Hi, is there a way to reduce power consumption of the ESP32C3 (right now it takes 80mA, which I think is a lot) while still being able to Scan and avdertise via Bluetooth?
I think it doesn’t work in deep/light sleep mode. Any other suggestions wise people from the internet?
Hi，
Is it possible to have such an idea: wake up in the case of deep/light sleep through Bluetooth scanning? Due to the complex program logic and other devices on the board, the project will also be connected to other hardware, so the level of power consumption actually needs reasonable control by the user, you can refer to similar articles, perhaps you can open a new post with everyone to discuss how to obtain lower power consumption

That’s a good idea.We have published a contrbutor wanted program, you can change the wiki contents, accept some assignments or share your thoughts with us. We will offer a range of rewards to our contributors.
Have you tried optimizing your ESP32C3’s power settings through Bluetooth Low Energy (BLE) advertising intervals and scan window durations? Additionally, consider reducing clock frequency and disabling unnecessary peripherals. Deep sleep might indeed be disabled during BLE operations due to constant activity. Exploring these avenues could help achieve lower power consumption. Good luck.
hey mate, try lowering the Bluetooth scan/advertising interval and duty cycle. You can also optimize the RF power settings and disable unnecessary peripherals. Check the ESP-IDF Bluetooth power management features for more control.
