Hi @cksung,
It looks like any device connects to the BC module, the volume gets set to whatever default value is in the BT_VOL_CONFIG so <default_hfp_volume> might affect both. I don’t get the relevant information in BC127 document so if you need more detail please contact your reseller or distributor directly for technical support
Thanks
It seems only affects the speaker volume value, the mic volume is not changed.
