Temperature sensor in Da1468x

Hi Dialog,
1, Temperature Sensor
From datasheet, we know these:
• Uncalibrated (3 sigma) accuracy of +/- 17 oC
• Accuracy after 1 point calibration +/- 8.8 oC. (Assuming
perfect reference temperature)
• Accuracy after 2 points calibration +/-4 oC. (Assuming
perfect reference temperature)
2, From DA1468x SDK Features_v3.22, the driver of temperature sensor isn't ready now.
Temperature Sensor Driver No No
3, My question:
1) How do calibrate the temperateure sensor to accuracy of +/- 4 oC when do mass production.
2) When do mass production, Do we need to calibrate every DA1468x chip?

thanks in advance!

built-in temperature sensor

built-in temperature sensor is part of the charging circuit and protects the die against too high temperature,you don't need to calibrate it on vverychip

more info:   In DA14681 - 01

more info:   In DA14681 - 01 silicon, there is no need for the customer to perform any calibration on the each chip, 

calibration factors are already calculated and stored in TCS during chip production.
