Apple

The iOS device is only "discoverable" while you are in the Bluetooth settings screen. However, it is always "connectable". Meaning, if you know the Bluetooth Device Address (BD_ADDR) of the iOS device you can create a connection to it from the accessory. Please note that the iOS device will only allow the incoming connection if it comes from an already paired device. That is why it is necessary to first pair with the accessory from the iOS device, which you also do in the Bluetooth settings screen.

Hi Linde,

    Thanks for your reply, what you talk is just what we need.

    Could you explain more particular on how to initial the connection from the accessory.

    It can be worked when we initial the connection in settings screen. But when we try to initial the connection from accessory, we can not find the iOS device even we have paired before.

Best regards!

Subject: Re: Q: Connect to iOS device with Bluetooth

Hi Cong Ming,

There are two ways to connect a Bluetooth accessory to an iOS product. First, you can pair and connect from the Bluetooth settings screen (Settings->General->Bluetooth). From this screen you can do the initial pairing. After the accessory has been paired with the iOS device, you can then connect to the device from this screen. The second way is to initiate the connection from the accessory. The accessory has to first be paired with the iOS device for the iOS device to allow the incoming connection from the accessory.

Hope this helps. Let me know if you have any further questions.

Regards,
Joakim

Hello everyone,

    Does there any method to make the accessories connect to iOS device more easily or automatically for the end user? For save their opeartion.

    In case that, the accessory had already paired with iOS device, and can be found in the BT device list.

    And when both side BT is opened, could the accessory establish the connection initiative (means as the master)?

    Or another way, could the apps replace the Setting Menu, control the switch of the BT, and start connect to appointed accessory?

   I'm not sure whether my question is submission to the correct position. And if it not, please notify.

   Wish your help.
