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"?
