Secure Communication shows how to use mbed TLS together with the Network Component to secure your communication channels.Troubleshooting a Network Application shows best practice when debugging general network/connection issues.Creating a Network Application explains the necessary steps to develop a network project from scratch.This user's guide contains the following chapters: ![]() Note A compatibility mode is available that enables you to use the old v6 API with only minor modifications in a v7 project. The following table shows the differences in Network component availability: MDK Middleware is available to all users of MDK-Professional and MDK-Plus. Unique identifiers are required for proper network operation.Ī list of implemented RFCs is also available. The Release variant omits this diagnostic information.įor mass production, the Runtime Configuration option can be used to assign individual network addresses to every device that is produced. The Network CORE is available in a Debug variant with extensive diagnostic messages. Some devices may support transparent mode at a higher level, such as TCP - this will not work with the Network component. This mode allows to send the Ethernet frames assembled by the Network component transparently through the WiFi chip/module. If you intend to use the MDK-Middleware Network component with a WiFi chip/module, make sure that its WiFi driver supports the bypass mode (currently only available for the Qualcomm QCA400x). This means that payload data is sent via a serial interface to the WiFi chip/module and the Ethernet frames are assembled inside. Note Usually, WiFi chips and modules have their own networking stack incorporated. For WiFi interface a WiFi module is required.PPP or SLIP interfaces use a USART and a Modem.For Ethernet an Ethernet MAC and an Ethernet PHY is required.WiFi Interface is often used for wireless networking of local networks or to connect to the Internet of Things.Ī driver provides the interface to the microcontroller peripherals or external components (for example an external PHY chip or WiFi module).The PPP Interface connects two network devices directly and provides authentication.The SLIP Interface implements the Internet Protocol over a serial connection.The serial connection supports two different protocols:.It can utilize different media as means of transmission. Ethernet Interface is widely used for connecting local area networks (LAN).The physical interface can be either Ethernet, WiFi or a serial connection. The BSD Socket API is a programming interface, which implements a standard Berkeley Socket communication interface (using TCP and UDP sockets for communication).With UDP you can multicast a datagram to a group of devices. Data streaming or time-critical applications commonly use UDP. UDP is a transaction-oriented and stateless protocol.This means that packets delivered using TCP are error-checked and delivered in the right order. TCP is a connection-oriented, reliable full-duplex protocol.The Network Component supports these sockets: ![]() Using the ARM mbed TLS component, you can enable secure communication and send e-mails using publicly available services like Gmail, Yahoo, etc.Īll services rely on a network socket for communication. The SMTP Client helps you to send out for example status updates or alerts via e-mail to freely configurable e-mail addresses.The SNTP Client synchronizes clocks and enables a device to get an accurate time signal over the data network.It makes use of a freely configurable name server. The DNS Client resolves domain names like to the respective IP address.The SNMP Agent helps to report vital information of a device to the network manager. Devices are often monitored using the Simple Network Management Protocol (SNMP).The Telnet Server realizes a simple Command Line Interface ( CLI) over an IP network.FTP provides full file access including sub-directories, log-in and a set of manipulation commands. TFTP supports only file upload and download and is typically used for boot-loading remote devices in a closed LAN. FTP server/ client and TFTP server/ client are used for file transfer.Using the ARM mbed TLS component, you can enable secure communication for both web servers using HTTPS. Web resource files are accessed either via the File System (for component Web Server) or are directly stored in ROM (for component Web Server Compact). The HTTP Server supports static and dynamic page content using scripting, AJAX and SOAP technologies. ![]() The various services provide program templates for common networking tasks:
