Hello, I see Proximity Tag reference design, when I want to go to the download found some information can't download, need to sign a confidentiality agreement, when I accept the software licence agreement, prompt waiting for the mail reply.How long do I need to wait?
你好，我看到Proximity Tag的参考设计，当我想去下载的时候发现有一部分的资料我无法下载，需要签保密协议，当我接受软件许可协议，提示等待邮件回复。请问一般需要等待多久。
