1. BLE only with 9(max) connection will decrease 3K DRAM
2. BR/EDR only with 7(max) connection will decrease 16K DRAM
3. Any of BLE or BR/EDR connection number decrease will also decrease DRAM consumption
4. Decrease one BLE connection will save about 1KB DRAM
5. Decrease one BR/EDR ACL connection will save about 1.2KB DRAM
6. Decrease one BR/EDR SCO/eSCO will save 2KB DRAM.
7. fix some definition and kconfig
8. remove 1.2k of vhci tx cache and make .bss & .data to heap about 1.4K
9. modify BT Reserved Memory size and modify example to support new bt kconfig
This change adds a check for compatibility between the nvs version
found on nvs flash and the one assumed by running code during nvs
initialization. Any mismatch is reported to the user using new error
code ESP_ERR_NVS_NEW_VERSION_FOUND.
1. fix the bug. Modify the condition that esp_bt_controller_mem_release() shoud be only called before esp_bt_controller_init() or after esp_bt_controller_deinit()
2. modify the example to use esp_bt_controller_mem_release()
NVS is used to store PHY calibration data, WiFi configuration, and BT
configuration. Previously BT examples did not call nvs_flash_init,
relying on the fact that it is called during PHY init. However PHY init
did not handle possible NVS initialization errors.
This change moves PHY init procedure into the application, and adds
diagnostic messages to BT config management routines if NVS is not
initialized.
error
- Fix bug that advertising stop event produced while calling start_adv function
- Modify gatt server adv data and scan rsp data raw setting
- add create attribute table error msg
- Delete redundant printf in previous commits
1. indicate adv/scan start complete success or failed
2. controller do limit of adv/scan concurrence, so add some codes to report adv/scan start failed or not.
1. add new APIs bt controller enable/disab/deinit
2. make bt controller work need to call two APIs of esp_bt_controller_init and enable
3. modify phy init to make mac reset once
