nrf Mesh Android Application crashing issue

[BryceCDI]

Good Afternoon,

Im using a samsung galaxy tab a - Model num SM-T510

Android Version 10

nRF Mesh app version - 3.1.5

After provisioning 14 nodes, whenever i try to reset one, the app crashes. 13 nodes work absolutely fine, for some reason the issue arises whenever a 14th node is provisioned.

Notes - The reset mesh message is sent and received by the node, a couple of times the node will not be removed from the list of nodes, but the physical node will return to pre-provisioned state. 
"ConcurrentModificationException" is the exception that is being thrown.

An explanation on this behavior, as well as a fix would be much appreciated.

Best Regards,
Bryce

Hi Bryce, 
I have forwarded your question to our R&D team. They will have a look into the issue. I will keep you updated.

The application was trying to access the list of nodes on one thread while trying to remove the node that has been reset on another thread. The issue has been fixed for my application however, the issue still persists on the base application.

Thanks Bryce for the update. I think you found the bug. I have reported this back to the developer. We will try to get a fix out on the next release.
