ios mobile stop reconnect to hid keyboard

[William.wei]

hi support team,

for our sdk17.0.2 demo hid_keyboard, i tested it and using IOS mobile to pair with our 840dk or 832dk

find out after  lots of reset the keyboard device（52840dk pinreset）, IOS mobile stop reconnect to our 840DK, I have to click the keyboard device under bluetooth（ios mobile system）, only after this action, IOS will connect to our device.

so the question for this is, I think this IOS problem not ours, can we provide any explanation for customer? or any suggestions or solution to solve this problem?

Hi William,

It is quite some time ago, but maybe you are able to find some answers from the discussion and links in  Trouble with background reconnection after reset (iOS) ?

In addition to this, it could be helpful to see a Sniffer trace from when the error happens. It may give more insight into the issue.

hi Sigurd,

i don't use any app from background or foreground, i just use Bluetooth from mobile--->settings--->Bluetooth.

and this ticket is not much help on this.

and i sniffed keyboard, broadcasting is still there, just IOS is no reaction even i reset my device.

i can find basically the same question from developer.Apple.com:https://developer.apple.com/forums/thread/695730

but unfortunately, there is no reply to this question.

by the way, we can reproduce this problem, just continue quickly pressing reset button on our DK based on our ble_hid_keyboard demo.

just reset DK as quick as possible when IOS is try to reconnect to it as below.

Regards,

William.

I agree that it sounds like a iOS issue in this case.

Unfortunately, I am not able to give any advise on how to fix this on the iOS side.
But our iOS experts are back from vacation next week.
I will assign the case to one of them, and then maybe they will be able to assist you more at that point.

Thank you Sigurd,

Looking forward to some advice from our experts.

Hello William,

iOS stops "auto" connecting if there are too many reconnects being made in a short amount of time. Exactly what counts as too many is not documented as far as I know, but based previous on testing it seems like you need to have several reconnects within 10 seconds for this to happen. They can try to make the peripheral request a longer supervision timeout (e.g. 5 seconds) to avoid the problem.

Regards,

Vidar

Thanks Vidar，

for your suggestion, longer supervision timeout should be work for those that signal is week like this ticket in apple community:https://developer.apple.com/forums/thread/695730

but for our customer testing, they continuously press the reset button( device reset ）, still can cause IOS stop auto connection, looks like there is no solution to this, am i correct? 

(for now , I searched all the dev zone and google, there is no answer to this solution）.

Regards,

William.

It won't help if the device is reset before the longer supervision timeout has been accepted by the phone.
