GPRS Module USR-GPRS232-7S3 Introduction of Cost-effective UART GSM Modules
GPRS Module USR-GPRS232-7S33 are Cost-effective UART GSM Modules used for data transparent transmission, which are highly-integrated UART to GSM/GPRS modules. Users can easily make communication with it among serial device, cellphone and network device. USR-GPRS232-7S3 is based on USR-GM3 GPRS module. Clients can use the product to realize bidirectional transparent transmission from serial port to network through simple AT command.
Support GSM/GPRS and 2G/3G/4G card, but don’t support 3G/4G network.
Support 2 sockets, Support TCP and UDP.
4KB cache for each of sockets, user can choose to cache data or not.
Support register packet and heartbeat packet.
Support setting parameters via SMS message.
Support multi work modes: SMS transmission mode, network transmission mode and https D mode.
Support basic and extend AT command sets.
Support class RFC2217, can dynamically modify serial parameter of module via network.
Support flow control: RTS/CTS.
