POConnect to LightBlue peripheral mode
text
Body
copied!<p>I used LightBlue app on an IOS Devices (iPhone 4s, iOS 6.1.3) in peripheral mode and another IOS device (iPhone 4s, iOS 6.1.3) in a central mode.</p> <p>I'm using <a href="http://developer.apple.com/library/ios/#samplecode/BTLE_Transfer/Introduction/Intro.html" rel="nofollow">BTLE Transfer</a> example code from Apple, it's working properly on these two devices. However, It does not work on LightBlue. As I just want to develop a simple app that read data from Blood Pressure Device, I've just changed the following service and characteristic UUID in Transfer.h file</p> <h1>define TRANSFER_SERVICE_UUID @"1810"</h1> <h1>define TRANSFER_CHARACTERISTIC_UUID @"2A49" // just read value</h1> <p>My plan is going to clone a real device structure on LightBlue and then develop a central app to connect with LightBlue peripheral (I think it then will work with real devices because I donot have any real device at the moment). I set a device as a peripheral and the second one will install modified app (from apple sample) as a central or client.</p> <p>The following delegate method provided by Apple:</p> <pre><code>- (void)centralManager:(CBCentralManager *)central didDiscoverPeripheral:(CBPeripheral *)peripheral advertisementData:(NSDictionary *)advertisementData RSSI:(NSNumber *)RSSI { // Reject any where the value is above reasonable range if (RSSI.integerValue > -15) { return; } // Reject if the signal strength is too low to be close enough (Close is around -22dB) if (RSSI.integerValue < -35) { return; } NSLog(@"Discovered %@ at %@", peripheral.name, RSSI); // Ok, it's in range - have we already seen it? if (self.discoveredPeripheral != peripheral) { // Save a local copy of the peripheral, so CoreBluetooth doesn't get rid of it self.discoveredPeripheral = peripheral; // And connect NSLog(@"Connecting to peripheral %@", peripheral); [self.centralManager connectPeripheral:peripheral options:nil]; self.connectingPeripheral=peripheral; // this line of code I have added as recommended from a member } } </code></pre> <p>And the problem is, this delegate method have been fired and log panel display "Discovered LightBlue at -32".It likely cannot connect to the Lightblue peripheral as I cannot see the output of the line of code NSLog(@"Connecting to peripheral %@", peripheral);</p> <p>All suggestion are welcome and highly appreciated. </p>
