data mode, the command will execute, and DTU will switch to the command mode, other wise, the command will be ignore.




Setting DTU 4：





After setting and power on, DTU 1 will establish transparent data channel to others DTU. And all DTU 1 serial port income data will output to other DTU serial port as mass-send. And others DTU serial port income data will send to DTU 1 serial port only.

6.4. Point to Multi-Point Master-Slave Mode Setting DTU 1：

Setting DTU 4：





After setting and power on, DTU 1 will establish data channel to others DTU. And all DTU 1 serial port income data (after process) will output to special DTU serial port. And others DTU serial port income data will send to DTU 1 serial port as transparent transmit.

The master DTU serial port income data should as the format below: destination phone number + 0x00 + data. For example: send string “hello!” to 13800000002, the income data HEX format is: <0x31><0x33><0x38><0x00><0x00><0x00><0x00><0x00><0x00><0x00><0x32><0x20><0x31><0x20><0x48><0x65><0x6C><0x6C><0x6F><0x21>

The slave DTU still sending data as transparent transmit.

6.5. Relate Setting

6.5.1. Whitelist DTU support whitelist function. If the whitelist set, only income SMS which phone number in

the whitlist will output to the serial port, other wise the SMS will be ignored. at+csmwl=1,13800000001<cr> // accept 13800000001 SMS only

The whitelist and blacklist should only use one. Avoid logic error.

6.5.2. Blacklist DTU support blacklist function. If the blacklist set, the income SMS which phone number in

the blacklist will be ignore, other wise the SMS will output to the serial port. at+csmbl=1,13800000001<cr> // refuse 13800000001 SMS

The whitelist and blacklist should only use one. Avoid logic error.

7. Device ID DTU support the HEX device ID function. If the device ID set, the device ID will auto added to

the head of sending SMS at+cdidh=303132 // setting device ID “012”

8. Baund Rate at+wopen=0<cr> // switch to background mode at+ipr=115200<cr> // setting baund rate at+ifc=2,2 // RTS/CTS flow control at+icf=3,4 // 8 bit data, 1 stop bit, no parity at&w<cr> // save parameters at+wopen=1<cr> // switch to command mode
