+## Description
+
+The test-cloud-app and telemetry-cloud-app are examples of an agl-cloudproxy-service client.
+They are used to demonstrate the possibilities of the cloudproxy service.
+
+## Applications
+
+* test-cloud-app: Simple application demonstrating the following possibilities:
+ * Sending the messages to cloud over cloud proxy server
+ * Receiving confirmations from cloud on the sent messages
+ * Receiving messages from cloud
+
+
+* telemetry-cloud-app: Application which sends the GPS coordinates to the cloud
+ * Sending of the messages with telemetry to the cloud
+ * Receiving of the messages from the cloud
+
+Applications use CloudProxy client as high level interface for the messages sending and receiving
+
+## CloudProxy client
+
+CloudProxy client hides the communication with CloudProxy server. It incupsulates the following actions
+
+* Connection to **cloudporxy** over wsj1 websocket
+* Subscription to the event
+* Event loop handling
+
+**Note:** At the moment only two event types are supported
+1. Event_SendMessageConfirmation
+2. Event_ReceivedMessage
+
+### Usage of a Cloudproxy client:
+
+* Include the appropriate header to appliciation
+
+ ```
+ #include "cloudproxy-client/cloudproxyclient.h"
+ ```
+
+* Initialization of the CloudProxy client inside the application:
+
+```
+CloudProxyClient* g_cloudproxyclient{nullptr};
+
+g_cloudproxyclient = new CloudProxyClient();
+g_cloudproxyclient->init(port, token.c_str());
+
+```
+
+### Message handling from/to the CloudProxy server:
+
+
+* Subsription to the Event_SendMessageConfirmation
+
+
+
+```
+g_cloudproxyclient->set_event_handler(CloudProxyClient::Event_SendMessageConfirmation, [](json_object* object){
+ json_object *j_result;
+ if(!json_object_object_get_ex(object, "result", &j_result))
+ {
+ qDebug("Can't read confirmation result");
+ return;
+ }
+
+ qDebug("Confirmation result %d", (int)json_object_get_boolean(j_result));
+ });
+
+ ```
+
+
+
+* Subsription to the Event_SendMessageConfirmation
+
+```
+g_cloudproxyclient->set_event_handler(CloudProxyClient::Event_ReceivedMessage, [](json_object* object)
+ json_object *event_data;
+ const char* data_str{nullptr};
+ if(!json_object_object_get_ex(object, "data", &event_data) ||
+ data_str = json_object_get_string(event_data)) == nullptr)
+ {
+ qDebug("Can't read event data");
+ return;
+ }
+
+ qDebug("Received data: %s", data_str);
+ });
+ ```
+
+
+* Message sending:
+
+
+```
+qDebug() << "sendMessage result: " << g_cloudproxyclient->sendMessage("{\"app_key\": \"app_value1111\"}");
+```
