  This is the code block with the issue:

  - (BFTask *)deactivateAsync

  {

      return [BFTask taskFromMetaWearWithBlock:^id{

          self.activateCount--;

          if (self.activateCount == 0) {

              activateTask = [[[self.module deactivateAsync] continueOnMetaWearWithSuccessBlock:^id _Nullable(BFTask * _Nonnull task) {

                  return [self performAsyncDeactivation];

              }] continueOnMetaWearWithBlock:^id _Nullable(BFTask * _Nonnull task) {

  I updated the firmware - and devices connect now  - weird. 

  Any ideas on why would this happen ?

  What is your app doing?  If the template app is still working, perhaps something in your app is not properly using the iOS SDK.

  
  

  Some other users have had similar issues before, perhaps those threads can provide some insight.

  FYI: I couldn't really find a reason for the error - checked that streaming  and notification events were being properly added and removed.. so I fixed it by adding a check here: 

  
  

  
  

  return [BFTask taskFromMetaWearWithBlock:^id{

  ***** if (self.activateCount > 0 ) { ********

          self.activateCount--;
