[SOLVED] Battery voltage not reported

Post by ledvinap »

Hello, I just assembled crazyflie and flashed newest firmware. Everything seems to work (waiting for controller, so no flight test), but battery voltage in cfclient is reported as 3000mV and when charging, there are only short blinks of green led. I can power CF from battery, it turns on and can connect to cfclient. Battery voltage is about 4.16 when running.
Is this expected behavior? Or is there some fix?

If you are connected to the client and in the meanwhile you are loading the battery then the green LED is blinking only very short. Is it that what you asked?

Thanks, I missed that.
So the remaining problem is that battery voltage is reported as 3000mV in cfclient most of the time, only during flight I get some other value ...

What is your definition for running? Is the battery bar shoeing values over 4 volts or not?

Seems that battery voltage over 3.999V is not displayed in cfclient binary version cfclient-win32-install-2013.4.1.exe. Using repository version fixes this ...

Okay that is because you have an older version of the cfclient. In the newer version is my fix included (battery shows up to 4.2V).
Maybe someone can create a exe file or i do so this evening if i have time.

No problem for me. But it is a bit confusing if you follow instructions letter-by-letter (= relax mode on ;-) )
