2.FUNCTION DESCRIPTION
2.1. WirelessNetworking
Product is connected with serial devices and GPRSnetwork and communicatewith
remote server through public network. It is suggested to use build-in TCP/IP protocol
stackto achieve remote control and monitor through UDP/TCPconnection with server.
Figure 5. GPRSwireless network
2.2. Work Mode
2.3.1. Support single and multiple connecton
Single connection: build only one connection (UDP/TCP)
Multiple connection: maximum eight connections (UDP/TCP, AT+SOCKA, AT+SOCKB,
AT+SOCKC)
Note:
Recommendto sendUART data every 1000ms to device, otherwise may lost some
packet.

4.AT+INSTRUCTION INTRODUCTION
4.1. Configuration Mode
When HF2111 power up, it will default works as transparent transmission mode, then user can
switch to configuration mode by serial port command. HF2111 UART default parameters setting
as below figure,
Figure 6. HF2111 Default UART Port Parameters
In configuration mode, user can setting the product through AT+instruction set, which cover all
web page setting function.
4.1.1. Switch to Configuration Mode
Two steps to finish switching from transparent transmission mode to configuration mode.
UART input “+++”, after product receive “+++”, and feedback “a” as confirmation.
UART input “a”, after product receive “a” and feedback “+ok” to go into
AT+instruction set configuration mode.
Figure 7. Switch to Configuration Mode
Notes:
1. When user input “+++” (No “Enter” key required), the UART port will display feedback
information “a”, and not display input information”+++” as above UART display.
2. Any other input or wrong step to UART port will cause the product still works as original mode
(transparent transmission).

HF2111 GPRS Serial Server User Manual
Shanghai High-Flying Electronics TechnologyCo., Ltd 15/29
3. “+++”and “a”should be input in a certain period of time to make the product switch to
configuration mode. Like the following sequence.
4.2. AT+InstructionSetOverview
User can input AT+Instruction through hyper terminal or other serial debug terminal, also can
program the AT+Instruction to script. User can also input “AT+H” to list all AT+Instruction and
description to start.

4.2.1. Instruction Syntax Format
4. AT+Instruction protocol is based on the instruction of ASCII commandstyle,the
description of syntax format as follow.
Format Description
< >: Means the parts must be included
[ ]: Means the optional part
Command Message
AT+<CMD>[op][para-1,para-2,para-3,para-4…]<CR>
AT+: Prefix of command message;
CMD: Command string;
[op]: Symbol of command operator,
