Running the IoTeX SDK in Linux

Get the source code

git clone https://github.com/iotexproject/arduino-sdk
cd arduino-sdk

Building the library

Requires cmake 3.1.0 or higher.

Refer to https://cmake.org/install/ for instrutions on how to install cmake.

mkdir build && cd build
cmake ..
make

If successful, build files are placed in the build directory.

Building and running the tests

Building the tests

mkdir build && cd build
cmake -DUNIT_TEST=ON ..
make

Unit tests build files are placed in build/tests.

Running the tests

cd build
./tests/iotex_unit_tests

Using the library in your application

Include the IoTeX-Client main header in your program as below:

#include <IoTeXClient.h>

Create the Connection object, passing the connection details:

const char ip[] = "gateway.iotexlab.io";
const char baseUrl[] = "iotexapi.APIService";
const int port = 10000;
Connection<Api> connection(ip, port, baseUrl);

Now you are ready to call any of the API methods.

You can find examples of most of the library methods under the examples directory.

Debug logs

Debug logs are disabled by default. They can be enabled at runtime or at compile time.

Follow the instructions below in order to enable them and set the log level.

The log level can be set per module, and also globally. A log statement is printed if it's level is higher than the log level configured for it's module, and higher than the global log level.

The library prints logs to stdout using printf().

Setting debug log level at compile time

This can be done by setting the LOG_LEVEL cmake variable before building. Eg:

cmake -DUNIT_TEST=ON -DLOG_LEVEL=DEBUG ..

The possible values for LOG_LEVEL are:

• NONE (default)

• ERROR

• WARNING

• INFO

• DEBUG

• TRACE

Setting debug log level at run time

The log level can also be set at runtime using the IotexHelpers global object.

Setting per module log level

You can set the log level for a specific module. The existent log modules are:

• "GENERAL"

• "HTTP"

• "CONTRACT"

Simply call the following method on the IotexHelpers global object: void setModuleLogLevel(const std::string& module, IotexLogLevel level)

Eg. This will set the HTTP log level to DEBUG: IotexHelpers.setModuleLogLevel("HTTP", IotexLogLevel::DEBUG);

Setting the log level globally

You can also set the log level globally for all modules.

Simply call the following method on the IotexHelpers global object: void setGlobalLogLevel(IotexLogLevel level)

Eg. This will set the log level globally to DEBUG: IotexHelpers.setGlobalLogLevel(IotexLogLevel::DEBUG);
