SIM800C is a quad-band GSM / GPRS module for the castle hole package. Its performance is stable, the appearance of small, cost-effective, able to meet the various needs of customers.
First, SIM800C chip introduction
SIM800C operating frequency of GSM / GPRS 850/900/1800 / 1900MHz, low power consumption can be achieved voice, SMS and data transmission. SIM800C size of 17.6 * 15.7 * 2.3 mm, can be applied to a variety of compact product design requirements .
Quadrature 850/900/1800 / 1900MHz
FTP / HTTP, embedded TCP / UDP protocol
DTMF detection, Bluetooth 3.0 (optional), USB interface
Through the TTL level serial port and external system communication, the default can directly communicate with the 5V system, no level matching. And 3.3V system, 2.85V system communication, the need for a little bit of hardware processing. We will be in the user manual to do a detailed description.
Communication interface (command) for the AT command, that is, the control module to achieve the function is entirely through the AT command to achieve, such as: control module to call ATD *******; (* for each other's phone number). We will provide a complete AT instruction set.
In addition, we will provide some of the common functions of the C program
