Micro-cntroller with low-power bluetooth module

I am trying to transmit sensor data (Analog temperature sensor) for few meters. I am using a very weak battery (Bio-battery) (3V - 5mA) with an energy harvesting board. I am looking to use it to power up the sensor + micro-controller (wt. Bluetooth). I have found Arduino nano 33.

However, I am interested if anyone knows of another controller with Bluetooth that consumes less power as a Whole!
