Iduino Mega R3 not working / GSM module??

[khurram]

Hi,

I bought 5 of your Iduino Mega R3 from Ali Express (alongwith with 5 GSM modules). These were shipped to an address in USA.

I have tried all 5 Iduinos but can't get them to work. They randomly accept the basic LED flashing code (sometimes this works, mostly I get an error even when uploading this). When I try to upload my code, it always fails and gives me the following error:

avrdude: stk500v2_getsync(): timeout communicating with programmer
avrdude: stk500v2_ReceiveMessage(): timeout

I am using the original Arduino software (ver. 1.6.3).

From the forum I see that a lot of people are having issues with the R3 model and that you have been replacing these with an older model?

As I cannot upload my code, I am unable to check whether the GSM modules are working!!

1. Please confirm the board type and COM port are correct in Arduino IDE.
2. When uploading the firmware, don't connect other modules on R3.
3. Keep pressing "reset" button , click "Upload" on IDE, release "reset" When IDE displays "sketch size...".
4. Please try other versions of Arduino IDE.

1- Board Type (Arduino Mega 2560) and Com port (Com 8) are correct.

2- Nothing is attached to the R3 when uploading the code.

3- No effect of pressing the "Reset" button! The IDE remains on "Uploading...", green status bar stops approx 90% to finish, "ON" LED keeps lit up, "TX" & "RX" flash for a split of a second every 5 secs. I have tried two programmers (AVR ISP and AVRISP mkII).
I keep getting the following error message (this is from one uploading try - and still going on...):

Sketch uses 5,286 bytes (2%) of program storage space. Maximum is 253,952 bytes.
Global variables use 367 bytes (4%) of dynamic memory, leaving 7,825 bytes for local variables. Maximum is 8,192 bytes.

Hi,

I have solved the problem - apparently there was an error in the code which was not allowing it to be uploaded! Sorry for the inconvenience.

Can you please send me the wiring diagram to connect the GSM module to the Arduino R3.

Thanks.

Khurram.

[zhangxueyou]

Is this picture clear?

Actually I am using a pcb on the R3 and will not be able to mount the as shown in the picture - I will need to attach them through soldered wires, if you can let me know which wire will go where.

Thanks,

Khurram.

[zhangxueyou]

I can only tell you how to connect with Dupont:

This is great - thank you!!!

[khurram]

One last question - what is the battery slot for? Can I use it without the battery?

[zhangxueyou]

Battery slot is for powering SIM900. You can use it without battery, the power can be from other place.
