Git/Installer Release Version:
Seen on SDK 5.20.00.52 and 5.40.00.40
 
Application:
multi_role
 
Problem Reproducibility:
Intermittent, 100% of time after some hours
 
Problem Description:
The project may get stuck processing inside llProcessSlaveControlProcedures.
 
Initial debug efforts indicate the device is trying to process a LL_ENC_REQ inside llProcessSlaveControlProcedures, which is an invalid combination. The connPtr seems to be incorrectly pointing to the master connection.
 
 
Steps to re-create the problem:
At this point, I have not been able to reproduce this issue on my end after some attempts simply connecting/disconnecting devices to/from multi_role.

The issue could be reproduce by the HCI Test application:

• Start legacy advertising on peer1
• DUT create master connection with peer1 while connection interval is max (4 sec).
• DUT start legacy advertising
• DUT start encryption procedure with peer1 by sending the following:
  Send_HCI_LE_Start_Encryption 0x0000, , ,
  Wait_HCI_Command_Status_Event 5000*TimingMultiplier, &encReq, Any, 0x2019
• Peer2 create master connection with DUT while connection interval is max (4 sec).

 Problem Resolution:
Update the current connection pointer inside the Link Layer when a new peripheral connection is established.
