It can both send file to the platform and download file from platform when these two parameters are not set. My question is that it can send file to the platform with a faster transfer speed I want. I know that it will Divide files into multiple blocks to transmit.And when I download file from platform repository to my device running C SDK. It always wait a mini time when transfer a message. So, the download speed is very pool. It seem I can't download file via this way~
could you tell me what wrong of this ? Look forward to your rely!!
