I was thinking about trying deej on a raspberry pi pico. And thought it would be neat to run it on battery and a Bluetooth connection to the PC. Anyone knows if this is possible?

I have made it, everything works. However, with high-level programming, as far as I understand, it is not possible to achieve a detailed modification of the operation of the microcontroller, so it consumes a disproportionate amount of power. To achieve the result that the project works on a battery, you need to program at a low level, which I don't have time for.

Thanks for the reply. Nice to hear that it works but maybe not so nice with the power consumption. Any idea how much it draws? If I were to put a 1000 mAh cell in, how long would i be able to run it?
Low level programming is sadly out of my expertise

I will soon experiment with ammeter how much power is consumed using nano esp32-s3 BLE with high level code using one library in arduino ide. It is not possible to put the arduino in sleep mode in my current version, because there will be no logical way to wake it up afterwards, but I want to see the real consumption as it is. The only thing I could do is to write optimized code and set values to be sent every 200ms.
At the moment, about 26 hours have passed when the arduino was working continuously from the 13k mAh power bank and 1 led out of 4 that is on the power bank has gone. This is to give a rough idea of how unprofitable the simple solution is without deeper research.
