[BT] Client and Server - Am I Right ??

Hi all !!
I´m just beginning with BlueTooth programming for Symbian OS C++ and I´d like to see, wether I´m clear or not ... It´s possible to act as a Server (like example BTAdvertiser) or as a client (like BTDiscoverer). I want to send a message ... I don´t care about security ... yet ...  As a Client : - You check for devices => You get a BT Address - You search for services => You get the ports of remote services (for instance: the port number to work with Serial Profile) - You can now connect to SocketServer using Address and Port found (for instance all this with RFCOMM) - You write your socket (basical ! I could also wait and read the socket for incoming messages ... but I just want to send one) - You close your socket. As a Server: - You check BT is on - You load drivers - You allocate a port for your service (for instance for Serial) - You register your service to SDP (so that other devices could find it) - You connect to SocketServer - You start listening, reading and writing data ... Is this right ? My Problem: I have to work with devices, which have no SDP. I think, the only difference is that I DO have to know the port number and I may directly connect to SocketServer with this information ... I would be really gratefull if someone could tell me I´m right or where I´m wrong because I don´t want to start coding without knowing the basical scheme ! Thanx thanx thanx !!!! Valentin |

I currently working on a project involving the use of communicating between two devices over BT. I work with P800 phones. It is possible to work both as a server and a client as you mentioned.
As long as your client knows the port number of the service, you can connect directly without using the SDP.
