What is the interval for the Wi-Fi module to send data frames?

The transmission mechanism of the Wi-Fi module serial port has a certain relationship with the function command:

1. For the commands issued for functions, when multiple DP commands are issued at the same time, in order to ensure the timeliness of control and the user experience, the module is issued without intervals. Therefore, there will be scenarios where sticky packet data is sent;

2. The daily heartbeat query frame is a periodic query every 15s, and the shortest retransmission interval is 1s;

3. For the networking status frames and heartbeat frames, in the scenario of simultaneous triggering, the module sends them at intervals of 100ms.

To sum up, the shortest cycle for issuing module commands can be understood as no interval. Therefore, the data reception and analysis of the MCU also needs to support the scenario of sticky packet data processing.
