Rapid prototyping with plug-and-play Grove interfaces
  • Ultra-low power consumption and high performance

Grove – LoRa-E5 can endow your development boards’ strong features of ultra-long transmitting range, great performance, and high efficiency by easiliy plug and play with Grove connector on board. By connecting Grove – LoRa-E5 to your development boards, your devices is able to communicate with and control LoRa-E5 conveniently by AT command through UART connection.

1. Factory AT Firmware

LoRa-E5 series has a built-in AT command firmware, which supports LoRaWAN Class A/B/C protocol and a wide frequency plan: EU868/US915/AU915/AS923/KR920/IN865. With this AT command firmware, users can easily and quickly build their prototype or application.

The AT command firmware contains a bootloader for DFU and the AT application. The “PB13/SPI_SCK/BOOT” pin is used to control LoRa-E5 to stay in the bootloader or jump to the AT application. When PB13 is HIGH, the module will jump to AT application after reset, with a default baud rate of 9600. When PB13 is LOW (press the “Boot” button on LoRa-E5 Dev Board or LoRa-E5 mini), the module will stay in the bootloader, and keep transmitting “C” character every 1S at baud rate 115200.

Attention

1. Factory AT Firmware is programmed with RDP(Read Protection) Level 1, developers need to remove RDP first with STM32Cube Programmer. Note that regression RDP to level 0 will cause a flash memory mass to erase and the Factory AT Firmware can’t be restored again.

2. The “PB13/SPI_SCK/BOOT” pin on the LoRa-E5 module is just a normal GPIO, not the “BOOT0” pin of the MCU. This “PB13/SPI_SCK/BOOT” pin is used in the bootloader of the Factory AT firmware, to decide to jump to APP or stay in bootloader(for DFU). The real “BOOT0” pin doesn’t pinout to the module, so developers need to be careful when developing low-power applications.
