This product features, in addition to basic serial port, baud rate, parity bit, stop bit, data bit, character and hexadecimal sending and receiving, etc., it also supports script function. What is the use of the script function? When the author is developing IoT products, it is often necessary to fill in the instructions repeatedly when plugging in and out of the module, even if it is selected in the history, it is cumbersome and time-consuming. For example, when developing a 4G shared payment product, when debugging a 4G module, you need to input each time you re-insert: query SIM card status, query signal strength, query whether data services are available, request IP allocation, set MQTT authentication information, and set MQTT will information , a series of AT+ commands such as establishing MQTT connections and subscribing to topics. Therefore, it is very cumbersome to re-enter each input after each dialing and plugging, and scripting is the best solution.
In addition to the functions of the normal version, the Pro version also adds TCP/UDP network debugging function, WebSocket function, serial port⇆TCP remote debugging, data processing also adds numerical increment, automatic reply, CRC check, etc.
However, there is still a big difference between the Pro and the regular version. The underlying structure of the Pro is restructured to solve the problem of getting stuck when receiving data quickly (within 10ms).
