Advertisement with LE Coded PHY

Hi,

I have recently been evaluating the nRF52840 for the research purpose. I came across a question related to this product that I could not figure it out myself. 

I noticed that when I use Coded PHY, the advertisement take places in uncoded 1M PHY. But this affects the range, as the advertisement is not in Coded PHY. 

I was reading the Bluetooth standards (version 5.1) and I found out that in section 4.4.2.4.4 of the standard, the advertisement is also possible using ADV_EXT_IND on the LE Coded PHY.

Now the question is, does nordic uses this feather? Can we have advertisements on LE Coded PHY in nRF52840?

Best regards,

Ben

  • Hi Vidar,

    Yes I have changed the type to BLE_GAP_ADV_TYPE_EXTENDED_CONNECTABLE_NONSCANNABLE_UNDIRECTED. 

    "

    adv_params.primary_phy = BLE_GAP_PHY_CODED;
    adv_params.secondary_phy = BLE_GAP_PHY_CODED;

    adv_params.properties.type = BLE_GAP_ADV_TYPE_EXTENDED_CONNECTABLE_NONSCANNABLE_UNDIRECTED;

    "

    But I get this :

    "

    [00:00:00.000,091] <info> app: Preparing the test.
    [00:00:00.000,122] <info> app: Starting advertising.
    [00:00:00.000,244] <info> app: Starting scanning.
    [00:00:00.050,292] <info> app: Device "Nordic_ATT_MTU" found, sending a connection request.

    "

    It found the device but then it stops!!

    Br,
