sending MMS using sim900 or sim300

[rutuja magar]

i want to send an image as a MMS to mobile phone using either sim900 or sim300.

the image has to be given to the GPRS module from hyperterminal. the AT commands given just show that GPRS is connected but does not accept any settings for  URL and server number.

 

Also, i m unsure of the commands i m using for this, any help in this regard will also be much appreciated.

 

 

pl help me

USE THIS COMMANDS FOR MMS FROM SIM900

[priya]

I have used the same code in connecting GSM MODULE sim900A  for sending an image in PC. when i used AT+CMMSDOWN i got CONNECT and then ERROR. What should i do for preventing the error.what does that CMMSDOWN actually mean? Do i have to use any microcontroller?  Will anyone please help me with the code?

[Ganesh Selvaraj]

Did you check the signal strength of the modem? and are you getting just “ERROR” or some number along with it?

[priya]

We checked the signal strength and it is good. After getting CONNECT we just get an ERROR without any number.Actually we didn’t write any image on SIM900.So far what we done is

     i) Connected SIM900 with PC using RS232 cable

     ii) Checked sending an SMS and incoming call.

     iii) Tried the MMS code till the error as we mentioned.

        We have not connected any microcontroller to connect PC and SIM900.

So,How can sim900 download an image from PC??

Please help us.
