+# ME310G1 / Charlie official communication library for Arduino
+
+Code library for Arduino projects using ME310G1 devices (for example, on [Charlie Board](https://github.com/telit/arduino-charlie) )
+
+
+
+## Contents
+
+This Library will provide a set of APIs wrapping the AT commands to simplify the interaction with the ME310G1 device.
+
+### Classes
+
+The library provides the following classes:
+
+ - **ME310** :  _main class providing all the functionalities, the only needed for users' code_
+ - **Parser** : _internal helper classes to simplify the AT command responses parsing_
+ - **PathParsing** : _internal helper class to parse the file paths on the device_
+ - **ATCommandDataParsing** : _internal class used to call Parser_
+
+
+### Examples
+
+The following examples are available:
+
+ - **[AGNSS_example](examples/AGNSS_example/AGNSS_example.ino)** : _Simple example that shows how to configure the AGNSS functionality_
+ - **[Bosch_sensor_example](examples/Bosch_sensor_example/Bosch_sensor_example.ino)** : _Shows how to retrieve info from the onboard Bosch BMA400 accelerometer_
+ - **[CheckModule](examples/CheckModule/CheckModule.ino)** : _Turns the modem on and checks if it responsive_
+ - **[CLIP_example](examples/CLIP_example/CLIP_example.ino)** : _Shows how to use Calling Line Identifier protocol_
+ - **[FTP_example](examples/FTP_example/FTP_example.ino)** : _Connects to an FTP server and performs basic operations_
+ - **[GNSS_example](examples/GNSS_example/GNSS_example.ino)** : _Simple GNSS example, it enables the GNSS receiver and provides raw location data_
+ - **[LWM2M_example](examples/LWM2M_example/)** : _uses LwM2M protocol and the accelerometer to send data to the OneEdge portal_
+   - **[LWM2M_example_2G](examples/LWM2M_example/LWM2M_example_2G/LWM2M_example_2G.ino)** : _example with 2G network_
+   - **[LWM2M_example_4G](examples/LWM2M_example/LWM2M_example_4G/LWM2M_example_4G.ino)** : _example with 4G network_
+ - **[M2M_example](examples/M2M_example/M2M_example.ino)** : _Communicates with the modem using the M2M commands to manage the filesystem_
+ - **[ME310_AT_Test](examples/ME310_AT_Test/ME310_AT_Test.ino)** : _Communicates with the modem and provides info about it (ICCID, IMEI etc.)_
+ - **[MQTT_example](examples/MQTT_example/MQTT_example.ino)** : _Communicate with a MQTT broker_
+ - **[Ping_example](examples/Ping_example/Ping_example.ino)** : _Simple example that enables the connectivity and pings a server_
+ - **[Socket_example](examples/Socket_example/Socket_example.ino)** : _Enables connectivity and uses a TCP socket example communicating with a demo server_
+ - **[TransparentBridge](examples/TransparentBridge/TransparentBridge.ino)** : _Enable the modem and creates a bridge between Arduino serial and modem AT interface, allowing user to send AT commands manually_
+
+
+## Support
+
+If you need support, please open a ticket to our technical support by sending an email to:
+
+ - [email protected] if you are in the Americas region
+ - [email protected] if you are in EMEA region
+ - [email protected] if you are in APAC
+
+ providing the following information:
+
+ - module type
+ - answer to the commands (you can use the TrasparentBridge example to communicate with the modem)
+   - AT#SWPKGV
+   - AT+CPIN?
+   - AT+CCID
+   - AT+CGSN
+   - AT+CGDCONT?
+
+and add [Charlie][AppZone] in the e-mail object, and in the e-mail body refer to the opened issue on github.

     In this example sketch, it is shown how to use AGNSS management, using ME310 library.\n
     AGNSS is enable, GNSS configuration, GNSS controller power management, GNSS nmea configuration functions are shown.\n
     GPS positions are acquired and response is printed.
+	NOTE:\n
+	For the sketch to work correctly, GNSS should be tested in open sky conditions to allow a fix. The fix may take a few minutes.
