Hi All,
Please excuse my noob-ness - relatively new to electronics, getting back into coding.
I have a GPRS shield that is attached to a Uno R3.
I am sending SMS messages no problems, but my project requires me to not have to manually turn on the powerkey on the GPRS shield each time I wish to use it.
Hence, keen to get the software trigger working.
I have reviewed the post Power up GSM Shield with Software - Programming Questions - Arduino Forum , but my board doesn't look the same at all.
Photo of my shield attached.
My questions being:
Should I use the soldering iron to join R13 on the board to allow for this? (Don't want to just start hacking away with the soldering iron)
As the board doesn't sit on top of the Uno R3, where should I plug the output from D9 into the shield?
Once again please excuse my no doubt silly questions. Trying to figure this out as my first project, might have bitten off more than I can chew.
Thanks for any assistance.
Travis
*Attaching the photo keeps failing a security check, not sure why. I'm using the SIM900 V1.0 Shield that is identical to this one:

Well, which is it? Does the shield attach to the Arduino or not?
I have the Shield attached to the UNO through Arduino via patch wires. The shield and Arduino are working together allowing me to send SMS.
This is what my project currently looks like - bit of a mess as the shield doesn't stack.
#Hopefully the photo uploads this time.

Why not? The whole purpose of a shield is so that it DOES stack.
How are you powering the shield?
PaulS:
Unfortunately, some shields have tall components that prevent it. I suppose you could pop in an extra set of connectors to increase the space between the boards.
I'm powering it through the Arduino board being patched to the shield.
The GPRS shield is working fine if I manually start it using the power button
Any one got any ideas on why I can't get the shield to power up through software?
I've confirmed that the software is sending the appropriate signal to the shield.

That's as useless as saying "I've got it connected with some wires".

What power button?

Yes.
I've confirmed that the software is sending the appropriate signal to the shield.
Well, then clearly your shield is defective. Either that or what you think is the "appropriate signal" isn't.
