Disconnecting ACL links

How to disconnect ACL links

The TLMDisconnectACLIoctl structure contains the device address of the remote device to be disconnected and the reason code to be supplied during the disconnection.

Basic Procedure

To directly disconnect individual Bluetooth ACL links:

1. Create a TLMDisconnectACLBuf packaged structure, which contains the address of the Bluetooth device to be disconnected and the reason to be given to the other device for its disconnection.

2. Call the KLMDisconnectACLIoctl ioctl on the socket with the link manager level KSolBtLM , passing the package buffer.

Example: Disconnecting ACL links

Here is a simple disconnect example.

1. Starting with an open socket

            
             
            
            RSocket sock;
   ret=sock.Open(ss,pInfo.iAddrFamily,pInfo.iSockType,pInfo.iProtocol);
           

2. Identify the Bluetooth device to be disconnected and provide a reason for the disconnect.

            
             
            
            TLMDisconnectACLBuf aclConnBuf;
   aclConnBuf().iDevAddr = devAddr; // devAddr is a TBTDevAddr
   aclConnBuf().iReason = 0x13; // Remote User Ended Connection
   TRequestStatus stat;
           

3. Send Ioctl command to disconnect.

            
             
            
            sock.Ioctl(KLMDisconnectACLIoctl, stat,  &aclConnBuf, KSolBtLM);
   User::WaitForRequest(stat);
