Prevent a remote device from doing a Bluetooth Impersonation Attack
(BIAS) by:
- Preventing remote device to downgrade secure connection
feature mask. Secure connection feature mask should remain same or
increase to enabled in link key generation and authentication.
- Doing a mutual authentication during Legacy Authentication.
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

1. add the L1 include path with a prefix, such like osi/list.h, stack/a2d_api.h and etc.
2. modify component, only bluedroid/api/include/api is export to another component and application,
other include path just for bluedroid used
3. put bluedroid/include into common/include/common, so the root directory of bluedroid have no include path.
4. modify doxygen to use esp_bt.h and redirect to
component/bt/bluedroid/api/include/api/
fix compile
1. remove GKI(not use osi_free_and_reset)
2. modify mutex/semaphore to individual directory
3. set osi_malloc as malloc(previously use calloc)
4. change osi allocator debug osi_free
5. fix rebase of remove GKI
- Fix slave initiate service discovery procedure
- Fix master re-discovery every time connection established
- Optimize service discovery char ccc write procedure
- Optimize esp_log_buffer function
- Modify default supervision timeout from 20s to 2s
1. close classic bt, can save 233k code size;
2. close smp module, can save 136k code size;
3. close gattc module, can save 24k code size;
4. close gatts module, can save 16k code size;
4. close the bluedroid stack log, can save 120k code size.
