Use BLE rtc timer to wakeup CPU
endchoice
choice BT_LE_LP_CLK_SRC
prompt "BLE low power clock source"
default BT_LE_LP_CLK_SRC_MAIN_XTAL
config BT_LE_LP_CLK_SRC_MAIN_XTAL
bool "Use main XTAL as RTC clock source"
help
User main XTAL as RTC clock source.
This option is recommended if external 32.768k XTAL is not available.
Using the external 32.768 kHz XTAL will have lower current consumption
in light sleep compared to using the main XTAL.
config BT_LE_LP_CLK_SRC_DEFAULT
bool "Use system RTC slow clock source"
help
Use the same slow clock source as system RTC
Using any clock source other than external 32.768 kHz XTAL supports only
legacy ADV and SCAN due to low clock accuracy.
endchoice
config BT_LE_USE_ESP_TIMER
bool "Enable Esp Timer for Callout"
depends on !BT_NIMBLE_ENABLED
