IBM WATSON connection using a71ch - axI2CTerm: not implemented and Watson IoT Platform: rc=-15

[kuldip_kanzariy]

We are trying to connect to the IBM WATSON IoT platform using the below-mentioned code :

source: https://github.com/ibm-watson-iot/iot-nxpimxa71ch-c

we followed the steps mentioned in the above code.

1. We are able to compile the code and generate the sample Binaries in the mentioned folder (/opt/iotnxpimxclient/bin)

2. Using generated out facts we are able to create certificates also.

3. We have registered a device, uploaded the certificates and changed the connection policy.

4. While using sample binary with certificates to connect with IBM Iot platform ,we are getting an error as mentioned below:

Initialize logging. LogFile:./iotfclient.log LogLevel:3
I2CInit: opening /dev/i2c-0
I2C driver: PEC flag cleared
I2C driver supports plain i2c-level commands.
I2C driver supports Read Block.
axI2CTerm: not implemented.
