Fix that when EXT CRYS is configured but not detected, light sleep is still allowed to be used
Closes BT-1877
See merge request espressif/esp-idf!14723
1. Use correct addresses of Bluetooth Low Power Clock registers on Chip 7.2.8 ESP32-S3
2. Disabled CS-RXDONEMSK to avoid RX interrupt flooding during scan event in coexistence scenario
1. Removed the interrupt lock operation during controller enable/disable/reset, to avoid trigger interrupt watchdog time-out due to use of mutex/semaphore in coex_st_set
2. update libbtbb.a to fix the Rx performance issue for CODED PHY, especially in coexistence scenario
free osi_funcs struct memory duiring failure of controller_init when necessary
components/bt: use s_lp_stat.phy_enabled to control the on/off of phy module
clean up style for controller_disable
clean up some empty functions and unnecessary comments
Added async wakeup src "BTDM_ASYNC_WAKEUP_SRC_TMR"
remove use of assert in controller_init, set error code upon some exceptions
move stop esp_timer early to phase0, add state variable wakeup_timer_started
Refactor bluetooth hardware PowerUp/PowerDown functions
component/bt: fix use of a deprecated MACRO "CONFIG_ESP32_WIFI_SW_COEXIST_ENABLE"
component/bt: fix sleep wakeup in controller disable procedure
remove use of s_pm_lock_sem
1. Modified the waking up approach from async to sync: post a message to controller task upon vhci downstream packets or controller disable, and in response, controller task goes through the wake-up procedure
2. Added Controller status check for the esp_vhci APIs
3. Adjust the procedure during controller_init, check the validity of arguments first
Some minor modifications for bluetooth sleep control and configuration
1. use variable flag s_btdm_allow_light_sleep to control the use of s_light_sleep_pm_lock
2. use variable btdm_lpclk_sel to choose bluetooth sleep clock, support only for external 32kHz crystal temporarily
component/bt: improve async_wakeup function
1. check power state first and then decide if wakeup needs to be performed
2. change the meaning of the return value, if wakeup request is posted to controller task, then return true, otherwise return false
put sleep control logics in controller init/deinit/enable/disable together
Use s_lp_cntl struct: replace bool-typed variable sleep_backup_en with s_lp_cntl.mac_bb_pd
Use s_lp_cntl struct: replace bool-typed variable s_btdm_allow_light_sleep with s_lp_cntl.no_light_sleep
Use s_lp_cntl struct: replace global variable btdm_lpclk_sel with s_lp_cntl.lpclk_sel
create semaphore s_wakeup_req_sem only when low power mode is required
Use s_lp_cntl struct: use s_lp_cntl.wakeup_timer_required to control the wakeup timer
use s_lp_stat to replace original state variable sleep_backup_done and s_pm_lock_acquired
one minor change for mac_bb_pd settings init: return error status if memeory allocation failed
If bluetooth modem sleep is enabled and "External 32kHz crystal" is used as bluetooth sleep clock, the power management lock "ESP_PM_NO_LIGHT_SLEEP" in bluetooth is released for the periods of time when Bluetooth enters modem sleep. In this case automatic light sleep is allowed.
1. modify the limit of frames to send to avoid dropping packet on A2DP source due to TX data queue overflow
2. reduce the A2DP source data queue size in order to achieve faster control respnonse
1. Add more notification events to the enum according to the event list in AVRCP specification.
2. Add API and callback events for basic AVRCP target functionalities to do init, deinit, callback-registration, connection status indication.
3. Implement API to set/get supported PASSTHROUGH command on local AVRCP TG, implement callback events for remote passthrough command indication.
4. Implement API to set/get supported notification eventIDs on local AVRCP TG, implement API to send event notifications to remote CT. \
Currently supported event in TG only includes ESP_AVRC_RN_VOLUME_CHANGE(0xd), which can be extended in later commits.
5. Implement callback events for SetAbsoluteVolume command indication on TG.
6. Add limitation of event_ids supported in RegisterNotification command in CT. The supported event_ids include: \
ESP_AVRC_RN_PLAY_STATUS_CHANGE(0x1), ESP_AVRC_RN_TRACK_CHANGE(0x2), ESP_AVRC_RN_PLAY_POS_CHANGE(0x5), ESP_AVRC_RN_VOLUME_CHANGE(0xd).
7. Add feature bit mask in parameter of callback event ESP_AVRC_CT_REMOTE_FEATURES_EVT for peer feature information got from SDP.
8. Add API and callback event to AVRCP CT to retrieve remote TG's supported notification event capabilities.
9. Modify data type for parameter of callback event ESP_AVRC_CT_CHANGE_NOTIFY_EVT.
10. Change AVRCP version from 1.3 to 1.4 for compatibility cause in using AbsoluteVolume feature.
11. Modify local AVRCP device to be category 1 as CT and category 2 as TG that applies to bluetooth headphones or speakers.
12. Update the use of AVRCP APIs and events in the two examples: a2dp_sink and a2dp_gatts_coex, which include the demo of volume control and notification.
1. start an esp_timer on entering sleep to acquire pm_lock before wake up from modem sleep
2. decrease the clock division of XTAL fed to bluetooth low power clock from 32us to 2us period to allow to work under 240MHz Max CPU frequency
3. decrease the minimum sleep duration threshold to allow shorter bluetooth modem sleep period, especially for BLE with short connection interval
4. reconfigure bluetooth baseband(BT-BB) settings after PHY/RF init upon waking up from modem sleep to avoid packet RX/TX performance degradation
AVRCP connection binds to A2DP in current implementation, despite the two profiles are\
independent according to specification. AVRCP connection is not necessary to set-up \
if A2DP connection fails to establish
In opening state of AVDTP connection, if SDP client fails to get valid A2DP service record\
from peer SDP server, then do not initiate AVDTP connection request
In pevious implementation, A2DP sink will register an A2DP source Stream End Point(SEP) although the SEP is not\
supposed to be used. Now remove the unused SEP for source so that only one role of A2DP can be supported at one
time. Service record in local SDP server only includes at most one service for A2DP sink role or source
1. provide options for bluetooth low power mode
2. provide two options for bluetooth low power clock: main XTAL and external 32kHz XTAL
3. provide function and callbacks to control bluetooth low power mode, including enable/disable sleep, software wakeup request, low power clock settings, check power state, etc
4. modify vhci API vhci_host_send_packet to use blocking mode
5. note that DFS and bluetooth modem sleep can not be used together currently.
