At the moment I'm building a small BLE circuit and wondering what the average power consumption is over time. It's not very steady since there are power peaks when there is a bluetooth connection or when it's advertising.
I'm looking for a simple (preferably) cheap device I can put between the battery and circuit to measure the consumption over 24 hours. I know there are these small USB dongles which do this for USB devices: link to device.
Is there something like this that is not USB dependant and works standalone (which doesn't cost hundreds of dollars)? ( I have a multimeter but that only measures current and can't log anything)
