1*34fd36daSMatthias Ringwald# BTstack Port for POSIX Systems with Dialog Semiconductor DA14581 Controller 2e72b198fSMatthias Ringwald 3e72b198fSMatthias RingwaldThis port allows to use the DA14581 connected via UART with BTstack running on a POSIX host system. 4e72b198fSMatthias Ringwald 5e72b198fSMatthias RingwaldIt first downloads the hci_581_active_uart.hex firmware from the DA14581_HCI_3.110.2.12 SDK packet, before BTstack starts up. 6e72b198fSMatthias Ringwald 7e72b198fSMatthias RingwaldPlease note that it does not detect if the firmware has already been downloaded, so you need to reset the DA14581 before starting an example. 8e72b198fSMatthias Ringwald 9e72b198fSMatthias RingwaldFor production use, the HCI firmware could be flashed into the OTP and the firmware download could be skipped. 10e72b198fSMatthias Ringwald 11e72b198fSMatthias RingwaldTested with the official DA14581 Dev Kit on OS X. 12
