The options for powering bluetooth using batteries for arduino nano 33 iot

hi all i tried using 2 cr2032 feeding it into the vin port and gnd in the nano and it can't seem to detect the bluetooth.

when i power it up using power bank into the usb port, the bluetooth is detected.

i searched for quite a few posts and the options are 9v battery?

can anyone confirm this?

are there any options as well? for aa batteries and aaa batteries.

the main of this project is to make the smallest working bluetooth nano, so for the power, it should be the smallest and hence the reason why i go for cr2032 batteries just to realize it's not working.

Don't go for 9 volt fire alarm battery. You need to get more current than that cell delivers.

Although we are speaking in terms of very small quantities, the whole thing provides up as well Germany VPN think about the antique announcing approximately a person relieving their bladder into the sea. How an awful lot more energy? I don’t recognize, try it and spot.
