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)

Hi all,
Since im new to bluetooth low energy technology , i need some guidance from
you . Following are the issues that im searching for a solution
1 : Is it possible to establish mutiple LE connection at a time . Im using
fedora 13 , linux 2.6.39 version with 4.0 LE supported dongles
2: now im not concentrating on user profiles like GATT and ATT . i wanted to
do it using HCI and L2cap connections
You are able to establish one LE connection at a time. If you have
more than one device you want to connect to, you can use whitelist.
Add the devices to whitelist and issue the LE connection command. As
soon as one of the devices starts advertising, the connection will be
established.
You can use hcitool to add devices to whitelist and issue LE connection command.
BR,
Andre
