OK i get it.
I have another problem.
I am almost done with the project and now i am test running everything in the integrated form. I was trying the GPS for getting the location co ordinates. My Debug Serial Port is giving me co ordinates too but when i try
AT+CGPSINF=2 for getting GPS co...
<Q>Didn't you connect the SIM module to Arduino PCB ?
Didn't you operate SIM module through Arduino UART ?
Yes I have connected my SIM module with ARduino UART and I am sending AT commands from Arduino
But I have also connected the SIM module with PC using DB9 connector (But I am not sending...
Hi guys,
I think I have resolved most of the problems i was facing. Now i can send the sms easily through the arduino but there is a hitch in this.
I have to connect the serial cable to the computer for this communication. That is, for successful communication between Arduino and SIM 908, I...
OK its working for the moment and now i have another problem.
I have interfaced the DB-9 port of the GSM module with the RX2, TX2 pins of the Arduino Mega 2560.
I have written a code that sends 'AT\r' continuously and observes the response from the GSM module.
Desired Response should be:
AT\r...
[Moved] Arduino serial communication with sim 908
Hi there,
I am working on sim 908 and I am trying to serially communicate with it using arduino mega 2560 . But the problem is, when I send "AT\r" serially I should be getting in response, following:
AT\r
OK\r\n
But I get a lot of garbage
I am...
Re: SIM 908 not responding to AT
Let me check that
But if I keep the modem off for some time like 3 or 4 hours I can use it again without a problem like now I have again got it working
But how can I check the power down condition ?
I didn't send any such commands for that
Re: SIM 908 not responding to AT
Thank you
Once again it started working on a different terminal software, docklight. But after a few hours, same problems appeared again.
yes i tried without changing the baud rate.
at one point it started giving this error that:
"COM port x could not be opened"...
Hi there,
I am working on Sim 908 GSM+GPS module. I wanted to see if it works perfectly with the PC so I connected the module with the PC and ran Realterm (a terminal software). After a lot of tries of entering at\r I finally got the 'OK' response and then I successfully sent a few SMS to a few...
