Bluetooth Power Save Example
|
||||
=================================
|
||||
|
||||
This example is based on the [bleprph](../bleprph) example to show how to use the bluetooth power save mode.
|
||||
|
||||
If the modem sleep mode is enabled, bluetooth will switch periodically between active and sleep.
|
||||
In sleep state, RF, PHY and BB are turned off in order to reduce power consumption.
|
||||
|
||||
This example contains five build configurations. For each configuration, a few configuration options are set:
|
||||
- `sdkconfig.defaults.esp32`: ESP32 uses 32kHz XTAL as low power clock in light sleep enabled.
|
||||
- `sdkconfig.40m.esp32c3`: ESP32C3 uses 32kHz XTAL as low power clock in light sleep enabled.
|
||||
- `sdkconfig.esp32c3_40m`: ESP32C3 uses main XTAL as low power clock in light sleep enabled.
|
||||
- `sdkconfig.defaults.esp32s3`: ESP32S3 uses 32kHz XTAL as low power clock in light sleep enabled.
|
||||
- `sdkconfig.40m.esp32s3`: ESP32S3 uses main XTAL as low power clock in light sleep enabled.
|
||||
## How to use example
|
||||
|
||||
### Hardware Required
|
||||
|
||||
This example should be able to run on any commonly available ESP32/ESP32-C3/ESP32-S3 development board.
|
||||
|
||||
### Configure the project
|
||||
|
||||
```
|
||||
idf.py menuconfig
|
||||
```
|
||||
|
||||
1. Configure RTC clock source:
|
||||
- `Component config > Hardware Settings > RTC Clock Config > RTC clock source`
|
||||
2. Enable power management:
|
||||
- `Component config > Power Management > [*] Support for power management`
|
||||
3. Configure FreeRTOS:
|
||||
- `Component config > FreeRTOS > Kernel`
|
||||
- `(1000) configTICK_RATE_HZ`
|
||||
- `[*] configUSE_TICKLESS_IDLE`
|
||||
- `(3) configEXPECTED_IDLE_TIME_BEFORE_SLEEP`
|
||||
4. Enable power down MAC and baseband:
|
||||
- `Component config > PHY > [*] Power down MAC and baseband of Wi-Fi and Bluetooth when PHY is disabled`
|
||||
5. Enable bluetooth modem sleep:
|
||||
- `Component config > Bluetooth > Controller Options > MODEM SLEEP Options`
|
||||
- `[*] Bluetooth modem sleep`
|
||||
- `[*] Bluetooth Modem sleep Mode 1`
|
||||
6. Configure bluetooth low power clock:
|
||||
- `Component config > Bluetooth > Controller Options > MODEM SLEEP Options > Bluetooth modem sleep > Bluetooth Modem sleep Mode 1 > Bluetooth low power clock`
|
||||
7. Enable power up main XTAL during light sleep:
|
||||
- `Component config > Bluetooth > Controller Options > MODEM SLEEP Options > [*] power up main XTAL during light sleep`
|
||||
|
||||
### Build and Flash
|
||||
|
||||
```
|
||||
idf.py -D SDKCONFIG_DEFAULTS="sdkconfig.defaults;sdkconfig.40m.esp32c3" set-target ESP32C3 build
|
||||
```
|
||||
|
||||
* `-D SDKCONFIG_DEFAULTS` select configuration file to be used for creating app sdkconfig.
|
||||
* `set-target ` Set the chip target to build.
|
||||
|
||||
|
||||
To flash the project and see the output, run:
|
||||
|
||||
|
||||
```
|
||||
idf.py -p PORT flash monitor
|
||||
```
|
||||
|
||||
(Replace PORT with the name of the serial port to use.)
|
||||
|
||||
(To exit the serial monitor, type ``Ctrl-]``.)
|
||||
|
||||
See the Getting Started Guide for full steps to configure and use ESP-IDF to build projects.
|
||||
|
||||
## Example Output
|
||||
|
||||
When you run this example, the prints the following at the very begining:
|
||||
|
||||
```

||||

|
||||
I (463) NimBLE:
|
||||
```
|
||||
|
||||
## Typical current consumption with management enabled
|
||||
|
||||
| | max current | modem sleep | light sleep (main XTAL)| light sleep (32KHz XTAL)|
|
||||
|-------- | ----------- | ------------ | ---------------------- |------------------------ |
|
||||
| ESP32 | 231 mA | 14.1 mA | X | 1.9 mA |
|
||||
| ESP32C3 | 262 mA | 12 mA | 2.3 mA | 140 uA |
|
||||
| ESP32S3 | 240 mA | 17.9 mA | 3.3 mA | 230 uA |
|
||||
X: This feature is currently not supported.
|
||||
|
||||
## Example Breakdown
|
||||
|
||||
- ESP32 does not support the use of main XTAL in light sleep mode, so an external 32kHz crystal is required.
