Hi,

Sorry, yes I meant 125 kbps. This is the only encoding which the Softdevice support sending on, see this post for more details: https://devzone.nordicsemi.com/f/nordic-q-a/37924/the-s140-version-6-1-0-softdevice-full-support-for-s-2-500-kbps

Hi,

S = 8 means 125 kbps, not 250 kbps.

And I am able to change the PHY to 125 kbps when I selecting BLE_GAP_PHY_CODED. it's working.

my requirement is to transmit and receive with coded PHY 500 kbps and 250 kbps.

So is there any option to change the BLE_GAP_PHY_CODED to 500 kbps and 250 kbps?

Hi,

The PHY setting used for advertising will carry over to the connection. You can try this out with the example I uploaded in the other thread I linked to.

Hi Vidar Berg

Is the phy 250 kbps is only for advertising right?

Is the stack will support both transmission and reception with phy 250 kbps?

Hi,

Only 250 kbps (S=8) is supported, and this mode is enabled by selecting 'BLE_GAP_PHY_CODED' when you initialize advertising.
