The retransmission mechanisms of BLE and WiFi are both based on ARQ (Automatic Repeat reQuest), which uses ACK to confirm errors or lost packets. However, there are some differences in their mechanisms. Below, we will conduct a simple comparative analysis. BLE Retransmission Mechanism The retransmission in BLE typically occurs at the link layer and is … Read more
Recently, we encountered a project where the client’s network environment was unstable, leading to occasional packet loss and network jitter. This caused our software client to intermittently disconnect from the server, interrupting ongoing video conferences. This article takes this opportunity to explain in detail the heartbeat mechanism, packet loss retransmission mechanism, and other related content … Read more

The TCP/IP technology, considered one of the great inventions of the Internet era, has profoundly impacted today’s world. After nearly a month of study and exploration, I have a basic understanding of TCP/IP. Since TCP/IP operates in kernel mode within the OS, many details are not perceptible to users, leading to some confusion about TCP/IP. … Read more
