This is ok now, after some manipulations, trials and errors with broadcom-, anycomwidcomm- and microsoft bluetooth's and b.t. drivers it's working again.
In c.p. I have like before 1 post bluetooth-radio's (microsoft bluetooth enumerator + silicon wave wireless bluetooth adapter) and under network-adapters I have again 2 b.t. items also (b.t. pan #2 + b.t. rfcomm tdi #2) and the drivers are silicon wave wireless adapter 6.1.6002.18457 and sst boxone dongle 22.214.171.124 also may be important, are installed successfully. The b.t. wizard for sending files to the smartphone works fine, receiving does not work yet, but this is a fault probably in the smartphone itself (samsung star s5230) that for some reason still sees an old computername (no more in use after windows reinstall), this is visible with search directly from the smartphone, but is does receive files. Ok, solved for the pc part at least.
