Waveshare BLE400¶

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.

Configuration¶

Please use waveshare_ble400 ID for board option in “platformio.ini” (Project Configuration File):

[env:waveshare_ble400]
platform = nordicnrf51
board = waveshare_ble400

You can override default Waveshare BLE400 settings per build environment using board_*** option, where *** is a JSON object path from board manifest waveshare_ble400.json. For example, board_build.mcu, board_build.f_cpu, etc.

[env:waveshare_ble400]
platform = nordicnrf51
board = waveshare_ble400

; change microcontroller
board_build.mcu = nrf51822

; change MCU frequency
board_build.f_cpu = 32000000L

Uploading¶

Waveshare BLE400 supports the following uploading protocols:

• blackmagic

• jlink

• nrfjprog

• stlink

Default protocol is jlink

You can change upload protocol using upload_protocol option:

[env:waveshare_ble400]
platform = nordicnrf51
board = waveshare_ble400

upload_protocol = jlink

Debugging¶

Debugging - “1-click” solution for debugging with a zero configuration.

You can switch between debugging Tools & Debug Probes using debug_tool option in “platformio.ini” (Project Configuration File).

Waveshare BLE400 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.
