ME99T is a GPRS/CDMA IP DTU Modem embedded with TCP/IP protocol. It is divided into IP module and GPRS/CDMA module. The GPRS module adopts industrial-grade SIEMENS GPRS module and is compatible with all AT commands of SIEMENS GPRS module. The IP module is based on ARM7 kernel TCP/IP protocol stack control chip, and the software interface is AT+I command set. The two modules are relatively independent, but all standard AT commands are transmitted to GPRS/CDMA module in a transparent manner through IP module. ME99T is usually used for situations where the HOST host does not have TCP/IP protocol stack and uses serial communication. It can simply implement TCP and UDP connections, or through the instruction system to simultaneously establish up to 10 TCP connections and other complex applications, or directly communicate with GPRS/CDMA module to realize SMS, voice and other applications.
