Through what at does Huawei c88 12 send SMS instructions?

Hello, first of all, thank you for your support to China Telecom.

1)AT+TEL= destination address input to set the destination address for receiving short messages.

2)AT+MODE= enter coding mode.

* * * There are four encoding modes: UCS2, 7BIT, 8BIT and TEXT.

◆UCS2 coding: The module is set to UCS2 coding with PDU coding by default, and can send any Chinese and English characters, but only 70 Chinese and English characters at most. Here, an English letter, a Chinese character and a data byte are all regarded as one character.

◆ 7-bit encoding: 7-bit encoding is used to send ordinary ASCII characters. It encodes a string of 7-bit characters (the highest bit is 0) into 8-bit data, and every 8 characters can be "compressed" into 7. This coding method can send 65,438+060 bytes at most, but Chinese characters can't be sent or the sent Chinese is garbled.

◆8-bit coding: 8-bit coding is usually used to send data information, such as pictures and ringtones; With this coding method, you can send 140 bytes at most, but you can't send Chinese characters or the Chinese you send is garbled.

◆ Text encoding: The text mode is relatively simple, which is not suitable for custom data transmission.

Domestic mobile phones are basically not supported, mainly used in Europe and America.

We can use the AT+MODE command to set the user's demand for sending data for various purposes.

3)AT+SEND= enter the message content.

The content of the short message can be any character, including Chinese characters, English, binary numbers and so on. After receiving this instruction, the serial port of W5360 module will send the data directly to the destination address in the form of short message through gsm network. The destination address can be mobile phone, PHS, network, foreign gsm mobile phone, and of course it can also be sent to another W5360 module.

I hope the above information can help you.
