I'm currently working on an IoT project. The principle is to have a box that could connect to a phone over Bluetooth on some NFC contact. After the phone and the box will communicate messages over Bluetooth to the phone.
The box must be able to pair with the phone and when an NFC contact is triggered send a message to the phone using Bluetooth.
I've started by developing a truly basic prototype of it using a raspberry pi and an NFC PN532. I now want to develop a new version of it using some dedicated hardware, the idea is to get as near as possible of an industrial version.
I've seen two different hardware to do so:
the first one is a Toshiba micro-controller (https://toshiba.semicon-storage.com/eu/product/wireless-communication/bluetooth/TC35670.html) and
My problem is that as I have no experience at all in IoT and I am more of a software engineer than hardware engineer I don't really know which one is the better for my project.
I then have two questions:
Do you know any other hardware piece that allows Bluetooth and NFC ?
Which one would you advise for me ? How can I truly differentiate them ?
Thx for reading me.
PS: please pardon my English I'm still learning ;)
