Well, the use case is that I have a puck acting as a sensor (say a movement sensor attached to a door or temperature/light measurement) which is powered by the coin battery and lasts for months/years. I need to send the sensor results to something (a gateway) for further processing and/or recording that may require sending data to a cloud service - it will be powered by mains (or solar). That 'something' needs to have BLE to communicate with the puck as well as whatever other connectivity (eg HTTP) is needed.
A raspberry pi would fit the bill quite well - but so would an espruino powered device with BLE + wifi - and be much simpler to programme!
Attaching the wifi directly to the puck will require more power and negates the advantages of the long life that the puck currently enjoys...
Just a thought...
cheers...
