is CAM350 a PCB design software?  (Like Eagle?)
CAM350 is a gerber viewer software. it can be used to check whether the PCB designed ok or not.

suggestion for Elecrow-

offer more board sizes..
**Bonus to multiple size/dimension offerings, NOT just square sized, but rectangle sized too for fair pricing and not over charging for not being 'square'

@Elecrow-

adding these other sizes/dimensions options will help get more customers... (I would have used ya over SEEED if the sizes were available this time) smiley

 Elecrow also provide the following selections.
5cm x 5cm           
5cm x 10cm         
5cm x 15cm         
5cm x 20cm

10cm x 10cm       
10cm x 15cm           
10cm x 20cm

20cm x 20cm
And there is also 5pcs or 10 pcs for your choice.
You can also add V-groove to separate same sub-boards in one PCB panel.
Of course the color is free for sample PCB.
I like their 4 layer PCB service specially. it need only $23.9 for 5X5 cm max board.
it's a great team to provide such great service.

Elecrow can support adding V-groove in one panel for same copies.
Here is a tutorial for how to panelize boards with CAM350.

Hope you find it useful!

I see the tutorial used the Hardware serial port, and I have test code, it works fine,
You can check it, you will find out what's the problem.
For soft Serial port contact, you can use this code have a look.

Sorry, I don't know how to take net in PC using GSM modem. If you find out the result, please tell me.
Thanks.

The function SubmitHttpRequest() is to visit www.google.com, you can change the URL as you want to visit.

learn more you can watch the AT commands.  There are a lot of AT commands, so it's a little hard.

I think it's the same. But you need to test it yourself.

I add a code here, maybe you can have a try.

+CSQ: 10,0
10 is the signal quality, the MAX is 32.

Did you receive the SMS by the phone?
