How to integrate in the AWS IoT C sdk

  1. 1.
    Clone the AWS-IoT-sdk
    1
    git clone https://github.com/aws/aws-iot-device-sdk-embedded-C.git -b v3.0.1
    Copied!
  2. 2.
    Clone this repository inside the external_libs directory
    1
    cd aws-iot-device-sdk-embedded-C/external_libs/
    2
    git clone https://github.com/uniquid/uidagent-c.git
    Copied!
  3. 3.
    Clone the uidcore-c library
    1
    git clone --recurse-submodules https://github.com/uniquid/uidcore-c.git
    Copied!
  4. 4.
    Clone the mbedtls code
    1
    rm mbedTLS/README.txt
    2
    git clone https://github.com/ARMmbed/mbedtls.git mbedTLS -b mbedtls-2.16.1
    Copied!
  5. 5.
    Apply the provided patch, IoT-sdk.patch
    1
    cd ..
    2
    git apply external_libs/uidagent-c/IoT-sdk.patch
    3
    cd samples/linux/subscribe_publish_sample
    4
    make
    Copied!

Run the C device

  1. 1.
    Copy in the "certs" directory the CA certificates chain to authenticate the aws-mqtt-proxy and the uniquid mqtt broker. The file must be named rootCA.crt
    1
    cp ../../../../caChain-xxxxxxxxxxxxxx.crt ../../../certs/rootCA.crt
    Copied!
    Press tab to find the right caChain file.
  2. 2.
    Copy the configuration file (example file) **
    1
    cp ../../../../aws_device_cfg.json aws_device_cfg.json
    Copied!
  3. 3.
    Run the sample
    1
    ./subscribe_publish_sample
    Copied!
** The configuration can also be loaded from AWS_AGENT_CONFIG environment variable
1
export AWS_AGENT_CONFIG=$(cat path-to/aws_device_cfg.json)
Copied!
The device will try to connect to the proxy every 10 seconds, for this reason an error message will be reported until you create an UniquID Contract between the C device and the AWS-IOT-UNIQUID-AUTHORIZER to bind these two components.
Only when both the components will receive the contract from the blockchain, the device will be able to connect.
