calibration and zero do not work properly, calibration lead to crash(or wdt?)

[Zhaosn]

calibration and zero do not work properly, the calibration problem can be solved inelegantly by changing the if in line 231 to always true. But "TRACK_PEEK_URI" always 0, so the zero button is useless.

change

if (hwTrack->isReady()) {
            doCalibrate = true;

to

 if (1) {
            doCalibrate = true;

or something seems crash when hit calibrate button in browser.

The correct setup process is to set the computer's IP address and port in this screen before setting up the AP, is that right? Because I can't get in this setup screen after connecting the ap (browser input 192.168.1.*). I can now get stable output after modifying it according to the above, but this strange crash is confusing me, the problem seems to be in the "hwTrack->isReady()", the doCalibrate and calibrateMpu() functions not causing the problem.
