how to enable LE_CODED in NCS1.8.0 periodic_adv ?

[yoyou]

Hello,

NCS1.8.0 Windows10 X64,

periodic_adv had set BT_LE_ADV_OPT_CODED   and   BT_GAP_ADV_FAST_INT_MIN_2 /* 100 ms   */

periodic_sync scan info "Prim: LE 1M, Secn: LE Coded, Interval: 0x03c0 (1200 ms)"

question:

1. why it still  Prim: LE 1M?

2. why the Interval is 1200ms?

thanks 

Best regards,

yuyou

Hi

You also need to add the CONFIG_BT_CTLR_PHY_CODED=y to add Coded PHY support in prj.conf. You can also add CONFIG_BT_USER_PHY_UPDATE=y here although I don't think it's necessary.

Best regards,

Simon

Hi is the following function missing bt_le_ext_adv_set_data

Hello,

i add bt_le_ext_adv_set_data at line 74,

but the periodic_sync  log show the same;

"Prim: LE 1M, Secn: LE Coded, Interval: 0x03c0 (1200 ms)"

Check the error status when using bt_le_ext_adv_set_data 

[John]

The reason I'm asking is that I have an error which I didn't have prior to SDK V1.8 which causes the advert to fail.

[yoyou]

Hello,

thanks for reply,

i've add check the err code ,but not getting error, it's running.

Best regards,

yuyou
