Uploading Buffer Data

This API is used to upload buffer data to OBS. During the buffer upload, threads are blocked. They are blocked until the upload is completed. The root directory (location of the target OBS bucket) to which the files are uploaded is configured by the user for each device on the Huawei HiLens console (for details, see User Guide > Managing Data). If the user does not configure the root directory for a device, the files fail to be uploaded.

API calling
hilens.upload_bufer(key, buffer, mode)

For firmware versions later than 1.0.6, use upload_buffer_to_obs(key, buffer, mode).
