When two Bluetooth devices are within range of one another, they don't trust each other; at least not nonetheless. For them to get along, you need to put i or both of them into pairing way. Once washed, the two devices look for other gadgets that are accepting new pairings.

When the two devices find one another, they sometimes present you lot with a challenge to ensure you're connecting upward the right gadgets. For instance, if you connect upwardly to two Bluetooth devices with a screen, they may both evidence the same four-digit code and enquire for your confirmation that they've connected properly.

Once the pairing process is complete, the two devices will trust one another and automatically connect when they're both turned on and in range. This continues until one device "forgets" the other, which you can frequently force a device to do through its settings.
