Re: BLE - multiple connections

[Ajay KV <ajay.kv@globaledgesoft.com>]

  Hi ,
         I am facing some more issues regarding BLE multiple connection 
, which is mentioned below . please  show me the right direction , since 
i got stucked

1:  suppose device A  and B is in connected state (B as initiator  and 
A  as advertising mode)  , so obviously role change happens and A 
switches to slave mode .  meanwhile i wanted to  connect device C  to A 
(C as initiator  and A as advertising mode) , since  A has switched to 
slave mode , it cant able to advertise again ( controller returns  error 
message " command disallowed") .  Even i tried to change the role  
forcefully through hcitool command ,  the result was same.
          My intention is to make  the device A as a server with 
multiple clients.  Currently im not using any of the profiles(ATT , 
GATT) . i want  it to be done using L2CAP sockets

2. Is it possible to change the imtu  of the LE connection other than 
23bits( which is hardcoded in L2cap driver)
