Before delving into the Grove Wio-E5, let's briefly understand the Wio-E5.

The Wio-E5 powered by the STM32WLE5JC, which integratis an ARM Cortex M4 ultra-low-power MCU and LoRa® RF radio SX126x into a single chip. It's a wireless RF module supporting LoRa® and LoRaWAN® protocols on EU868 and US915 frequencies, as well as (G)FSK, BPSK, (G)MSK, and LoRa® modulation. And it has obtained FCC, CE, IC and Telec certifications (For more information about Wio-E5, refer to the Wio-E5 wiki.)

The Grove Wio-E5 embeds this ultra-low-power Wio-E5. With onboard Grove connectors for easy plug-and-play integration, it provides your development board with powerful capabilities for ultra-long-range transmission.

As an upgrade of our old version - Grove - Long Range 868MHz - powered by RFM95 ultra-long-range Transceiver Module, Grove LoRa-E5 embedded with Wio-E5 STM32WLE5JC Module is a high-performance and easy-to-use wireless radio LoRa® module supporting LoRaWAN® protocol.

More comparison between the Wio-E5 and RFM95 chip:

By connecting Grove - Wio-E5 to your development boards, your devices are able to communicate with and control Wio-E5 conveniently by AT command through UART connection. Grove Wio-E5 will be 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.

Application Notes​

Note 1. Factroy AT Firmare​

Wio-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, developers 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 Wio-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 Wio-E5 Dev Board or Wio-E5 mini), the module will stay in the bootloader, and keep transmitting "C" character every 1S at baud rate 115200.

attention
  • 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.
  • The "PB13/SPI_SCK/BOOT" pin on the Wio-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 users need to be careful when developing the low-power applications.

Note 2. Clock Configuration​

2.1 HSE

  • 32MHz TCXO
  • TCXO power supply: PB0-VDD_TCXO

2.2 LSE

  • 32.768KHz crystal oscillator

Note 3. RF Switch​

Wio-E5 module ONLY transmits through RFO_HP:

  • Receive: PA4=1, PA5=0
  • Transmit(high output power, SMPS mode): PA4=0, PA5=1

Note 4. General workflow guide - Grove LoRa E5 Configuration and Usage​

Grove LoRa E5 comes with built-in LoRaWAN firmware that provides an AT server (check the LoRa-E5 AT Command Specification).

Like any non-hardcoded device, you can define every EUI and API key as needed. Refer to this workflow for more details: SenseCAP Indicator Application LoRaWAN.

The typical workflow for your product (XIAO [any microcontroller] + Grove E5) would be as follows:

  1. Register the device on the LoRaWAN Network Server to get credentials: EUI and key.
  2. Configure your LoRa E5 device to set the EUI and other parameters.
  3. Enjoy it: send and receive messages. Note: You must be covered by an accessible LoRaWAN Gateway.

For your Arduino project, we recommend this library(repository) to configure your device: andresoliva/LoRa-E5.

Ensure your LNS (LoRaWAN Network Server) is set up correctly, and verify that your credentials and LoRa parameters match.

✨ Contributor Project​

  • Thanks for one of Seeed Studio's friend Andres to build the Grove - Wio-e5 library, providing multiple examples, suitable for Arduino boards like Arduino Nano 33 BLE Sense, and more importantly compatible with the XIAO ESP32S3 Sense.
  • This will allow the user an easy, clear and safe interaction with the SeedStudio LoRa module Grove - Wio-E5 and hopefully be used as both an educational tool for those who are doing their first steps into LoRa as well as prepared for the ones looking for using this module in low-power projects.
