CYW20706, When does BTM_POWER_MANAGEMENT_STATUS_EVT occur?

[Anonymous]

In stack_management_callback function,

When does the event occured,

if p_event_data->power_mgmt_notification->status is 'HCI_MODE_SNIFF',

Does this notification mean that the device is set to sniff mode?

Or does it mean to set the device to sniff mode?

After receiving the event and executing wiced_bt_dev_set_sniff_mode(),

the return value is '8105'(Wrong mode).

I want to reduce power loss by setting sniff mode. How to set sniff mode?

Yes, that event indicates you've already entered sniff mode. In addition to this callback, you can use the following API anytime to check the link mode (in wiced_bt_dev.h):
