Application

The Seeed Studio Wio-E5 TM32WLE5JC Wireless Module is commonly used in long-range IoT sensor networks, especially where stable LoRa communication is required.

• A common Lora usage scenario is building a long-range sensor network. A large
  number of sensors in the industry are transmitted through CAN Bus. For instance, the Seeed Studio MR60BHA1 Heartbeat Detection Sensor can be integrated into such networks to monitor vital data and transmit it via LoRaWAN. With the Wio-E5 CANBus Dev board, you can use the on-board CAN Bus function to read the sensors, and send the data through Long Range
• Since the circuit board can receive 5-28V input, the user can connect the circuit board to the OBD interface, get the data of the car, and send it out through Long Range.

Application

Factory AT Firmware

• Wio-E5 series has a built-in AT command firmware, which supports LoRaWAN Class A/B/Cprotocol and a wide frequency plan: EU868/US915/AU915/AS923/KR920/IN865. With this ATcommand 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 ATAT 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.

Clock Configuration

 HSE

Develop with STM32Cube MCU Package

The Seeed Studio Wio-E5 TM32WLE5JC Wireless Module can be developed easily using the STM32Cube MCU Package for the STM32WL series.

This section is for the Wio-E5 Mini or Wio-E5 Dev Board, aiming at creating a LoRaWAN End Node with the STM32Cube MCU Package for the STM32WL series(SDK), to join and send data to the LoRaWAN Network.

Preparations

Hardwares

• LoRaWAN Gateway connected to LoRaWAN Network Server(e.g., TTN)
• Prepare a USB Type-C cable and an ST-LINK. Connect the Type-C cable to the Type-C port for power and serial communication  and connect the ST-LINK to the SWD pins like this:

GPIO Configuration Overview

As the hardware design of the Wio-E5 series is a bit different from NUCLEO-WL55JC, the official STM32WL55JC development board from ST, developers need to reconfigure some GPIOs, to adapt the SDK example to the Wio-E5 series. We have already reconfigured gpios in this example, but we think itis  necessary to point out the difference.

Build the LoRaWAN End Node Example

• Download and copy this repo to your SDK folder. stm32cubewl\SIM32Cube_FW_WL_V1.0.0\Projects\NUCLE0-| VL55JC\Applications\LoRaWAN and replace the original en. stm32cubewl\STM32Cube_FW_WL_V1.0.0\Projects\NUCLE0- WL55JC\Applications\LoRaWAN\LoRaWAN_End_ Node folder
• Open the LoRaWAN_End _Node example with sTM32CubeIDE, by double click file LoRaWAN_End_Node\STM32CubeIDE\.project
• Click Build Debug for this example; it should work without any errors.

Application KEY, and your LoRaWAN Region

Modify your Device EUI, Application EUI,  Application KEY, and your LoRaWAN Region

• Please follow the guide here to set up your TTN application, get yourApplicationl and copy it to the macro definition LORAWAN_JOIN_EUI in LoRaWAN/App/se-identity.h, for example, my Application EUI is 70 B3 DS 7E DO 03 FO 6A.

• Also, you can modify your DeviceEUI and Application Key, b setting the macro definition LORALORAWAN_DEVICE_EUI LORAWLORAWAN_NWK_KEYoRaWAN/App/se-identity.h, don’. Don’tt to ensure LOLORAWAN_DEVICE_EUInd LOLORAWAN_NWK_KEYre the same as the Device BUI and App Key in the TTN console.

• The default LoRaWAN Region is EU868; you can modify it by setting the macro definition ACTIVE REGION in LoRaWAN/App/lora app.h

• After modification, please rebuild the example and program for your Wio-E5. Open STM32CubeProgrammer, connect ST-LINK to your PC, hold the RESET Button of your Device, then click connect and release the RESET Button.

• Make sure the Read Out Protection is AA. If it is shown as BB, select AA and click Apply.

• Now, go to the Erasing & Programming page, select your hex file path(my path is
  E: \en.stm32cubewl\STM32Cube_FW_WL_V1.0.0\Projects\NUCLB0-|  WLSSJC\Applications\LoRaWAN\LoRaWAN_End_Node\STM32CubeIDE\LoRaWAN_End_Node_D_ End Node_D ebug. hex ), select the programming options as the following picture, then click Start Programming! Oncethe  programming is finished,

• If your LoRaWAN Gateway and TTN are set up, Wio-E5 will join successfully after a reset! A Acomfirm LoRaWAN package will be sent to TTN every 30 seconds. The following log will come out from the serial port if the join is successful:

• Cheers! You have already connected Wio-E5 to the LoRaWAN Network! Can’t wait to see you develop some wonderful LoRaWAN End Node applications!

Application Notes

Wio-E5 only supports high power output mode, so you can’t use these macro definitions in radio_board_if.h
