Feature description
I'm trying to optimize power consumption for a battery powered device that uses BLE (and occasional WiFi) using a ESP32-P4 + ESP32-C6 as the esp-hosted slave.
I've been experimenting with menuconfig settings. I enabled a few settings that seemed to save 10-20mW while BLE is connected.
CONFIG_BT_LE_SLEEP_ENABLE=y
CONFIG_ESP_SLEEP_POWER_DOWN_FLASH=y
CONFIG_ESP_PHY_MAC_BB_PD=y
CONFIG_PM_ENABLE=y
CONFIG_PM_DFS_INIT_AUTO=y
I'm opening this issue to discuss if these should be the default or if there's any drawback to these. I'm also curious if there are other settings I should experiment with to decrease power consumption. I don't have a great way to measure the C6 power consumption (separately from the P4) but I can probably rig that up if necessary.
It would also be really helpful to have approximate benchmarks of power consumption in various states in the docs.
Use cases
Longer battery life and better documentation!
