BLE low power mode in ESP Wroom32

[rahul_T_T]

Is it possible to use ESP32 BLE alone with a current consumption below 5mA.

From esp32_datasheet, at normal speed it takes 25mA for core, 100mA for BLE Rx, and 130mA for BLE Tx at 0dBm.
So the short answer might be no. EPS32 is not in the same 'battery optimised beacon and bracket' class of those BLE only chips...

I'm more interested to find out the range when set BLE Tx at +12dBm. Is it even possible to +20dBm for 1km? Must be a good time for BLE Mesh which does not work with battery anyway.
