Ok i thing i got it.

I added this prints in case of update:

case BLE_GAP_EVT_PHY_UPDATE:

{

NRF_LOG_DEBUG("-*-*-*-PHY update status:%d, RX:%d, TX:%d",

p_ble_evt->evt.gap_evt.params.phy_update.status,

p_ble_evt->evt.gap_evt.params.phy_update.rx_phy,

p_ble_evt->evt.gap_evt.params.phy_update.tx_phy);

}

break;

and in my nrf connect app i changed the phy after connection (set preferred PHY) and then i saw the the different prints.

There are several optional features in Bluetooth 5, including the 2M PHY. Therefore, you can have a Bluetooth 5 device that does not support this PHY. However, it should be supported by this Pixel phone, so I'm not sure why you are not receiving the PHY update request. This is why there is a feature exchange after the connection established.

Yes.

I own a google pixel 6a and as it seems it supports Bluetooth 5. I am able choose the diffrant options, but i get no prints regarding PHY update request.

As for the second part, do you mean to call phy update from the blinky device it self?

Have you check the feature support for your phone in the nRF connect app to confirm that your phone supports 2M PHY? You can also request a phy update from your peripheral following the PHY Update Procedure.

I connecting using nRF connect app in my Android there is no PHY update.
is there a way to control the app to only use ble5?

The central you are connecting with is probably not requesting a PHY update then. Have you tried usingan Android or iPhone with the nRF connect app to connect to your device?

The latest SoftDevice versions are qualified for Bluetooth 5.1, but you can, of course, test specific features that were introduced in version 5, such as the 2M PHY. For instance, you can monitor the BLE_GAP_EVT_PHY_UPDATE event to see if the PHY is updated to 2M after the connection is established.

Thanks Vidar.

I need to test that my ble5 is working properly, any suggestions of how can i accomplish that?
I tried using the nrf connect mobile app but i am not able to define only to receive ble5.

Hello,

The BLE specification does not permit the use of the 2M PHY on the primary channels. This is why the Softdevice does not allow you to use this configuration.

Best regards,
