URL: https://github.com/apache/mynewt-nimble/issues/893


   Hello, 
   I'm trying to use nRF52811 with apps/blehci as bluetooth controller which is connected via uart hci.
   Scan on 1Mbps PHY is OK, but scan on coded phy has problem.
   Here is detailed explanation.
   - Environment:
     - mcu nrf52811
     - tool chain gcc version 9.3.1 20200408 (release) (GNU Arm Embedded Toolchain 9-2020-q2-update) 
     - mynewt-core 	1.8.0
     - mynewt-nimble 1.3.0
     - mcu is connected to linux host (Linux 29b841b 4.19.118 armv6l) via uart.
   
     - syscfg setting
   	`MCU_TARGET: nRF52811`
   	`MCU_LFCLK_SOURCE: LFRC`
   `BLE_LL_CFG_FEAT_LE_CODED_PHY: 1`
   `BLE_EXT_ADV: 1`
       - syscfg.vals.BLE_CONTROLLER:
       `TIMER_0: 0`
       `TIMER_5: 1`
       `OS_CPUTIME_FREQ: 32768`
       `OS_CPUTIME_TIMER_NUM: 5`
   
    
   - What I tried:
   Following commands was tested with uart tx/rx is monitored by oscilloscope
     - `btattach -B /dev/ttyAMA0 -P h4 -S 1000000`
     - `bluetoothctl`
     - `scan on`
       - scan start with 1M phy and coded phy (1)
     - `scan off`
     - `hcitool cmd 08 31 03 04 04`
       - set default phy coded only
     - `bluetoothctl`
     - `scan on`
       - scan start with coded phy (2)
     - `scan off`
   - Expected result:
     - scan result of (1) contains both of 1M phy devices and coded phy devices
     - scan result of (2) contains coded phy devices 
     - both of (1) and (2) is extended scan
   - Actual result:
     - scan result of (1) contains only 1M phy devices
     - scan result of (2) contains no devices
     - both of (1) and (2) is extended scan
   
   I think uart hci communication host and controller, extended scan ,and 1Mbps phy are ok.
   I'm wondering if there is bug on coded phy, or I have incorrect configuration. 
   Thanks.
