Please use wio_3g ID for board option in “platformio.ini” (Project Configuration File):
[env:wio_3g]
platform = ststm32
board = wio_3g
You can override default Seeed Wio 3G settings per build environment using
board_*** option, where *** is a JSON object path from
board manifest wio_3g.json. For example,
board_build.mcu, board_build.f_cpu, etc.
[env:wio_3g]
platform = ststm32
board = wio_3g
; change microcontroller
board_build.mcu = stm32f439vi
; change MCU frequency
board_build.f_cpu = 180000000L
Seeed Wio 3G supports the following uploading protocols:
blackmagic
jlink
stlink
Default protocol is stlink
You can change upload protocol using upload_protocol option:
[env:wio_3g]
platform = ststm32
board = wio_3g
upload_protocol = stlink
Debugging - “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 Tools & Debug Probes using debug_tool option in “platformio.ini” (Project Configuration File).
Seeed Wio 3G has on-board debug probe and IS READY for debugging. You don’t need to use/buy external debug probe.

The ARM Cortex Microcontroller Software Interface Standard (CMSIS) is a vendor-independent hardware abstraction layer for the Cortex-M processor series and specifies debugger interfaces. The CMSIS enables consistent and simple software interfaces to the processor for interface peripherals, real-time operating systems, and middleware. It simplifies software re-use, reducing the learning curve for new microcontroller developers and cutting the time-to-market for devices |
