How to setup NRF21540 with CODED PHY

[David Duan]

i devzone

I following the blog (devzone.nordicsemi.com/.../testing-max-range-with-ble-with-nrf21540dks-and-nrf52840-dks) to setup 20DB on 21540 DK (pca10112), it is works fine on NCS 1.9.1

BLE 1M with NRF21540 20DB

however after I change the BLE PHY to coded, looks like the TX power is incorrect. Looks like the NRF21540 not work

Below it is my project, could you please kindly help to take look (NCS1.9.1)

in my project, i only add below marco and follow example peripheral_hr_coded to change the advertising as coded phy

#with coded
CONFIG_BT_CTLR_PHY_CODED=y
CONFIG_BT_EXT_ADV=y
CONFIG_BT_USER_PHY_UPDATE=y

peripheral_uart_code.7z

Hmm, Interesting, I have not tested this myself so I am not sure why it does not work. I can quickly test it tomorrow to see if there is any other configuration that is missing to make it work with coded phy.

Hello 

any update for this ticket ?

Hi, 

Added the below configs to ncs\v1.9.1\nrf\samples\bluetooth\peripheral_hr_coded\ and found the the signal is good with FEM and coded. Not sure what is the difference with your project but the feature of FEM+CODED seems to be working just fine with the samples.

HI Nuguru

could you please kindly provide your peripheral_hr_coded project to me? or your prj.conf

Thanks
