I would suggest you issue a disconnectPeripheral: call to cancel the pending connection request when your timer fires, and then listen for the didDisconnect callback to ensure that the connection request was canceled. As Dylan mentioned, connection requests remain ‘out there’ until a connection is made or until you get a didFailToConnect delegate callback (I have yet to encounter this didFail delegate method).

Hope this helps.

Best regards,

Steve Jaynes

Subject: Re: Multiple callbacks to didConnectPeripheral for the same peripheral device

Connect peripheral really only needs to be called once. It remembers what you have asked and will call you back. In your case the connection may be starting to come up while you are asking for another callback and so you get multiple or maybe CB is now doing 1:1 callbacks.

I've given up expecting a predictable series of events and now are very defensive in handling callbacks.

I call connectPeripheral and set a timer. When the didConnectPeripheral delegate callback is made, the first thing it does is invalidate the timer. If instead the timer fires, the app will re-attempt the connection up to three times. I expected that the subsequent connectPeripheral calls to CB to connect to a given peripheral would override the previous request, and that's how it used to appear to work. Recently I've noticed that sometimes, after re-issuing the connect request, I'll get a second didConnectPeripheral callback for the same peripheral. This leaves me with the task of filtering out and ignoring the extraneous callbacks. Or not knowing whether I now have two connections open and must formally disconnect all but one?
