Thanks all, finally it works. But it still has the issue that: snd_pcm_hw_params() give the return value "1". In BlueZ stack. File: audio/pcm_bluetooth.c Function: bluetooth_prepare() If I hard code the return value to 0, it will be ok. The function call write(data->pipefd[1], &c, 1) gives a positive return value cause the issue. >-----Original Message----- >From: bluez-devel-bounces@xxxxxxxxxxxxxxxxxxxxx >[mailto:bluez-devel-bounces@xxxxxxxxxxxxxxxxxxxxx] On Behalf Of Zhao, >Halley >Sent: 2008年5月13日 10:22 >To: BlueZ development >Subject: Re: I can't use 3.31 release,but 3.19 release works >on the same platform > > My hcid is in /usr/local/lib/Bluetooth/plugins > It is surprise, I will redo "configure ...., make && make install" to >have a double check. > > hcid[32647]: Loading plugins /usr/local/lib/bluetooth/plugins > > > >-----Original Message----- > >From: bluez-devel-bounces@xxxxxxxxxxxxxxxxxxxxx > >[mailto:bluez-devel-bounces@xxxxxxxxxxxxxxxxxxxxx] On Behalf Of >Zhao, > >Halley > >Sent: 2008年5月13日 9:00 > >To: BlueZ development > >Subject: Re: I can't use 3.31 release,but 3.19 release >works > >on the same platform > > > > Great thanks.
