    Elad Raz92038
    Hi Gray, There are 2 parts to my answer: HW FC - This is not needed. TX/RX connection is enough. It will also work on high-baud rate (3mbps). Remember that the BT starts with 115200 and during the init-script (Commands/ROM pacthes) one of the first commands is "switch" to high baudrate...

    tom tom101167
    The chipset is OMAP3630+ WL1271+TQM679002. But the sensitivity of BT is only about -70dBm. Single_slot sensitivity will pass the spec which is -70dBm, but the Multi-slot sensitivity always fail. We have supply power of WL1271 by single battery, it seems has no use. The circuit has almost no match...
