Python calls to Library about arest HOT 20 CLOSED

Hello, thanks for using my library! Actually I had some success with calls from Python, but using the pycurl module (http://pycurl.sourceforge.net/). I used it for automated tests, but now I moved to Node.js for that part.

Here is a function I used to make cURL calls using pycurl:

def curl_call(target, command):

  buf = StringIO.StringIO()

  c = pycurl.Curl()
  c.setopt(c.URL, target + command)
  c.setopt(c.WRITEFUNCTION, buf.write)
  c.setopt(pycurl.CONNECTTIMEOUT, 5)
  c.perform()

  return buf.getvalue()

Then you can do calls with: curl_call('ip_address',"/digital/6/1")

or to get data back using the json module:

answer = json.loads(curl_call('ip_address',"/temperature"))

Let me know if it works!

from arest.

I believe there is a problem with the arduino script.  We get a message of 
{"temperature": 28, "id": "008", "n
when I enter this in the browser.
http://192.168.0.100/temperature
Then the browser just hangs.  We tried to access the CC3000 with 2 different scripts incorporating 2 different URL libraries and it just hangs. 
Any help would be great!

In that case it looks more like an Arduino than a Python problem indeed. Could you give me:

• the Arduino board you are using
• which Arduino IDE you are using

Also make sure you have the latest versions of the CC3000 library & of the aREST library. Thanks!

from arest.

The board is the uno but I do have a Mega2560The IDE is the Arduino 1.5.8 because you had stated that I needed the upgraded version.
Thank you again for such a quick reply. Jade Fischer,

I guess the problem is the IDE indeed. There are many known problems with the CC3000 library + the 1.5.8 IDE. Try with the 1.5.7 and let me know if it works. You can get it from: http://arduino.cc/en/Main/OldSoftwareReleases

from arest.

I had the same problem, also using arduino 1.5.8, I followed
https://forums.adafruit.com/viewtopic.php?f=22&t=49722 and set
#define SEND_NON_BLOCKING 1
in socket.cpp in the CC3000 library, and now the CC3000 and aREST libraries are working together perfectly for me.

from arest.

Thanks Guys I have made the changes and I will try it later. I will let you know what happened.

from arest.

I uninstalled the Arduino 1.5.8 IDE. I then installed the 1.5.7 version from the link above. I then changed the socket.cpp file by adding #define SEND_NON_BLOCKING 1 above #define SOCKET_OPEN_PARAMS_LEN (12) .
I get the same result.

{"temperature": 28, "id": "008", "n

when "192.168.0.100/temperature" is used in the URL. I get the result:

{"humidity": 40, "id": "008", "name

when i use humidity instead of temperature. This looks like only 35 characters can be sent is there a variable that would be set to only allow a certain amount of characters to be sent in json format? Here is the debug info I am getting because I set debug to 1.

Strange, according to the debug part everything works fine, but not in your browser. What browser are you using for the test? Can you try with another one? I have success with Chrome & Safari for Mac.

from arest.

I have used the chromium browser with the raspberry pi and I also hit it with my windows machine with IE and Chrome.  It all shows the same message with only 35 characters.

Thanks for the info, I will try it again with the browser you mentioned and keep you updated!

Thank you everyone that helped. We figured it out. If you change the sendBuffer(client,64,1000); call you will get the whole json message. We first worked with the 3rd parameter and hoped that the delay would let the whole message get sent but it looks like the 2nd and 3rd parameter work together. The best result was with this call sendBuffer(client,64,1000); in the "void handle(Adafruit_CC3000_ClientRef& client) " method.

Interesting, I will test that on the Mega I have available. Can you submit a pull request with your solution? Thanks a lot!

from arest.

Can I send you the file because I don't know how to submit a pull request and I don't want to create a problem with your code.  If you have steps to submit it I am all ears. Jade Fischer,

Sure, just send it over to: [email protected]. I will then test it & push the changes. I need to make sure it doesn't interfere with the behavior of the library with other boards. Thanks!

I sent the file but here is the only change and it is the 2 parameters going into the sendBuffer() call.

Hi, thanks for the details on the changes. I finally got myself a working Arduino Mega to make some tests. Unfortunately I couldn't reproduce the issue you are having, when I call the API from a browser or an app it works just fine with the current state of the library:

{"temperature": 22, "id": "001", "name": "wifi", "connected": true}

The issue I have with the change you proposed is that it nearly doubles the response time of the board (tested with Postman for Chrome), so I can't push this changes. I would really check again that you are using the latest versions of all libraries, the right Arduino IDE (1.5.7). I would also check that you are using the latest firmware for the CC3000 chip. To update it, just use the driverpatch_xxx sketch included in the Adafruit library. Let me know if that helps!

I will check to see if everything is the correct versions. Jade Fischer,
