Query "?a"

Hello,

i\'m sending the query \"?a\" to the AX1500 in order to know the Amps flowing from the battery to motors but it returns an hexdecimal value (for example \"05\") which converted to decimal is 5...the problem is that it does not correspond to 5 ampere (I\'ve measured it with a multimeter). How can I do to get the right value (around 1.25 ampere)?

Thank you
Davide

any ideas?

According to the documentation, there is a 10% error margin.
In your case the error is 300%...
Did you install the latest firmware update?

On the AX1500, you need to divide the reply by 4 to get the amps

Hello,

I have the same problem with the HBL2350 and a brushless motor because I put a multimeter to mesure amps and when Roborun is giving to me 4A, the multimeter says 0,86A.
Is any solution to fix that issue? Is something wrong in the motor controller or something else?

Thanks!
