IIRC, there is already tool for it (kerio written one?). I haven't implemented this, as I think that artificially "wasting" current misses the point. When you calibrate, you want to use your device as normal as it gets, to have your relative capacity as calibrated value.

f you make current higher than usual, you will get your value rounded down, and during regular usage, you will have to mentally "add" some capacity, when it's down to 6%. The same but reversed, in opposite case. so, IMO, the key is to just - from time to time, when it doesn't require effort - let device discharge to < 3248 mV, after a busy day for device (or few days, as in my case, with ~3300 mAh battery). Once per month, or so (at least once for 32 charging cycles).

Having BME FOSS replacement makes it even easier - you just allow device to gently turn down due to low power, no bme disabling and voltage monitoring (BME replacement ensured, that device will shutdown *after* calibration took place, unless you're pressing it under extreme - like 1A - current draw during end of discharge) things.

Of course, if someone want to volunteer writing a script that matches bnf "architecture" ( ), I'll gladly include it in update, with all credits and kudos - but, myself, I'm not very interested in writing a "forced calibration" script, because, as I said, I think it misses the point of calibration during real-world usage.
