    position.<\/li>\n

  2. Position jumpers next to USB Serial connector J24 to the 1,2 position.<\/li>\n
  3. Position jumpers next to USB 3G connector J4 to the 1,2 position.<\/li>\n
  4. Power up the MTPCIE-DK1 developer board with the MTPCIE Bluetooth\/Wi-Fi capable radio installed.<\/li>\n
  5. Connect computer USB port to the USB Serial J24 USB connector on DK1 board.<\/li>\n
  6. Use commands such as dmesg, lsusb -v, etc to find the ports Linux assigned to the quad uart on DK1.Record the port designation assigned to the second port. For example:<\/li>\n

  7. Copy the file TIInit_7.6.15.bts to the \/lib\/firmware folder of the computer.<\/li>\n
  8. Install jumper JP86(labeled \u201cBT_EN\u201d), then remove it again to toggle the Bluetooth Enable signal for the MTPCIE.<\/li>\n
  9. Enter the following string, substituting the computer’s tty port that corresponds to uart port B on MTPCIE-DK1:<\/li>\n
    \r\nhciattach -s 115200 \/dev\/ttyACM1 texas 3000000\r\n<\/pre>\n
  10. On the Linux computer, enter:\n<\/li>\n
    \r\nhciconfig -a name\r\nExample Response\r\nptg@ptg-desktop:~$ hciconfig -a name\r\nhci0: Type: UART\r\nBD Address: 1C:E2:CC:04:5C:C2 ACL MTU: 1021:4 SCO MTU: 180:4\r\nUP RUNNING PSCAN\r\nRX bytes:1013 acl:0 sco:0 events:30 errors:0\r\nTX bytes:883 acl:0 sco:0 commands:30 errors:0\r\nFeatures: 0xff 0xfe 0x2d 0xfe 0xdb 0xff 0x7b 0x87\r\nPacket type: DM1 DM3 DM5 DH1 DH3 DH5 HV1 HV2 HV3\r\nLink policy: RSWITCH HOLD SNIFF PARK\r\nLink mode: SLAVE ACCEPT\r\nName: ''\r\nClass: 0x4a0104\r\nService Classes: Networking, Capturing, Telephony\r\nDevice Class: Computer, Desktop workstation\r\nHCI Ver: (0x6) HCI Rev: 0x0 LMP Ver: (0x6) LMP Subver: 0x1f29\r\nManufacturer: Texas Instruments Inc.

  11. Verify the remote serial Bluetooth device is configured to wait for a connection.<\/li>\n
  12. Verify the remote Bluetooth device’s MAC address is in the list of detected Bluetooth devices. Enter:<\/li>\n
    \r\nhcitool scan\r\nExample Response\r\nptg@ptg-desktop:~$ hcitool scan\r\nScanning ...\r\nCC:55:AD:2B:53:FA BB 9330\r\n00:18:E7:36:CF:91 DTMVW7JREI01\r\n00:A0:96:0F:B8:2A SocketWireless\r\n<\/pre>\n
  13. Enter the following, where xx represents MAC address of the remote Bluetooth device you set up
    \npreviously:<\/li>\n
    \r\nrfcomm -S connect 0 xx:xx:xx:xx:xx:xx\r\nTo run rfcomm in the background add \"&\" to the end of the string as follows:\r\nrfcomm -D connect 0 00:A0:96:0F:B8:2A &\r\n<\/pre>\n
  14. Open another Linux terminal session and run a terminal program such as minicom at 3000000 bps attached to \/dev\/rfcomm0 port. Use minicom to communicate with your remote device.<\/li>\n<\/ol>\n","protected":false},"excerpt":{"rendered":"
