I am very new to Raspberry Pi and I am trying to make small device based on it (Raspberry Pi 3). In order to work properly this device need to be connected to the Internet, for example, over wi-fi.
The problem is that i want user to be able to configure internet connection for this device from his smartphone. What is most suitable way for doing this? I thought Bluetooth is the one of the possible options.
One way would be to pre-configure the RPi to connect to AP called e.g. AndroidAP with no password (or a known password), then instruct the user to activate such AP on their smartphone. This requires the smartphone to support connection sharing (which most modern devices do) and is not that great security-wise, but it's an option. Here's how to do it.
Bluetooth is also an option: it's possible to make the RPi discoverable and accept pairing requests without a PIN. Here's an example of such setup.
