GSM Module Issue

[Embed]

Hi Friends,

The following is the initialization I am doing on fibocom G610 module

String("AT&F0\r"); //Master Reset
Delay_62ms();

String("AT\r"); // Basic Command ATTENTION
Delay_62ms();

String("AT+CMGF=1\r"); // Text Mode
Delay_62ms();

String("ATE0\r"); // Echo OFF
Delay_62ms();

String("AT+CNMI=3,1\r"); // Receive Unsolicited Interrupt Enable
Delay_62ms();

String("AT+CMGD=2,4\r"); // Delete All Messages With No Conditions
Delay_62ms_Caller(15);


When i send a message as "STS"

Ascii Value of S is 53
Ascii Value of T is 54

The module is reading the message body as following 6 Byte

array_data[1]=0x35 '5'
array_data[2]=0x33 '3'

array_data[3]=0x35 '5'
array_data[4]=0x34 '4'

array_data[5]=0x35 '5'
array_data[6]=0x33 '3'

The remaining data that is date, time and message sender number are in text format only, only the message body as above.

Thank You, Good Day.

Hi Mr. Harald Kapp,

The issue, the module has to read the text as STS, but it is reading as Hex, which i mentioned above.

I am sorry, please be specific,

Thank for your time and attention.

How are you sending the "STS" message?

Hello Mr. Steve,

I am sending that from my personal mobile handset. STS as normal text message.

I think the chip got into some configurations.

Nice to get you in this forum Mr. Steve, Thanks.

Check the documentation very carefully to see what this actually means:

String("AT+CMGF=1\r"); // Text Mode

Maybe there's a problem with it.

Try doing the setup without it and see what happens.

Try using the value 0 instead of 1.
