Hello, I am currently developing a BLE application which advertising customer specific data with the company identifier 0x024D. The advertising packet only consists of the flags and the mentioned manufacturer specific data. I’ve noticed that the latest version of OS X sends a scan request to these devices which I answer with an empty response. Afterwards it will connect to my devices and will write some data to them. I do not answer this data and OS X stays connected to this device for a very long time. I haven’t noticed any disconnect yet. Is this a new behaviour introduced in the latest version of the OS? If yes, I think that this behaviour should be reconsidered because I think that only advertsiing packets of interest should be ansered and not every device should be connected. Otherwise, this will lead to serious troubles. Here’s a screenshot from my sniffer: https://devzone.nordicsemi.com/attachment/73bb4ecb00aa40c4c7ecdd608b9660a0 Marius Gesendet von Mail für Windows 10 |
