Trouble with background reconnection after reset (iOS)

Hi Andy,

We had the same issue with during the development of our paid parking lot automation solution (gate barrier managing device + apps + backend).

First of all: It is necessary to properly adjust the adverting intervals on the side of the BLE device.

FYI: iOS does not cache any scan intervals. The already run app has much shorter intervals than it has in the background mode.

Let me know if there are any other questions.

Thanks,
Ilya.

Unfortunately I'm not in charge of the mobile app development so I can't really say how the background reconnection is made. I'm just wondering if I can make life easier for the app development team somehow.

I will ask and see if I can get some code from the iOS app here.

I talked to one of our developers and he don’t think it is a phased out scanning issue, to guarantee that you can try advertising fast, then slowing down over time and see how things work.

How do you reconnect in the background? Is it possible to upload some code?

So it looks like there isn't much to do from the NRF52 side, and most of the work needs to be done on the iOS side. Besides adjusting GAP connection parameters, I didn't really see anything to be done.
