1. Modify esp_bt_controller_mem_release() to release BTDM BSS and Data to heap if
ESP_BT_MODE_BTDM mode is passed to it
2. Add a new API esp_bt_mem_release() which internally calls
esp_bt_controller_mem_release() with the provided mode and then if mode
is ESP_BT_MODE_BTDM, releases BT BSS and Data to heap.
Background:
For Wi-Fi and BT/BLE applications, for e.g. the usecase is like when
Bluetooth is used for provisioning and once the device is connected to the Wi-Fi
AP, we can turn off Bluetooth completely. In such scenarios, it should be possible to
reclaim all the memory of Bluetooth. Although, currently this does not
happen.
Experiment:
Made the following modifications to examples/bluetooth/gatt_server :
1. Added support of simple_wifi to it
2. Moved all the bluetooth related code under CONFIG_BT_ENABLED config
option
3. Calculated the free heap in 2 similar scenarios:
i. Disabled BT (CONFIG_BT_ENABLED undefined) and checked the free
heap after STA connected
ii. Kept BT enabled and disabled it after STA connected and checked
the free heap
Ideally, the numbers for i., ii. above should have been similar. But
there was a delta of almost 30-31K. (i. > ii.)
4. Through make size-components checked the common BSS for libbta.a and libbtdm_app.a
and found it to be almost 30K. Data is around 1K
Solution:
1. Modified the linker script to mark the BSS and Data for these libraries and
free it when ESP_BT_MODE_BTDM mode is passed to mem release APIs.
2. Verified that the free heap is comparable for i. and ii. above.
Note: It is known that once this is done, Bluetooth can only be used
again post reboot.

1. fix BLE connection missing in coex mode
2. modify other parameters to make coex priority more reasonable
3. fix modem sleep procedure trap cause Wifi disable RF when BT is
working. Such cause that BR/EDR is difficult to be connected, BLE
connection stability decrease and so on.
4. modify BR/EDR coexist duration to imrove BR/EDR connect success
ratio.
5. Due to the hardware coexist bug, BLE scan interval/window should
be less than 0x100(about 160ms). Therefore, it will cause BLE cannot
scan any advertising packet while WiFi have higher priority
behaviour(such like RX beacon, scan, TX/RX VO packets and etc.).
1. esp_ble_remove_bond_device will only remove BLE bond key and disconnect BLE device.
2. esp_bt_gap_remove_bond_device will only remove BT bond key and disconnect BT device.
* a missing pointer increment caused error, if available was > 0 after the first iteration of while(available) loop.
* changed memory allocation strategy from large fixed size (RFCOMM_DATA_BUF_SIZE) to just the needed
size, which will be below MTU
Cherry-picked from https://github.com/espressif/esp-idf/pull/1923/
Earlier they have to be selected at the compile time through sdkconfig.
A2DP sink and source application tested with this change.

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.
As of now, when Bluetooth debugs are enabled, all the messages are
mapped to BT_PRINTF which is mapped to ESP_LOGE. Hence, make monitor
shows all logs in red color which might lead to missing the actual
errors
This patch maps the Bluetooth messages to appropriate ESP_LOG* messages
and improves readability.
Also, make the BT trace level be configurable in menuconfig, so that
each layer of bt trace can be enabled/disabled.
Finally, add debug log control for BTC, OSI, BLUFI and clear up
Bluetooth debug logs.
So, with this the method of enabling Bluetooth logs is as follows:
1. make menuconfig -> Component config -> Bluetooth -> Bluedroid Enable
-> BT DEBUG LOG LEVEL -> set trace level for every layer of BT

characateristic
1. In addition to mentioning in the documentation, use the standard appearance
values already present and return appropriate error in case an incorrect
value is passed
2. Add ESP_BLE_APPEARANCE* macros corresponding to BTM_BLE_APPEARANCE*
and use them from the API instead
3. Add the missing appearance parameter values from
https://www.bluetooth.com/specifications/gatt/viewer?attributeXmlFile=org.bluetooth.characteristic.gap.appearance.xml
4. Fix some minor typos
