Hello word from Arduino to iPhone

Projects General Guidance

Hi
What I can use to send from Arduino to iPhone - Hello world

2

Bluetooth

3

I know that I can use Bluetooth or Wi-Fi but I don't know which

4

Trying both?

5

I know that I can use Bluetooth or Wi - Fi but I don't know which device to pick up

6

do iPhones support Bluetooth classic?
you could certainly use BLE
you could use MIT app inventor to implement an app for the iPhone

7

I don't understand the question

Let's start from the beginning
Which Arduino board are you using ?

8

Uno

9

maybe HC-06 ?

10

No.
IOS is incompatible with Bluetooth Classic like HC-0x.
You need a BLE device.

Only you can make the choice about which device to pick up, but if your ambitions go no further than saying hello world, you might as well use Bluetooth. It is a lot simpler.

11

HC-06 only supports Bluetooth 2.0 Classic
if your target requires BLE consder the HM-10 and even a ESP32 which has builtin WiFi, Bluetooth Classic and BLE which would give you much more flexibility
