Change Scan Parameters using NCS

Hi,

Yes, it is possible. You can start scanning in 1Mbit then stop and update the scan parameters for Coded PHY then start scanning again.

In the example, only coded PHY is enabled. To enable coded PHY:

.options  = BT_LE_SCAN_OPT_CODED | BT_LE_SCAN_OPT_NO_1M

Setting BT_LE_SCAN_OPT_NO_1M will disable 1Mbit, NO_1M means 1Mbit Phy disable:

 /**
     * @brief Disable scan on 1M phy.
     *
     * @note Requires @ref BT_LE_SCAN_OPT_CODED.
     */
    BT_LE_SCAN_OPT_NO_1M = BIT(3),

To use 1M, you can try setting options to NULL.

To update the scan parameters use the function bt_scan_params_set().

Thanks for that.

It doesn't seem quite what I'm after. The scan params for coded PHY and 1mbit look like they are both enabled

I need to scan one and then the other.

Is this possible?

Hi,

I suggest you have a look at this example.

Our system will hopefully never be required to connect to device.

So al that I require is to:

stop scanning

Change to 1Mbit

Start scanning

Configurable Delay

stop scanning

Change to Coded PHY

Start

Hi,

If I understand you correctly, you want to scan oin 1Mbit and then change to CODED PHY while in a connection? or do you want to switch between the two when scanning?

More details about you setup and what you are trying to do will be helpful.
