ESP32 Forum

Hello Experts ,
I am using the device esp32-c3-devkitc02 and the device radio current consumption is pretty high for the SOC (ESP32- C3) to run with Coin cell CR2032 ( 3V,220mAh , @max pulse current 10mA).
Is there an option to configure the device TX dBm level from +21 to -24bBm ?
there was a significant current change as you can see form the images upon changing the TX power Level.
i have used 1ohm 3W shunt resistor for current measurement at the low side.

Peak Current of 300mA for +21 dBm Peak Current of 200mA for +18 dBm (although the probes were connected correctly there was a -ve voltage displayed) 1) Are there any way to make it work for with 10mA as max current consumption ( competitive ICs are offering 3-5mA RX current at 0dBm )
2) there was no option to configure the RX dBm level in the configurator

Are there any way to make it work for with 10mA as max current consumption

Unlikely, given that, according to the datasheet and confirmed by my own measurements, the C3 at idle (not sleeping), without any RF enabled, draws about 17mA @ 80MHz. - You could certainly add a low-pass filter in the supply line to limit the maximum current during brief periods of activity.

there was no option to configure the RX dBm level in the configurator

What would that kind of configuration be supposed to do? Defining the power of a received signal? Reduce the power consumption by lowering the sensitivity (gain) of the receiver?
