ST LoRa® IoT tracker - STEVAL-STRK01

End Devices (Nodes)
64

Following this thread and various sources online, I have manged to get the tracker going without compiling the firmware using the following method:

  1. Download latest firmware package from ST: https://www.st.com/content/st_com/en/products/embedded-software/mcu-mpu-embedded-software/stm32-embedded-software/stm32-ode-function-pack-sw/fp-atr-lora1.html
  2. Download the ST-link utility for flashing: https://www.st.com/en/development-tools/stsw-link004.html
  3. Connect as shown at the end of this document to ST-Link programmer/Nucleo board as shown earlier in this thread.
  4. I have had to connect battery, USB cable and the programmer for the flashing to be successful, did not work without the USB cable and only on battery
  5. Use the ST-Link flasher utility by selecting Program & Verify and select the file from the downloaded software package: /STM32CubeFunctionPack_LORA1_V2.0.1/Projects/STEVAL-STRKT01/Applications/LoRa/Asset_Tracker/Binary/STEVAL_STRKT01.bin
  6. Create an application on TTN and register a new node. I have opted for a TTN generated DevEUI, you could get one from the tracker as well.
  7. Provision the tracker through the serial connection (tested under Windows and Linux, just plug in and port should appear) with the following commands (copy/paste replacing xxxxx with string from TTN console):
  • TTN provided DevEUI, likely you could use board provided one, but need to load different FW to find it out or observe on GW
     !deviceeui-xxxxxx
  • TTN provided Application EUI
     !joineui-xxxxxx
  • TTN provided App key
    !appkey-xxxxxx
  • TTN provided App key
     !ntwkkey-xxxxxx
  • Issue a reset to use this keys
     !sysreset
  1. On TTN under payload formats configure the Cayenne LPP and you will get decoded data.
  2. If all has gone well, the tracker should be connected and sending data.
