Currently, I am doing a project and I want to ask some questions.
1. Will the iot market product become non-functionable if the Internet connection is lost (cannot connect to the their cloud)?
2. Will the above problem exist for the Rpi products?
3. If I want to do a project that, if the WIFI connection is lost for my RPi zero w, the device will automatically change to use bt to communicate with other connected gadgets. Is it possible to do this?
Thanks a lot!
