Hallo,
habe mit folgendem sketch das Problem, das unsinnige Batteriewerte 150 bis 153% angezeigt werden.
// Enable debug prints to serial monitor

// Add it to array so we get an average of 3 (3x20min)
batArray[batLoop] = batteryPcnt;
if (batLoop > 2) {
batteryPcnt = (batArray[0] + batArray[1] + batArray[2] + batArray[3]);
batteryPcnt = batteryPcnt / 3;
if (batteryPcnt > 100) {
batteryPcnt=100;
}
Serial.print("Battery Average (Send): "); Serial.print(batteryPcnt); Serial.println(" %");
sendBatteryLevel(batteryPcnt);
batLoop = 0;
}
else
{

}
sleep(SLEEP_TIME);
}
Laut dem Sketch dürfte doch garnichts über 100% angezeigt werden oder?
Sp siehts in der Konsole aus:
Battery percent: -81 %
Battery Average (Send): -105 %

So sieht es besser aus.
