Hi,

thanks,

if the project is periodic_adv and periodic_sync,

# ------------FEM--------------adv-----------------

CONFIG_MPSL_FEM=y

CONFIG_BT_CTLR_TX_PWR_DYNAMIC_CONTROL=n

CONFIG_MPSL_FEM_NRF21540_RX_GAIN_DB=0

CONFIG_MPSL_FEM_NRF21540_TX_GAIN_DB=20

        

# ------------FEM-------------sync-----------------

CONFIG_MPSL_FEM=y

CONFIG_BT_CTLR_TX_PWR_DYNAMIC_CONTROL=n

CONFIG_MPSL_FEM_NRF21540_RX_GAIN_DB=13

CONFIG_MPSL_FEM_NRF21540_TX_GAIN_DB=0

   

i want to set maximum statically only for long rang, is it correct?

It looks like periodic advertising is not supported on nRF52 devices. It is supported as an experimental feature on nRF53 based devices.
