0.9.3

• Removal of call to function init within ArduinoIoTCloudLPWAN::begin since init is implemented empty within the LoRa connection handler (48e8a1e)
• Further cleaning up and refactoring.

0.9.2

• Removing unused parameter Client & of ArduinoIoTCloud::reconnect()
• Register a function for retrieving a global timestamp with ArduinoCloudThing (necessary to break hidden dependency to RTCZero - see here).
• Bugfix: The TCP load balancer of the Arduino IoT Cloud terminates a TCP connnection after 350 seconds. Unfortunately this termination is only detected after transmitting the next data set to the Arduino IoT Cloud. This has the unfortunate side effect that the data set sent to the cloud is lost. This change buffers every transmission to the server and requests a retransmission in case of loosing the connection. Note: This can only happen if the keep-alive interval is set to a value > 350 seconds.

0.9.1

• Removal of update previously marked as deprecated
• Removal of unused struct mqttConnectionOptions
• Refactoring of time provisioning code within a single class TimeService

0.9.0

• This release adds support for the MKRWAN LoRa board to be used with the Arduino IoT Cloud.

0.8.3

Release 0.8.3

0.8.2

• add cloud blink example for mkr nb 1500

0.8.1

• Adding missing dependencies ArduinoECCX08,RTCZero to depends statement within library.properties.

0.8.0

BREAKING CHANGES:

The code which handles WiFi and GSM connections as well as the code which handles the debug and status messages have until now been a part of the ArduinoIoTCloud library. This is no longer the case. In order to simplify ArduinoIoTCloud and allow the easy addition of new connection types the code responsible for connection handling has been put into a separate Arduino library Arduino_ConnectionHandler. Similiarly the code responsible for debug and status messages has been put into a separate Arduino library Arduino_DebugUtils.

Unfortunately those changes break compatibility with already existing sketches which is why you need to make the following adjustments to get your code to compile again:

• Modify thingProperties.h

MKR1000/MKR WiFi 1010

-#include <GSMConnectionManager.h>
+#include <Arduino_ConnectionHandler.h>
...
-ConnectionManager * ArduinoIoTPreferredConnection = new WiFiConnectionManager(SSID, PASSWORD);
+WiFiConnectionHandler ArduinoIoTPreferredConnection(SSID, PASSWORD);

MKR GSM 1400

-#include <WiFiConnectionManager.h>
+#include <Arduino_ConnectionHandler.h>
...
-ConnectionManager * ArduinoIoTPreferredConnection = new GSMConnectionManager(SECRET_PIN, SECRET_APN, SECRET_LOGIN, SECRET_PASS);
+GSMConnectionHandler ArduinoIoTPreferredConnection(SECRET_PIN, SECRET_APN, SECRET_LOGIN, SECRET_PASS);

Also there is no longer a need for the cloud specific Arduino library ArduinoIoTCloudBearSSL. It is replaced with the general purpose Arduino port of BearSSL ArduinoBearSSL.

If you are compiling your sketches on the Arduino Create platform the new libraries Arduino_ConnectionHandler, Arduino_DebugUtils and ArduinoBearSSL have already been installed for you. If you are working on your PC those libraries need to be installed, e.g. via the library manager.

0.7.0

• add nano iot connection support [WIP]

0.6.1

• Multi-Value-Property sketch has been added to Travis CI build
• arduino-cli is used for CI build instead of Arduino IDE CLI
• Travis build is executed with stronger compile time checks (arduino-cli compile --warnings all)
• Problems uncovered by stronger compile time checks have been fixed
• Dependencies for CI build are fetched directly from github instead of a download via library manager to reduce wait time when fixing issues in dependent libraries
• Reduction of the available signatures for update
