SDK: 2.2.1.
Tag: 920737.
app: OTA hello-sensor based app.
OTA firmware size ~ 20KB.
===
Problem:
We use NV to store sensor calibration data into NV area; however we find
after OTA, those calibrated data will be deleted and it seems OTA download
also program/erase this area.
Is any other data area as MAC for customer to program their specific data
without reset during OTA?

Hi Leo,
I have two questions:
1. You didn't modified any OTA code (ws_upgrade.c and ws_upgread_ota.c), is it?
2. What size of the "sensor calibration data"?
