I run your code on my WisBlock with the following small change by (trying to make) X negative and then print out the values before adding them to the payload:
x_axis = -13 * 100;
y_axis = 14 * 100;
z_axis = 15 * 100;
data = "Tem:" + String(temp) + "C " + "Hum:" + String(hum) + "% " + "Pres:" + String(pres) + "KPa " + "Gas:" + String(gas) + "Ohms" + "Device_Latitude: " + String(device_latitude_unit8) + "Devic_Longitude: " + String(device_longitude_unit8) + "Battery=" + String(vbat_per_unit8);
Serial.println(data);
Serial.printf("X %d Y %d Z %d\n", x_axis, y_axis, z_axis);
And it runs just fine, it does not crash. But of course the X value is very high, because x_axis is an unsigned int, so it converts the negative number to a very high value.
