Immediate Disconnect in iOS6

Other Parts Discussed in Thread: CC2540

Hello,

It seems that in iOS6 the connection disconnect command does not get issued immediately (the delay is in the 45 seconds range). In our application, we'd like to disconnect and reconnect again within a few seconds

Is there a workaround to immediately terminate the connection without going through the iOS commands ? Would it be possible to use the HCI_EXT_DisconnectImmedCmd API to terminate the connection ? If so, would the module go back to advertising upon disconnection ?

Thank you.

if the device on the other end of the connection is under your control (and a cc2540) you could simply issue GAPRole_TerminateConnection(); on a write to a dedicated characteristics and when the state changes to GAPROLE_WAITING restart the advertising.

Hi Andre,

Thank you for the quick reply. Yes I am using the CC2540. If I already have an advertisement interval established by default (at initialization), wouldn't it go back to advertising automatically after transitioning from the GAPROLE_WAITING state ?

i'm not sure. I guess this depends on the exact setup of your ADV-configuration.

You could simply test that, though :)
