from the image which you have posted in the forum (sendsms53.jpg) I see that you do not use my program for receiving text messages so I do not know where is the problem in my program. Most likely your modem is not initialized well. Therefore, before starting my program set the breakpoint in " GSM init serial port.vi" and perform a program step by step. Place the probe in the Error Cluster Line and tell me the error message.

At the same time I posted a simple program for sending SMS messages. Try this program and tell me the result.

In the LabVIEW load "GSM init serial.vi" only. Put two probes on the error cluster before and after the "GSM remove echo.vi" as I did it.

Choose proper serial port and start the subVI. Send me a picture of the block diagram of Init subVI like I posted on this forum. If  there is an error it means that the modem is not recognised by the program. Send me this information as soon as possible.

 

Also try your modem with the Hyper Terminal. Enter AT end press Enter button. If you get OK then your modem is working fine. But if you don't get enything that means that the modem is working with different baude rate. Read the sim900 manual .

 

Synchronization between DTE and DCE:
When DCE powers on with the auto bauding enabled, user must first send “A” to synchronize the baud rate. It is recommended to wait 2 to 3 seconds before sending “AT” character. After receiving the “OK” response, DTE and DCE are correctly synchronized. The more information please refer to the AT command “AT+IPR”

Hi, 

 

go to my website  https://sites.google.com/site/tstalevski/ and download all subVIs and main program. 

Maybe you should change some parameters in the Init serial port subVI. 

 

regards
