The old BME supplied by Nokia would reduce its amperage draw in stages if it detected a low voltage situation, it would remain at this low draw even if the available power increased.
Is there a way to script the new replacement BME to automatically poll the available power say every five minutes to see if more power is now available?
My application is a bicycle hub-dynamo driven USB power converter, it can provide up to 1500mA at 20km/h but if I come to a stop or even slow down this obviously will drop off, the N900 will drop to nearly zero draw and will not recover unless disconnected and reconnected at speed, a difficult trick while moving.
I am sure others are using solar, or even the voltage drop when starting a car might cause the N900 to enter a low amp charge state.
