basically i have two apps, one for scanning for bluetooth devices and the other for advertising, and what i am trying to do is to get a list of all iOS devices, within my proximity on the app which scans for the iOS device .
This is my code so far:
Scanning.m:
// Scan for all available CoreBluetooth LE devices
NSDictionary *scanOptions = @{CBCentralManagerScanOptionAllowDuplicatesKey:@(YES)};
NSArray *services = @[[CBUUID UUIDWithString:@"1CC024D6-E413-4B56-993C-831CAF033366"]];
[self.centralManager scanForPeripheralsWithServices:services options:scanOptions];
- (void)centralManager:(CBCentralManager *)central didDiscoverPeripheral:(CBPeripheral *)peripheral advertisementData:(NSDictionary *)advertisementData RSSI:(NSNumber *)RSSI
{
NSLog(@"RSSI: %d", [RSSI intValue]);
}
// method called whenever the device state changes.
- (void)centralManagerDidUpdateState:(CBCentralManager *)central
{
// Determine the state of the peripheral
if ([central state] == CBCentralManagerStatePoweredOff) {
NSLog(@"CoreBluetooth BLE hardware is powered off");
}
else if ([central state] == CBCentralManagerStatePoweredOn) {
NSLog(@"CoreBluetooth BLE hardware is powered on and ready");
}
else if ([central state] == CBCentralManagerStateUnauthorized) {
NSLog(@"CoreBluetooth BLE state is unauthorized");
}
else if ([central state] == CBCentralManagerStateUnknown) {
NSLog(@"CoreBluetooth BLE state is unknown");
}
else if ([central state] == CBCentralManagerStateUnsupported) {
NSLog(@"CoreBluetooth BLE hardware is unsupported on this platform");
}
}
Advertising.m:
self.peripheralManager = [[CBPeripheralManager alloc] initWithDelegate:self queue:nil];
[self listenForRelays];
/** Required protocol method. A full app should take care of all the possible states,
* but we're just waiting for to know when the CBPeripheralManager is ready
*/
- (void)peripheralManagerDidUpdateState:(CBPeripheralManager *)peripheral
{
if (peripheral.state == CBPeripheralManagerStatePoweredOn)
{
// We're in CBPeripheralManagerStatePoweredOn state...
NSLog(@"self.peripheralManager powered on.");
// ... so build our service.
}
}
-(void) listenForRelays {
if(self.peripheralManager.state == CBPeripheralManagerStatePoweredOn)
{
NSDictionary *advertisingData = @{CBAdvertisementDataLocalNameKey:@"my-peripheral",
CBAdvertisementDataServiceUUIDsKey:@[[CBUUID UUIDWithString:@"1CC024D6-E413-4B56-993C-831CAF033322"]]};
// Start advertising over BLE
[self.peripheralManager startAdvertising:advertisingData];
}
}
When i run the different apps on different iphones, nothing happens !
This doesn't crash but didDiscoverPeripheral never gets called :( please help me out ! and yes i have gone through the documentation but still no good :((
cheers
