Seeed Arch BLE

Hardware

Platform Nordic nRF51: The Nordic nRF51 Series is a family of highly flexible, multi-protocol, system-on-chip (SoC) devices for ultra-low power wireless applications. nRF51 Series devices support a range of protocol stacks including Bluetooth Smart (previously called Bluetooth low energy), ANT and proprietary 2.4GHz protocols such as Gazell.

Microcontroller NRF51822
Frequency 16MHz
Flash 128KB
RAM 16KB
Vendor SeeedStudio

Configuration

Please use seeedArchBLE ID for board option in “platformio.ini” (Project Configuration File):

[env:seeedArchBLE]
platform = nordicnrf51
board = seeedArchBLE

You can override default Seeed Arch BLE settings per build environment using board_*** option, where *** is a JSON object path from board manifest seeedArchBLE.json. For example, board_build.mcu, board_build.f_cpu, etc.

[env:seeedArchBLE]
platform = nordicnrf51
board = seeedArchBLE

; change microcontroller
board_build.mcu = nrf51822

; change MCU frequency
board_build.f_cpu = 16000000L

Uploading

Seeed Arch BLE supports the next uploading protocols:

  • blackmagic
  • cmsis-dap
  • jlink
  • mbed
  • nrfjprog
  • stlink

Default protocol is cmsis-dap

You can change upload protocol using upload_protocol option:

[env:seeedArchBLE]
platform = nordicnrf51
board = seeedArchBLE

upload_protocol = cmsis-dap

Debugging

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 Arch BLE has on-board debug probe and IS READY for debugging. You don’t need to use/buy external debug probe.
