CC2745R10-Q1: How to Scan LE Coded PHY Advertisements Using btool

Part Number: CC2745R10-Q1

Hi,
Please tell me how to scan LE Coded PHY advertisements using btool.
I have configured the following settings in btool and verified them, but the scan results do not show any LE Coded PHY devices.
Are there any other settings needed?
I have confirmed that the LE Coded PHY advertisement is being output using Sniffer.

The environment used is as follows:
SDK: simplelink_lowpower_f3_sdk_9_10_00_83
btool: v1.44.04 (BLE5)
Central: CC2745 host_test (using btool)
Peripheral: CC2745 Custom project


Change primPhy1M to Disable and primPhyCoded to Enable in GapScan_setPhyParams

    Hello Rihito,

    I will have to look into this more in depth and get back to you as soon as possible. I will give more information next week.

    Hello Josh,
    After trying various things here as well, I've encountered a new question, so I'm asking.
    To put it simply, it appears to be connected to the Coded PHY, but attempting to send BLE commands to the Peripheral results in a BLE not connected error.
    Details are as follows.
    Using btool, we confirmed that setting GapInit_connect as follows and executing it allows connection to the LE Coded PHY.

    We have confirmed that AUX_CONNECT_REQ/AUX_CONNECT_RSP packets are being transmitted on the Sniffer as well.

    However, I was unable to send commands such as HCI_LE_ReadPhy, ATT_ReadByGrpTypeReq, or Pairing Request.
    Do you know what might be causing this? Is there any additional configuration I need to perform?
    The following image shows the bleNotConnected state when sending a Pairing Request.

    This time, Peripheral is using the sample project (basic_ble), so I'm attaching the environment.
    The changes are as shown in the image below, where we added Coded S2 advertisement.

    Hello Rihito,

    After looking into it more closely it looks like this is a bug in our software. 
    A ticket will be filed and handled in our next release of the SDK. 
    Thank you for understanding and bringing this issue to our attention.

    Best,
