* BLE: working version * BLE: cleanup * BLE: update device description and DIS. * BLE: explicitly take semaphore and configure CLK48, bt subsystem status, remove LPM. * HAL: add missing api_hal_bt_is_alive symbol * TODO about valuemutex * duplicate f3-1 (f4) ioc from f3 * regenerate project * use target dir for ble glue path * update f4 from f3 Co-authored-by: coreglitch <mail@s3f.ru>
