pebbleCentral:watchDidConnect never gets called on iOS - ios

Question

I have an old Pebble Classic watch, upgraded to latest firmware (3.8.2) and using latest Pebble-SDK.
I have followed the few simple steps to install SDK, setup an Xcode project and adding the code to initialise and connect:
https://developer.getpebble.com/guides/mobile-apps/ios/
My problem is, that the delegate method pebbleCentral:watchDidConnect never gets called!
I am using the Pebble Time app on the iPad to install the watchApp in the watch, so I know the iPad is connected to the watch. The same iPad runs the iOS app, which apparently does not discover the watch.
I have tried to import an old test project from a colleague, who had it running a year or two ago. Same watch, same watchApp, but of course older firmware and SDK versions. Same result...
I think the documentation on the pebble site is quite simple and easy to follow. However, I feel I am missing some explanations of how and when this watchDidConnect is supposed to be triggered.
I am most likely missing some simple step somewhere, but I am quite lost in where to look!
Any ideas are welcome!
EDIT: My code looks like this:
ViewController.h:
#import <UIKit/UIKit.h>
#import PebbleKit;
#interface ViewController : UIViewController<PBPebbleCentralDelegate>
#end
ViewController.m:
#import "ViewController.h"
#interface ViewController ()
#property (weak, nonatomic) PBWatch* connectedWatch;
#end
#implementation ViewController
- (void)viewDidLoad {
[super viewDidLoad];
[PBPebbleCentral defaultCentral].delegate = self;
[[PBPebbleCentral defaultCentral] run];
NSLog(#"Pebble initialised");
}
- (void)didReceiveMemoryWarning {
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
- (void)pebbleCentral:(PBPebbleCentral*)central watchDidConnect (PBWatch*)watch isNew:(BOOL)isNew {
NSLog(#"Pebble connected: %#", [watch name]);
self.connectedWatch = watch;
}
- (void)pebbleCentral:(PBPebbleCentral*)central watchDidDisconnect:(PBWatch*)watch {
NSLog(#"Pebble disconnected: %#", [watch name]);
if ([watch isEqual:self.connectedWatch]) {
self.connectedWatch = nil;
}
}
#end

Are you calling the -run method, after setting up your Pebble central? I noticed that the code snippet in the link you posted does not show the central's delegate being set.
[PBPebbleCentral defaultCentral].delegate = self; // Set your delegate
[PBPebbleCentral defaultCentral].appUUID = [[NSUUID alloc] initWithUUIDString:#"Your Pebble App UUID"]; // Set the app UUID
[[PBPebbleCentral defaultCentral] run]; // Call -run on the central
