  1. I've been tinkering with AWS IoT in conjunction with CC3200 + Energia for a while now with varying degrees of success. The purpose of this post is using the RESTful API to update a "thing" status in the cloud. The code is listed below and I'm seeing some authentication errors. I was hoping someone can correct me if there are any errors in the way I'm using "client.ssConnect". I used a slightly modified WiFiClient.cpp and WiFiClient.h from here. I know its not a library issue since I'm able to connect using MQTT. char aws_endpoint[] = "xxxxxxxxxxxxxx.iot.us-east-1.amazonaws.com"; if (client.sslConnect(aws_endpoint, 443)) { Serial.println("Connected to server"); String PostData = "{\"value1\" : \"testValue\", \"value2\" : \"Hello\", \"value3\" : \"World!\" }"; request = "POST /things/"; request += thingname; request += "/shadow"; request += " HTTP/1.1"; Serial.print("Request:\t"); Serial.println(request); Serial.print("Post data:\t"); Serial.println(PostData); client.println(request); client.println("Host: "); client.println(aws_endpoint); //client.println(":443"); client.println("User-Agent: Energia/1.1"); client.println("Connection: close"); client.println("Content-Type: application/json"); client.print("Content-Length: "); client.println(PostData.length()); client.println(); client.println(PostData); client.println(); } else { Serial.println("Connection failed"); } Serial.println(); // Capture response from the server. (10 second timeout) long timeOut = 5000; long lastTime = millis(); while((millis()-lastTime) < timeOut) { // Wait for incoming response from server while (client.available()) { // Characters incoming from the server char c = client.read(); // Read characters Serial.write(c); } } Here is the output that I see: RootCA found! Client certificates found! Device ID is: 3250763216 Attempting to connect to WiFi network . Connected to WiFi network: ABCDEFGH Waiting for IP IP is: 192.168.1.107 Connected to server Request: POST /things/MyCC3200/shadow HTTP/1.1 Post data: {\"value1\" : \"testValue\", \"value2\" : \"Hello\", \"value3\" : \"World!\" } HTTP/1.1 403 Forbidden content-type: application/json content-length: 91 date: Tue, 26 Jul 2016 11:46:59 GMT x-amzn-RequestId: 4d5388a9-e3c4-460a-b674-c3f971f3330d connection: Keep-Alive x-amzn-ErrorType: ForbiddenException: {"message":"Missing Authentication Token","traceId":"4d5388a9-e3c4-460a-b674-c3f971f3330d"}
  2. Hi there, Really excited to see the new release of Energia supporting the CC3200 launchpad! I just ordered some for myself. Does anyone know if there are plans to include the SSL demo for the CC3200 in Energia? Thank you!
  3. Hi, I am using the web client demo to send an HTTP GET request to a web server to read the data in json format. However the web server returns an error code 301 page moved error. How do I redirect my request to the new location? Does the ethernet library for TIVA support SSL HTTP GET requests?
  4. I am trying to talk to the Microsoft Azure Event Hub from Energia but I'm a little baffled! Using the WiFi library I seem to be getting a successful connect (returns true) but ... nothing seems to get posted... I am trying to build the message up as in this (javascript) example http://fabriccontroller.net/iot-with-azure-service-bus-event-hubs-authenticating-and-sending-from-any-type-of-device-net-and-js-samples/ but not seeing anything (even failed messages) reported in the event hub. I wanted to stick with Energia rather than switch to anything else, but after a couple of days banging my head on a wall I'm a little suck! Any ideas would be much appreciated (as I'm probably doing something dumb!) if there's a way to debug this / get error messages from the connection or the attempt to post that would be a huge help... Gotta use the Azure end point for this, so that's the one constant. char sas[] = "SharedAccessSignature {sig from the generation example}"; char serviceNamespace[] = "{ns}.servicebus.windows.net"; char hubName[] = "{hub}"; char deviceName[] = "device01"; void loop() { ////// WiFiClient client; float t = 10.1; client.stop(); // if there's a successful connection: if (client.connect(serviceNamespace, 443)) { Serial.println("connecting..."); // send the HTTP POST request: client.print("POST /"); client.print(hubName); client.print("/publishers/"); client.print(deviceName); client.println("/messages HTTP/1.1"); client.println("Host: www.arduino.cc"); client.println("Content-Type: application/atom+xml;type=entry;charset=utf-8"); client.print("Authorization: "); client.println(sas); client.println(); client.print("{ Temperature: "); client.print(t); client.println(" }"); client.println(); // note the time that the connection was made: delay(10000); } else { // if you couldn't make a connection: Serial.println("connection failed"); delay(1000000); } }
  5. Hi, I tried to use sslConnect to communicate with Azure Event Hub. Host for endpoint is stepanb-eh.servicebus.windows.net and I can't connect. If I use same code with another server for example www.google.com I can connect. Only difference I see is length of URL. Any hints? Hardware: CC3200 Lanchpad with latest firmware Stepan
