Thanks for the links. I'm aware that puck is not a bangle, however since they both based on Espruino and the bangle reference includes these features then I assumed the code would be pretty cross compatible.
The characteristic and service are different - just by one character.

Could it be a 'Puck' is not a 'Bangle'?
Shouldn't the service and characteristic differ?
