1. change gap btc args to union to decrease the dram occupied by btc args
2. actually use individual args for every action is the best way(decrease the dram occupy), but for writing code easily and the style, use union
3. gatt server/client should do the same work
Docs: new documentation and warnings cleanup
This change set
- adds a high-level description of application startup flow. Some parts are missing, but hopefully we can use this description as a base to expand on.
- adds a few notes about memory regions and their use in ESP-IDF.
- add SPI flash and partition APIs page
- fixes all Doxygen warnings in header files
- enables build failures on new Doxygen warnings
See merge request !201
Required at project level because some components use header files in
other components' submodules, and one component with a
submodule (esptool.py) doesn't have or need a component.mk.
1. Actually, btc & api are the same module thing. So the type defined in api header file can be included by btc c/h files.
Besides, why btc & api should be separated, because that user may be aware of api and api refer defines/types, rather than other non-refer things.
All defines/types that user won't use should be put in btc directory (and define with prefix "btc_"), and which will be used by user should be defined with prefix "esp_" .
2. rename attribute value(all is value, not data)
1. which named uuid is esp_bt_uuid_t type
2. which named id is xxx_id_t type, such as service_id_t char_id_t, include inst & uuid
3. share include directory
New makefile component_wrapper.mk allows some variables to be set
before component.mk is evaluated. This properly fixes problems with
sdkconfig being hard to access in all phases of the build.
Including component_common.mk is no longer necessary and will print a
deprecation warning for components which use it.
Reduces number of make invocations, allows variables exported in project
to be seen in all component make processes, not just the main ones.
Also makes a no-op build about 3x faster than it was.
1. add new example for A2DP and the related btif layer source code is ported
2. modification on osi_alarm_new API to support periodic timer
3. enable macro BTA_AR_INCLUDED, BTA_AV_INCLUDED, BTA_AV_SINK_INCLUDED
4. The A2DP example cannot work and can only be built successfuly
