openL2CAPChannel fails on iOS - same code works on macOS

[denis]

Attached is a nRF52840-DK project and an Xcode project with iOS and macOS targets.  When I run on macOS the L2CAP channel is opened.  When I run on iOS the L2CAP is not opened.  Any ideas on why this might be?  Anyone know of iOS working with nRF5 L2CAP examples?

Hi Denis

I was just having the same problem as you because on iOS side, I was not keeping a strong reference to 

the CBL2CAPChannel object given by:

- (void)peripheral:(CBPeripheral *)peripheral didOpenL2CAPChannel:(CBL2CAPChannel *)channel error:(NSError *)error

Now I will try to send/receive data from it...
