the following code retrieves my peripherals and allows connection in old verisons of IOS. Since Ios13 this method no longer works.. Specifically.
NSArray* knownPeripherals = [self.centralManager retrievePeripheralsWithIdentifiers:@[uuid]];
this does not find results, however under the same test scenrio it works on older devices . Below is the entire method. any ideas on why i can not get my peripheral would help.
self.discoveredPeripheralMap = [NSMutableDictionary new];
self.connectingPeripherals = [NSMutableArray new];
NSDictionary* centralOptions = @{ CBCentralManagerOptionRestoreIdentifierKey: CentralManagerIdentifier };
self.centralManager = [[CBCentralManager alloc] initWithDelegate:self
queue:nil
options:centralOptions];
NSUserDefaults* defaults = [NSUserDefaults standardUserDefaults];
NSString* savedDeviceId = [defaults objectForKey:SavedBluetoothDeviceIdentifierKey];
if(savedDeviceId)
{
NSUUID *uuid = [[NSUUID alloc] initWithUUIDString:savedDeviceId];
//NSUUID* uuid = [NSUUID UUIDWithString:savedDeviceId];
NSArray* knownPeripherals = [self.centralManager retrievePeripheralsWithIdentifiers:@[uuid]];
if(knownPeripherals && knownPeripherals.count > 0)
{
CBPeripheral* peripheral = knownPeripherals[0];
_defaultPeripheral = [[DVBPeripheral alloc] initWithPeripheral:peripheral];
[self.discoveredPeripheralMap setObject:self.defaultPeripheral forKey:peripheral.name];
if(self.centralManager.state == CBCentralManagerStatePoweredOn)
{
[self connect:self.defaultPeripheral];
}
}
}
}
