pebble sdk - pebbleCentral:watchDidConnect never gets called on iOS -

i have old pebble classic watch, upgraded latest firmware (3.8.2) , using latest pebble-sdk.

i have followed few simple steps install sdk, setup xcode project , adding code initialise , connect: https://developer.getpebble.com/guides/mobile-apps/ios/

my problem is, delegate method pebblecentral:watchdidconnect never gets called!

i using pebble time app on ipad install watchapp in watch, know ipad connected watch. same ipad runs ios app, apparently not discover watch.

i have tried import old test project colleague, had running year or 2 ago. same watch, same watchapp, of course older firmware , sdk versions. same result...

i think documentation on pebble site quite simple , easy follow. however, feel missing explanations of how , when watchdidconnect supposed triggered.

i missing simple step somewhere, quite lost in look!

any ideas welcome!

edit: code looks 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 resources can 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 calling -run method, after setting pebble central? noticed code snippet in link posted not show central's delegate being set.

[pbpebblecentral defaultcentral].delegate = self; // set delegate

[pbpebblecentral defaultcentral].appuuid = [[nsuuid alloc] initwithuuidstring:@"your pebble app uuid"]; // set app uuid

[[pbpebblecentral defaultcentral] run]; // call -run on central
