Hello,
I am thinking of implementing a project in which if we use NFC to perform Bluetooth quick pairing and create a Bluetooth connection between a phone and a Raspberry PI, and finally we can send system-level notifications from the Raspberry to the phone (for both Android and iOS) without downloading any kind of application (this would be very important).
The project would be based on a Raspberry PI 5 and an nRF52840 Bluetooth 5.0 Evaluation Kit module.
My questions would be:
- can the project be solved with the listed elements?
- approximately at what distance could I maintain contact with these devices?
- can the module be configured so that it can establish a connection and send messages to Android and iOS systems at the same time (without an application), or is it worth using two separate modules due to the different protocols?
Thank you in advance for the answers,
Best regards,
Csaba Dajka
