I want to use Bluez because already have some programs developed using this API, but Freescale is using CSR soft stack on this board. I am using bluez-lib and bluez-utils 3.26. I think it is some error in my PSKEY file, maybe this version doesn't match to firmware version or some problem on bluez detection. This is the content of my apm6628BT-UART.mx31.psr file: // PSKEY_LC_COMBO_DISABLE_PIO_MASK &0028 = 0200 // PSKEY_LC_COMBO_DOT11_CHANNEL_PIO_BASE &002a = 0011 // PSKEY_LC_ENHANCED_POWER_TABLE &0031 = 0400 0000 3f00 4500 e800 0900 0000 3f00 4700 ec00 0f00 0000 3f00 4a00 f000 1600 0000 3f00 4d00 f400 1e00 0000 3f00 5000 f800 2600 0000 3f00 5500 fc00 2e00 0000 3f00 5b00 0000 5000 0000 3f00 6900 0400 // PSKEY_UART_BAUDRATE &01be = 075f// 460.8 kbaud // PSKEY_HOST_INTERFACE &01f9 = 0001// BCSP link // PSKEY_ANA_FREQ &01fe = 4e20 //PSKEY_USE_EXTERNAL_CLOCK &023b = 0001//true //PSKEY_CLOCK_REQUEST_ENABLE &0246 = 0003 // PSKEY_CLOCK_REQUEST_FEATURES &03b6 = 0000 // PSKEY_PCM_CONFIG32 &01b3 = 00c0 0006 Please, can you give me some tips to fix this issue?
