IoT Foundation Bluemix TI SensorTag CC2650STK

Question

So, I successfully have connected the SensorTag with the BLE SensorTag app on my Android phone and I can use the default Push to Cloud Quickstart setup to send data to IoT Foundation Quickstart. But I keep attempting to to connect to IoT Foundation as a registered device and fail.

My device registration IoT foundation:

Organization ID         abcdef   (<- not my real org on IoT Foundation)
Device Type             sensortag
Device ID               sensortag1
Authentication Method   token
Authentication Token    somecrypticcharacters

This is the BLE SensorTag app on my phone in Cloud Setup:

Cloud Service: IBM IoT Foundation
Username:      use-token-auth
Password:      somecrypticcharacters
Device id:     d:abcdef:sensortag:sensortag1
Broker add.:   abcdef.messaging.internetofthings.ibmcloud.com
Broker Port:   1883
Publish topic: iot-2/evt/sensors/fmt/json

On enabling Push to Cloud, this error gets thrown at me.

"Failed with error code: Attempt to invoke virtual method 'boolean java.lang.String.equals(java.lang.Object)' on a null object reference'

Can any tell me where I'm going wrong here?

Try the following:

• The SensorTag code is available here : https://git.ti.com/sensortag-20-android
• Open IBMIoTCloudProfile class
• line 245, change the connection code from

client.connect(options, new IMqttActionListener() {....

to

client.connect(options,this.context, new IMqttActionListener() {...

• compile and install the updated app.
