Bonding and white listing iOS devices with CC2541 peripheral

Other Parts Discussed in Thread: CC2541

Hi All,

For iOS devices, once bonded with peripheral, can I use white list? Currently, this doesn't seem to be working. Even within 15 minutes.

I have bonded the CC2541 peripheral with iOS device. If I set GAPROLE_ADV_FILTER_POLICY to GAP_FILTER_POLICY_ALL, then connection and authenticated read works fine. But if I set it to GAP_FILTER_POLICY_WHITE, then the device can detect the advertisement but connection won't happen.

I am trying to figure out what is happening using packet sniffer. I will add more info soon.

Hello Tejas,

iOS devices uses private resolvable addresses that changes each 15 minutes. Therefore whitelisting iOS devices doesn't work.

Hi Eirik,

Thanks for your reply.

I read somewhere that after bonding, it is possible to white list the devices that are bonded in peripheral. If this is not possible, do I need to implement white list in application layer?

Another strange thing is that the bonded device cannot reconnect after white listing even within 15 minutes. However, it receives the advertisement even after white list is enabled.

Regards,

Tejas J

Hello Tejas,

For our stack with the CC2541 it is not currently possible I am afraid. You will have to add a similar functionality in the application layer to check on address after connection.

The whitelist is no longer supported by iOS and Android 5.0 (Lollipop). Reference this thread: e2e.ti.com/.../1428335
