uidagent-c

Minimal code implementing an UniquID node. It can be used to add UniquID functionalities to the AWS IoT C sdk

It requires:

• libuidcore-c
• libpthread
• AWS IoT mqtt implementation

how to integrate in the AWS IoT C sdk

• Clone the AWS-IoT-sdk (this has been tested on tag v3.0.1 and master@c11e34a98be):
  git clone https://github.com/aws/aws-iot-device-sdk-embedded-C.git -b v3.0.1
• Clone this repository inside the external_libs directory:
  cd aws-iot-device-sdk-embedded-C/external_libs/
git clone https://github.com/uniquid/uidagent-c.git
• Clone the uidcore-c library
  git clone --recurse-submodules https://github.com/uniquid/uidcore-c.git
• Clone the mbetls code:
  rm mbedTLS/README.txt
git clone https://github.com/ARMmbed/mbedtls.git mbedTLS -b mbedtls-2.16.1
• Apply the provided patch, IoT-sdk.patch
  cd ..
git apply external_libs/uidagent-c/IoT-sdk.patch
• Cd to subscribe_publish_sample example and make
  cd samples/linux/subscribe_publish_sample
make

run the "subscribe_publish_sample"

• 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:
  cp path-to/caChain.crt ../../../certs/rootCA.crt
• Copy the configuration file (here is an example)
  cp path-to/aws_device_cfg.json aws_device_cfg.json
• run the sample
  ./subscribe_publish_sample

** configuration can be loaded also from AWS_AGENT_CONFIG environment variable:
export AWS_AGENT_CONFIG=$(cat path-to/aws_device_cfg.json)
