Mr Yikai! Have you read my post?

0 YiKai Chen over 8 years ago in reply to Antonio Racchio

Guru 735695 points

Yes, I read it. Since you have added the device ID to IBM IOT service, you can use it instead of QuickStart to test it.

IoT Platform, I add a device in this Platform. Now?

0 YiKai Chen over 8 years ago in reply to Antonio Racchio

Guru 735695 points

If you want to use IBM's cloud service with a registered device, change 'Org ID' and provide an 'Auth Token', which acts as a 'password“

0 Antonio Racchio over 8 years ago in reply to YiKai Chen

Expert 2280 points

Ok, I modify the token, but the ORG id how can i change?

0 YiKai Chen over 8 years ago in reply to Antonio Racchio

You are still connecting to ibm Quickstart. What do you input in MQTT settings page of CC26xx-web-demo web?

0 Antonio Racchio over 8 years ago in reply to YiKai Chen

Expert 2280 points

In the mqtt-client code?

0 Antonio Racchio over 8 years ago in reply to YiKai Chen

Expert 2280 points

I should change this:

defined: #define QUICKSTART "quickstart"
changed: if(strncasecmp(conf->org_id, QUICKSTART, strlen(conf->org_id)) != 0) {

If yes, What i put on this space?

0 YiKai Chen over 8 years ago in reply to Antonio Racchio

Guru 735695 points

You should input Org ID and token from MQTT settings page of CC26xx-web-demo web.

0 YiKai Chen over 8 years ago in reply to Antonio Racchio

Your Org ID and Auth Token look incorrect. You have to follow the steps in www.ibm.com/.../index.html to generate Org ID and get Auth Token.
