Tell me i've missed the obvious!

Hello toomuch,

Have you missed the obvious?  Perhaps!    Post the local.py file you are using and let's look at it and help.

I assume you are talking about triggering a GPIO on a button push?  B-2 specifically?

On the app, did you point B-2 to your Raspberry Pi (the system URL?)?  Double check that and make sure that you can access that URL (look at the trouble shooting section of the manual).  Run the server in Debug mode and see if you are receiving the XML.

I don't know what you are doing in your local.py file, but here is what I might try.  Make sure you have an LED connected to the right pin (with a current limiting resistor!).

# B-2 - Blink an LED on the Raspberry Pi, pin 22 (GPIO 25).
if (objectServerID == "B-2"):

                #check for validate request
# validate allows RasPiConnect to verify this object is here
                if (validate == "YES"):
                        outgoingXMLData += Validate.buildValidateResponse("YES")
                        outgoingXMLData += BuildResponse.buildFooter()
                        return outgoingXMLData

# not validate request, so execute
import RPi.GPIO as GPIO
# Note:  BOARD pin 22 is GPIO15
                       GPIO.setmode(GPIO.BOARD)
                       GPIO.setup(22, GPIO.OUT)
                       GPIO.output(22, False)
                       GPIO.output(22, True)
                       time.sleep(0.5)
                       GPIO.output(22, False)



responseData = "OK"
                outgoingXMLData += BuildResponse.buildResponse(responseData)
      outgoingXMLData += BuildResponse.buildFooter()
                return outgoingXMLData


Best regards,

BP

The basic default Local.py file plays a sound through the speaker port. It was done that way because the Raspberry Pi has nothing built in that will work aside from that.

Look at the above Local.py file, hook up an LED and try this.

Toomuchfuel,

Sorry, I wasn't clear. The above wasn't a full local.py file. Just a replacement for B-2 in the local.py file.

In your local.py file, replace B-2 with the above. You should copy the LocalExample.py to local.py and then replace B-2 with the above code.

Best regards,

BP

toomuchfuel,

I took your 2local.py file, renamed it Local.py and executed a button B-2 from RasPiConnect.  Looking at the debug output from the RasPiConnectServer, you have an indent syntax error.

I fixed this indentation problem in your file and then added import time to the headers.  The file now runs correctly

Here is the resulting Local.py file

Toomuchfuel,

What do you mean "Took my App offline"? Are you talking about the iPad App? Your own program?

We need some more information to help you here. Post your errors.

Best regards,

BP

Hi toomuchfuel,

On your raspberry Pi, start the RasPiConnectServer in debug mode (in the configuration file - see the wiki manual), start it in a terminal window and copy and paste the error messages you are getting.

The green dot going red does indicate the server is down, but it doesn't tell us why. The above will tell us why.

Best regards,

BP

If your referring to this line:

# set to True if you wish to see debugging output from the server otherwise False
DEBUG = True

I have it set to 'True' but i do not see any errors coming up on screen?? Does it save to a file somewhere?
