Hi. We are experiencing connection issues using the IotDataManager mqtt API in the following circumstances

1. connect the app to IOT using iotDataManager.connect(...) when app in foreground - success publish/subscribe
2. issue disconnect after a while when app is in foreground
3. issue a connection after a while when the app is in background using iotDataManager.connect(...) i get the error:
   getIdentityRef error: -25308
   Could not find SecIdentityRef
4. issue a connection after a while when app is in background using iotDataManager.connectUsingWebSocket(...) - success publish/subscribe

AWS IOS SDK version: 2.21.0

I'm having exactly the same issue (AWS iOS SDK version : 2.27.6. I'd love to know if this issue was ever resolved (or a workaround identified)

I think it's somehow linked to needing to save the SecIdentityRef in the keychain using kSecAttrAccessible : kSecAttrAccessibleAfterFirstUnlock so that it's accessible from the background, but I can't work out where this needs to be added.

Searching around on the internet for similar issues from others, I also wonder whether this is relevant:

@gadget-man Our team is investigating the issue the will provide an update soon.

@harsh62 are you able to provide any update (or timescales) for this fix? Currently, Apple Watch apps that need to call the AWS iOS SDK on their paired phone in the background are unable to work.

We have a PR to add accessibility level to the IoT SDK - #4159 , We will let you know here when this is released, in the mean time you can try this dev branch royjit.keychain and test.
