RAK811 LoRa Tracker

Contents

Hardware

Platform :ref:`platform_ststm32`: The STM32 family of 32-bit Flash MCUs based on the ARM Cortex-M processor is designed to offer new degrees of freedom to MCU users. It offers a 32-bit product range that combines very high performance, real-time capabilities, digital signal processing, and low-power, low-voltage operation, while maintaining full integration and ease of development.

Microcontroller STM32L151RBT6
Frequency 32MHz
Flash 128KB
RAM 32KB
Vendor RAK

Configuration

Please use rak811_tracker_32 ID for :ref:`projectconf_env_board` option in :ref:`projectconf`:

[env:rak811_tracker_32]
platform = ststm32
board = rak811_tracker_32

You can override default RAK811 LoRa Tracker settings per build environment using board_*** option, where *** is a JSON object path from board manifest rak811_tracker_32.json. For example, board_build.mcu, board_build.f_cpu, etc.

[env:rak811_tracker_32]
platform = ststm32
board = rak811_tracker_32

; change microcontroller
board_build.mcu = stm32l151rbt6

; change MCU frequency
board_build.f_cpu = 32000000L

Uploading

RAK811 LoRa Tracker supports the following uploading protocols:

  • blackmagic
  • cmsis-dap
  • jlink
  • serial
  • stlink

Default protocol is stlink

You can change upload protocol using :ref:`projectconf_upload_protocol` option:

[env:rak811_tracker_32]
platform = ststm32
board = rak811_tracker_32

upload_protocol = stlink

Debugging

:ref:`piodebug` - "1-click" solution for debugging with a zero configuration.

Warning

You will need to install debug tool drivers depending on your system. Please click on compatible debug tool below for the further instructions and configuration information.

You can switch between debugging :ref:`debugging_tools` using :ref:`projectconf_debug_tool` option in :ref:`projectconf`.

RAK811 LoRa Tracker does not have on-board debug probe and IS NOT READY for debugging. You will need to use/buy one of external probe listed below.

Compatible Tools On-board Default
:ref:`debugging_tool_blackmagic`   Yes
:ref:`debugging_tool_cmsis-dap`    
:ref:`debugging_tool_jlink`    
:ref:`debugging_tool_stlink`
