 Okay today, we are looking into Bluetooth connection via NFC The good old days when you have a Bluetooth device You would basically Have this scan for its present for example Imagine that this device is lost in a multitude of MAC address That is visible within the view of the phone and Therefore to identify it unless you have to know its name and if the name is Duplicated it can be quite a pain to to see which one you're looking at so What NFC does is that it? Simplify and make it easy for us Here I have the STM32WB microcontroller with integrated Bluetooth Controllers on board and I also have the X nuclear NFC 04A1 and this this device is Is a NFC dynamic tag? It consists of a NFC type 5 tag IC You can connect it via an antenna so you can talk to it VRF On the other hand it has an I2C bus you can talk to the microcontroller down below the WB55 so on this Application we store an end-app message that contained That contains the MAC address and the Bluetooth name So that every time we tap on the NFC we can get that information Then we can connect easily using the app Show you quickly that process going to run a simple app and I will tap the antenna So as you can see I quickly connect to this device and it is a heart rate monitor It actually stopped monitoring my heart at all. It's actually generating a Kind of a simulated beep a minute and it's being So every time I connect it connect to it I can get that heart rate and although the heart rate is simulated it just want to show you that there is Bluetooth communication between this board and the phone so as you can see NFC has greatly simplified the ability to connect to a wireless devices is Bluetooth Capable devices like this one And you can do it with a single tab to connect. Thank you
