ESP32-C3 power consumption chart

Hi,

In ESP32-C3 datasheet there is current consumption data (tables 15 and 16). Unfortunatelly I can't find data related to Bluetooth Low Energy. Do you have it?

To be honest, I tried to start two applications:
1. Wi-Fi performing continuous passive AP scan (permanent Wi-Fi RX)
2. BLE passive beacon listener (permanent BT RX, I am not using duty cycle).

In both cases current consumed is equal, ~78mA. I think there may be something wrong in case of Bluetooth LE, as by definition it should be less power hungry.

BLE on ESP32 was never good with power consumption, see https://github.com/espressif/esp-idf/issues/947

Since C3 numbers regarding bluetoth LE are missing and not promoted anywhere I'd guess it is equally bad - single digit mA average even with external 32kHz crystal, probably nowhere near few microamps that other platforms consume with BLE advertising on or connection established.

Hmm single digit mA would be excellent for me. Currently I have ~78mA while Bluetooth is constantly (100% duty cycle) listening for beacons.
