How to config the code to support Coded PHY

[Tom.Fu]

Dear Support Team

We would like to test the long range with the nRF5340 DK and nRF52833 DK, the nRF5340 DK runs the central_uart sample and the nRF52833DK runs the peripheral_uart sample in NCS. 

I used the below fouction update_phy() to update the PHY to Coded PHY and I call it from the callback founction connected() like the second picture below.

But the PHY couldn't be updated to the coded PHY.

I do no modification in the central_uart sample. The enclosed file is my peripheral_uart code. Could you guide me how to implement the Coded PHY between the central and the peripheral? The NCS version I use is the v2.4.0. Many thanks.

Hi there,

I think you need to modify the central example a bit to allow for PHY updates, first you can try to add CONFIG_BT_USER_PHY_UPDATE to the prj.config file. Secondly, you can look at the throughput example that allows for phy update to coded phy, you can compare that example with your code,
