Dear xen, it seems as if you do not know what exactly you want to achieve in your project, neither have the technical background to describe that. If you want to have a kind of Messenger app between two PDAs, or something like a VoiceOverIP-speech solution, then the easiest would be to take the software that is already available, install it and use it. I will give you a scenario, to outline what is involved in having two PDAs with a SIP (VoIP) client contact each other: Each PDA runs the VoIP software (there are few, but look for MS Portrait or SJphone). That software communicates over IP based networks, so the PDA will connect to a kind of "access point" via bluetooth to get IP connectivity. There are two common ways of doing this: Either via the proper BNEP (bluetooth networking, emulates an ethernet connection over which IP packets can travel) or DUN (dialup networking, emulates a serial modem, running PPP over bluetooth). Windows CE seems to only support the latter, so you will need an "access point" for your PDA. The SIP phone software registers with a SIP server (for example, asterisk). Note this is not strictly necessary, but once setup makes scaling up to multiple devices easy, and it cares for all those NAT/routing/dynamic IP problems that you would run into when trying to communicate directly between two sip phones behind a firewall. The most complicated part (besides setting up asterisk, but there are howtos that explain it quite well, and prepackaged DEBs) is to get your Linux box act as a DUN access point. This does not require any low-level bluetooth programming, or no programming at all. Just get your Linux box setup as a DUN server. No, I cannot help at that detail because I tried and did not manage: My PDA's windows CE plainly refuses to do any networking over Bluetooth. Generally that seems to be possible though, I have seen howtos that would just not work on my PDA. Try those, ask google. If you have precise questions, then ask. Try to give as much details of what exactly you try and what does not work, as possible and reasonable.
