Reading Messages from MTCMR-H5

[Noelia Soliz]

Hi, I’m having problems to set correctly the modem to be able to read incomming messages, so far Im receiving SMS like this

AT+CMGL=”ALL”

+CMGL: 1,”REC READ”,”_Videotron”,””,”13/05/01,15:13:28-16″

004200690065006E00760065006E0075006500200073007500720020006C00650020007200E90073

0065006100750020006D006F00620069006C0065002000640065002000560069006400E9006F0074

0072006F006E00210020005600690073006900740065007A00200076006900640065006F00740072

006F006E002E0063006F006D

I’ve already changed the Mode to Text. Can anyone help me??

Do you know if this was a concatenated SMS?

Were there other related SMS messages before or after this message or others that hadn’t yet been received?

[Darrik Spaude]

By the way, if it is a concatenated SMS message then switch the device to PDU mode and read the PDU message. Convert the PDU data to text using a PDU decoder such as the following:

If it appears to be a meaningful message then likely it is a concatenated SMS.

The secondary check would be to put the SIM in another device and view the same message. Does it appear as normal meaningful text in text mode?

Thanks Darrik for your answer, there isn’t any message that haven’t been received, listing ALL the messages I can “see” them all, that is in the way that I showed you before. If I change the mode to PDU, and translate the message with a PDU decoder like this one http://www.diafaan.com/sms-tutorials/gsm-modem-tutorial/online-sms-pdu-decoder/ is working at perfection, but isn’t the modem suppose to be doing this decodification for me??

I’ve already change the following settings in it:

AT+CNMI=1,1,0,0,0

OK

AT+CSCS=”PCCP437″

OK

AT+CPMS=”SM”

+CPMS: 3,40,3,40,3,40

OK

AT+CMGF=1

OK

I also tried the SIM in my personal phone and all the messages are normal.

I think that I’d might be missing some setting in the text mode, but I really don’t know what else to try!

[Darrik Spaude]

What device are you sending messages from?

What carrier are you using?

Have you tried sending a text SMS from the MTCMR-H5 to itself? Does that work as expected?

[Noelia Soliz]

I was sending messages from an HTC phone with settings in Spanish, I changed that configuration and now I’m able to see them correctly, I tested with another phone with settings “french” also and the messages with “french” characters are shown like the first one that you saw before, but the messages with out it are correct.

We can’t predict or limit the devices that are going to send messages to the modem, so I think I’ll have to work with PDU mode and decode it inside the code.

Thank you very much for your help Darrik!
