Maybe the OBEX part is a little bit screwed up. However I can't say anything without comparing the setups of both connections. For the BlueSoleil connection you would need to make an air trace. For the BlueZ connection it is enough if you create a trace with "hcidump -X -V". Regards Marcel ------------------------------------------------------------------------- Take Surveys. Earn Cash.
