1. Improve WiFi throughput in some Classic BT scienarios(idle, inquire scan,
connected, sniff, a2dp pause, etc).
2. Support WiFi + Classic BT + BLE mesh coexistence scienario.
3. Improve WiFi scan and connect succeed ratio in coexistence scienario.
4. Do not support to choose software coexistence preference anymore for it is
determined according to coexistence scienario automatically.
components/lwip: increase TCP send buffer and receive window limitation when TCP window scale is enabled
components/ble_mesh: Fix some bugs about ble mesh
1. fix send acl pkt after ble have sent terminate ind modify min adv interval to 10ms.
Fix A2DP stuck when BLE's interval is too small
Bugfix that bluetooth controller may not be able to enter sleep after end of wake up request
Fix LMP sniff req timeout
1. Fix high beacon and broadcast packets loss ratio of WiFi to make
MDNS test pass.
2. Improve stability of WiFi performance with a little
sacrifice of throughput.
3. Improve BLE advertising and connection performance with dynamic
priority. It sacrifices a little WiFi throughput, but achieves balance
between WiFi and Bluetooth.
4. fix bug bb reset lock flag to avoid bb reset lock unhandle
5. fix bug wifi reset mac cause task watch dog timeout
6. fix bug wifi reset mac position
1. Since BLE full-scan feature for BLE mesh change the controller code cause this problem,
it cause coex semaphore take in "interrupt disable", then it may cause task schedule
and cause crash in freertos
2. Fix newlib lock ISR context and critical section check
3. Fix bt controller ISR context and critical section check
Includes all the latest NimBLE stack changes from idf-v4.0 with few idf-v3.3
specific modifications.
- Addition of nimble component as submodule (`nimble-1.1.0-idf-v3.3`), contains
IDF v3.3 specific minor changes.
- Example applications are identical to idf-v4.0
- Modification in `bt/Kconfig` to accommodate NimBLE as a BT host.
- Backport(v3.3) of IDF MR!6122
- Modifies `smp_utils.c` to add check on encryption key size received from
peer.
- Modifies `esp_ble_gap_set_security_param` API to add minimum encryption key
size requirement.
Remove xtensa/xruntime.h
Fix sending Lmp_feature_req_ext in a loop
Fix 2 bugs in r_ld_fm_sket_isr
fix data loss and send same pkt twice sometimes
fix adv data error in air sometimes
fix adv start/stop crash sometimes
Fix connect fail with some speakers
clear BT/BLE interruots after controller disable
add sco_data_path to be set in sdkconfig and do not reset the value upon HCI reset command
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
This problem may cause HCI send command timeout.
When host call VHCI api to do btdm_wakeup_request, then controller
wakeup process will be handled in ISR and controller task context.
As host task priority is lower than controller task and ISR,
it will cause an incorrect behavior that before VHCI take the
rx_flow_on_semaphore, controller sleep again, then VHCI cannot take
the semaphore and has to wait the automatic wakeup.
