HI I have HSDPA 7.2 mbps GSM Modem I wnated to send sms using vb.net of C# device is ok I have tested using hyper terminal only problem is when I type AT+CMGS="[phone]" in hyper terminal and I type message and CTRL Z to end it gives error ERROR 305 "Invalid text format" I been through lots of examples but still could not solve this issue. Is there a way I can find if device supports text mode or PDU mode? I am trying text mode which is easy.

推荐答案

进入文本模式的AT命令是AT + CMGF = 1

和PDU编码是AT + CMGF = 0



但在文本模式下，发送短信的文本编码非常重要。

标准GSM编码是AT + CSCS =GSM



希望它可以提供帮助！ :-)



为了安全起见，从AT&F开始

The AT command to get in Text Mode is AT+CMGF=1
And PDU encoding is AT+CMGF=0

But in Text Mode, encoding of the text when sending a SMS i important to.
Standard GSM Encoding is AT+CSCS="GSM"

Hope it can help! :-)

And to be on the safe side, start with at AT&F
