ReviewIn the previous article we introduced the background of Bluetooth Le and explained what we will be developing in this series of articles, but there is no actual code. We will correct this in this article, and we will ensure that the Bluetooth operation is decoupled from the UI by defining the Service/activity architecture.Service and Activity CommunicationBefore we go on, I should point out that we ar

. Fragmentation and ReorganizationGroupings defined by the baseband protocol are limited in size compared to other wired physical media. The Maximum Transmission Unit (MTU) associated with the maximum base-band payload (341 bytes in the DH5 packet) limits the efficient use of higher-layer protocol bandwidth, while higher-level protocols use larger groupings. Large l2cap groupings must be segmented into several small baseband groupings before the wireless transmission. Similarly, a large, single

Graduation design is to do the topic of smart home, to do a mobile phone Bluetooth app, and the next computer to achieve data transmission; I've never done Android before, but I'm pretty good with qt,c++, so I use eclipse to feel quite handy, and the Java language is very similar to C + + in many places, so I personally feel , C + + people, Java is certainly not a problem. Not familiar with Java, you can refer to my article Java syntax: different from
