Braille display connection issues

Hello all, I am helping somebody learn how to use their iPhone via Skype. He has been able to connect his braille display to his iPhone 5 until recently. Now it will not connect at all. I have instructed him to reset both his braille display and iPhone yet it still won't connect. He says the iPhone recognizes the braille display but the display will not connect. Do you think this is a braille display issue or an iPhone issue? Thanks in advance for any help. Best regards, Jesse tregarthen

#1 Braille Display Connecting

Hello,
What model of iPhone and what iOS version?
What model of Braille display?

My experience is the most likely cause is the pairing code is being entered incorrectly.
With an iPhone 5s and iOS 7 there is often a limited opportunity to do this. If a pairing code is entered wrongly, sometimes iOS 7 will allow for another attempt. Sometimes after one wrong attempt, and for me almost always after two attempts, the iPhone will stop "seeing" the display and will not list it as an option. And then one must turn off the display, and power off the iPhone, meaning reboot. And then try again.
Keep in mind Braille displays are added under the Accessibility > VoiceOver > Braille Display settings, not under the Bluetooth settings.

#2 Thank you

Hello, thank you for getting back to me. It is an iPhone five and the braille display is a Braille Sense U2 mini made by HIMS incorporated. It is actually a braille note taker that can be used as a braille display. From what I understand, the iPhone recognizes the braille sense but it doesn't go much further than that. He can't even get to the point where it asks for a pin code. The braille sense does not even prompt him to put a pin code in. Thanks again, Jesse
