Raspberry Pi Bluetooth 4.0 Connection

问题:

I am trying to connect to a Raspberry Pi via iPhone using CoreBluetooth (bluetooth 4.0). I have discovered the device and send out a connection request using this code:

if (peripheral != self.foundPeripheral) {
    NSLog(@"Try to connect to %@", peripheral.name);
    self.foundPeripheral = peripheral;
    [self.centralManager stopScan];
    [self.centralManager connectPeripheral:peripheral options:nil];

}

Neither the didConnectPeripheral or didFailedToConnectPeripheral are called. I also made sure to set the RPi to advertise bluetooth low energy using

sudo hciconfig hci0 leadv

but when I check active connections with

hcitool con

there are no active connections. Am I missing some set up for the RPi? Also the name variable on the peripheral is blank, is that because I have not connected yet?

Try out bleno, it's a node.js library that can be used to create a BLE peripheral on both OS X and Linux. It works well on my Raspberry Pi running Raspbian.
