Problem with SMS IO Controller

[dario.costa]

Your code please?

Ioannis

Sorry, I have no code, because I found this project here: http://techni.caliti.es/blog/2008/12...ontroller.html

The only things I can do is to decompile the hex file inside the zip file.
I hope aratti (the coder of the project) could help us to understand where the problem could be

Dario, the problem you are facing derives from the different modem you are using in place of Siemens TC35i used in my project.

Your modem very likely requiers a carriage return + line feed (ascii 13 + ascii 10)
where Siemens requires only a carriage return (ascii 13).

From your report, I also understand that also the AT commands are somehow different which make my program useless for that modem.

Verify if I am correct for ascii 13 + ascii 10 modifying the option of hyperteminal and see how the modem respond (check if you have no answer when you send only ascii 13)

The other problem (the bigger one) are the AT commands which seems different from the Siemens and unfortunatly I have not one Wavecom WMOD2 modem to verify the code and eventually change the AT commands structure.

I strongly suggest you to search around for a Siemens TC35i which will solve all your problems without any additional effort.

Finally I fixed all the problem with the Wavecom WMOD2 modem.
I rewrote part of the disassembled code, applying some changes at the AT command for to make that standard AT and not specific for the Siemens.
I added also some delay and at the end all starts to working perfectly.

Thanks a lot
Dario
