CBConcretePeripheral Warning "not a valid peripheral"
by Alexey Grechaninov 24 May '13

Hello everyone! I'm getting very strange things. Periodically my CBPeripheral becomes invalid and I have no idea what does is mean. Connection passes fine, then I retaining CBPeripheral instance and everything works fine until suddenly the peripheral become "invalid". When is happens - it still indicated as connected and .isConnected returns true. The only solution is to restart the app. Here is example how it looks: May 24 21:49:17 iPhone-5-Alexey BB Utility[4464] <Warning>: CoreBluetooth[WARNING] <CBConcretePeripheral: 0x200956a0 UUID = <CFUUID 0x2008b600> B17DDC76-54FA-080A-E029-C5421813C45C, Name = "Device Name", IsConnected = YES> is not a valid peripheral "– centralManager:didDisconnectPeripheral:error:" never gets called as well... Is just hangs and fills the console with provided warning message. Looks like bug in iOS. Did anyone faced this issue?

Self-connect possible?
by Albrecht Haug 24 May '13

There are no stupid questions, right? So: can the very same iOS device be peripheral and central at the same time? Or more specific: can the peripheral server connect to a central client that is listening on the same device? If yes: is there a code example? If not: why? –Albrecht _______________________________________________ Do not post admin requests to the list. They will be ignored.

Or another example is if when you're presented the pairing dialog box you hit 'cancel' or type a wrong pin it will return this error code. What do you mean by the peripheral being in the background? In this case, there's no pin. It does present the pairing dialog, to which you say pair or cancel, but that has always worked in the past. Now I don't know how to reset it. I eventually just changed my peripheral to not require auth for certain characteristics. -- Rick _______________________________________________ Do not post admin requests to the list.

UserInfo=0x1f0df1f0 {NSLocalizedDescription=Unknown error.} A little Googling turned up that this is an insufficient authentication error. Never saw this before, but we do have a series of Characteristics with authenticated_read and or _write set to true. For the moment, we've simply set those to false. Can't seem to get around the problem otherwise. -- Rick _______________________________________________ Do not post admin requests to the list. They will be ignored.

Can you explicitly read a subscribed Characteristic value?
by Rick Mann 23 May '13

23 May '13

This SO answer suggests you cannot: http://stackoverflow.com/questions/14482155/corebluetoothwarning-unknown-er… But I need to do that. I don't get the value notification just for subscribing, as far as I can tell. Maybe I'm wrong, since I subscribe and then immediately issue a read. -- Rick _______________________________________________ Do not post admin requests to the list. They will be ignored.
