我想从手机发送一个文件到DA14585。
如果我设置DA14585的max_mtu为255，每次应用程序发送240字节到DA14585，直到文件已经传输。
连接间隔是40ms，我不确定每个连接间隔有多少数据包(可能是6个?)
每个包包含20个字节，对吗?
6包* 20字节= 120字节，所以240字节应该发送约80ms，这是真的吗?
我使用一个调试引脚来估计，我们发现DA14585接收240字节的数据大约每40毫秒，为什么?< / p > < p >谢谢。< / p > < / div > < / div > < / div > < div class =”字段field-name-field-forum-keywords field-type-taxonomy-term-reference field-label-above”> < div class = "字段标签" >关键词:,< / div > < div class = "字段条目" > < div class =”field-item甚至“> < a href = " / resource-keywords / mtu-packet-connection-interval”“=“skos:概念”属性=“rdfs: label skos: prefLabel”数据类型= " " > MTU包连接时间间隔< / > < / div > < / div > < / div > < div class =”字段field-name-field-device field-type-taxonomy-term-reference field-label-above”> < div class = "字段标签" >设备:,< / div > < div class = "字段条目" > < div class =”field-item甚至“> < a href = " /分类/ / 1491”一词typeof =“skos:概念”属性=“rdfs: label skos: prefLabel”数据类型= " " > DA14585 < / > < / div > < / div > < / div > 2017年11月28日星期二05:07:39 +0000 stanley_yeh 118692年https://support.dialog-semiconductor.com https://support.dialog-semiconductor.com/forums/post/dialog-smartbond-bluetooth-low-energy-%E2%80%93-software/question-about-mtu#comments
