iOS CoreBluetooth reconnecting device with pair

[steven]

now,i pairing my peripheral and Communication read/write data. but have some issue for disconnect/reconnect .

1.disconnect: when i disconnect (call didDisconnectPeripheral) the iOS not disconnect my peripheral why that not disconnect ? how to disconnect ?

2.reconnect: other i turn off my peripheral , and re-connect (connectperipheral) but can't read/write how to solve " 2013-12-05 21:16:52.206 Alarm Clock 1.0[1542:60b] CoreBluetooth[WARNING] is not a valid characteristic for peripheral "

1. This seems to be a deliberate choice by iOS. With some previous iOS version, the delay was up to 1 minute, but later versions seems to disconnect quicker. If you need it to be faster, you can consider adding a characteristic on your Peripheral, and disconnect from the Peripheral side once the Central writes to it.

2. You can't store a CBCharacteristic between connections, so I'd recommend you to rediscover services and characteristics each time you get the didConnect callback. However, on a second connect, CBPeripheral:services and CBService:characteristics may already be filled, so you can also check these directly.

hi, i need explain question again,

same as this questio:TitleI OS Bluetooth LE : unable to connect using stored pairing data

i connect my device with pair and bond, and that is success work(read/write characteristics data)

when issue it is wrong : devices: 1.reset power , then re-Advertising (by BLE_GAP_ADV_TYPE_ADV_DIRECT_IND) when i do it ,my iOS will be auto connect my device ,event no App work. it it right? if it is right, how to get the peripheral service uuid and characteristic ?

iOS: 1.on my app, call "cancelPeripheralConnect:self.currentPeripheral.peripheral]; to disconnect with my device,but it will not action. (my device go to disconnect,only have i delete the Bluetooth pair information)

Is there someone with experience with Bluetooth LE and IOS to help me?

Hi,

iOS doesn't support directed advertising, therefore the problem may be related to the fact that you are using it (BLE_GAP_ADV_TYPE_ADV_DIRECT_IND).
