Using a Seeed Studio Xiao NRF52840 for ANT+ Communications

Hello everyone :grin:

I am currently undergoing a project where I am using a Bike Speed and Cadence sensor to decide gear position.

The sensor uses ANT+ communication and naturally I chose the Seeed Studio Xiao NRF52840 as it uses a chip that can interact with the ANT+ signals. I have additionally found the ANTPLUS library which should aide in development.

I have found so far that I cannot run any example code as I end up with an error referring to ‘derp’.

I have also found that there have been similar attempts to remedy this, as one must load a softdevice onto the MCU itself using a programmer to get it working.

If anyone has successfully loaded a softdevice onto a XIAO or has any experience or knowledge in this area, please could you help point me in the right direction in terms of resources and how you did so?

Cheers

Hi there,
and Welcome here,

Ah’ the ANT+ protocol used by other companies also but Garmin I believe owns it. There are some old threads where a gentleman purchased the ANT+ as it’s not open source. You’ll need to change the softdevice for the room to fit it as well as a bootloader if I recall.
Serch “ANT+” should yield some useful Info.
