I don't see any mention of firmware update at all on that page.

Even if it does support firmware update, that doesn't necessarily mean it will use Nordic's implementation.

A commercial product is likely to have protection in place to prevent you from loading "unauthorised" firmware ...

I have a very cheap one. Here is the link. www.amazon.com/.../ref=mp_s_a_1_1

It says it uses over the air DFU. Just not sure how to put it in that mode. Can I cheat and just solder some pins from the nRF chip together or something like that?

Hi,

What fitness tracker do you have?

Is there a way to put it in DFU mode? if not, the fitness tracker you have probably doesn't support DFU.

I have figured out how to use the Nordic tools app. Now I’m not sure what the error, “Error DFU service not found” means. Any thoughts.
