PAwR subevent configuration in the code but not in prj.conf

[always18]

Hi,my board is nRF52840dK,and the SDK is ncs 2.7.0.

I want to modify the subevent parameters,

Is there any API to modify them in my code but not in prj.conf? such as

CONFIG_BT_CTLR_SDC_PERIODIC_ADV_RSP_TX_MAX_DATA_SIZE and 

CONFIG_BT_CTLR_SDC_PERIODIC_ADV_RSP_TX_BUFFER_COUNT

thanks

Hi,

These configs are build time adjustable only. May I ask why you want to change this in code/dynamically?

Hi，

sometimes AP need to send big buff to ESL in AUX_SYNC_SUBEVENT_IND,such as DFU,It is prefer to adjust the TX_MAX_DATA_SIZE to 244, 

Most of the time,AP only send a little of bytes to ESL, 24 is enough.it is beneficial for ESL to save engergy

So change them in code is useful。

Hi,

I see. However, I am not sure in what way a different buffer sizse would save you energy or give you any other benefits even if you don't need it. Can you elaborate on this?

Hi,

I think,Smaller buffer size of AUX_SYNC_SUBEVENT_IND, less rx window interval for ESL.

Hi,

I see. That is not the case. The scheduler needs to take into account a long packet, but the Rx window (where a transaction can start) is not affected. So unless the actuall packet is larger, the radio is not spening any more time in Rx.
