About the error of NEW_DEVICE_ERROR, when using OSDK(APPID/KEY) for the first time.

Keywords: NEW_DEVICE_ERROR

When the APPID/APPKEY of the OSDK are used for the first time on the drone, the error of NEW_DEVICE_ERROR prompts that the APPID/KEY needs to be activated.

It is recommended to use DJI Assistant2 for activation, steps:
1. Enable OSDK activation on DJI Assistant2.

2. Run the OSDK application while connecting to DJI Assistant2 to activate, log in to your account with DJI Assistant2
3. Make sure that the app_id and app_key in the OSDK configuration file(UserConfig.txt) are the available.
4. Run the demo or your own application twice. The first time it will still report NEW_DEVICE_ERROR, and please run it again (the latest Master branch version OSDK4.1 only needs to run once).
