Mbed Sockets example - Can be used with Ethernet, WiFi or any NetworkInterface

mbed_sockets-example

This example shows usage of network-socket API.

The program brings up an underlying network interface and if it's Wifi also scans for access points. It creates a TCPSocket and performs an HTTP transaction targeting the website in the mbed_app.json config.

The example can be configured to use a TLSSocket. This works only on devices that support TRNG.

Requirements

Hardware requirements

The following boards are required:

• A Zest_Core with a network PHY (e.g. ETHERNET on the Zest_Core STM32H753ZI)

Or

• Any Zest_Core with a Zest_Radio_WiFi

Software requirements

mbed_socket-example makes use of the following libraries (automatically imported by mbed deploy or mbed import):

• U-blox NINA-W132 Wi-Fi module driver if used.

This example uses the default network interface configured in the mbed_app.json file. If using WiFi you will need to configure the SSID and password in the mbed_app.json file, and configure the driver to use the correct pins for your board. For example:

    "ZEST_CORE_STM32L4A6RG": {
        "target.components_add": ["nina_w132"],
        "target.network-default-interface-type": "WIFI",
        "nina_w132.provide-default": true,
        "nina_w132.tx": "UART1_TX",
        "nina_w132.rx": "UART1_RX",
        "nina_w132.rst": "DIO2",
        "nina_w132.debug": false
    }

Usage

To clone and deploy the project in one command, use mbed import and skip to the target enabling instructions:

mbed import https://github.com/catie-aq/mbed_socket-example.git mbed_socket-example

Alternatively:

• Clone to "mbed_socket-example" and enter it:

  git clone https://github.com/catie-aq/mbed_sockets-example.git mbed_sockets-example
  cd mbed_sockets-example

• Deploy software requirements with:

  mbed deploy

Enable the custom target:

cp zest-core-stm32h753zi/custom_targets.json .

Compile the project:

mbed compile

Program the target device with a Segger J-Link debug probe and sixtron_flash tool:

sixtron_flash stm32h753zi BUILD/ZEST_CORE_STM32H753ZI/GCC_ARM/mbed_sockets-example.elf

Debug on the target device with the probe and Segger Ozone software.
