Examples
The examples below are all done using a EB091 board as the host
The EB069 ESP8266 Wifi E-block is connected to PORTD 0-7 with the patch setting set to B.
The EB005 LCD E-block is connected to PORTB 0-7 with the patch setting set to Default.
Other host boards are compatible with the examples, simply change the target chip and component connection properties.
Firmware Test
This example collects the firmware version from the ESP8266 module and displays it on an LCD. Tested working with firmware version 00150900.
Wireless Scanner
This example scans for wireless networks in range and prints the network IDs to the LCD along with the signal strength and security type.
Creating An Access Point
This example creates an access point you can connect your phone or laptop to named Flowcode_ESP8266. The password to connect to the access point is flowcode6.
Note this example simply creates an access point, no data is transferred.
Joining An Access Point
This example joins an existing access point. The network ID and Password must be altered to match your local WIFI network settings.
Note this example simply joins an access point, no data is transferred.
TCP Client
This example joins an existing access point. The network ID and Password must be altered to match your local WIFI network settings.
Once joined to the network the example connects to the MatrixTSL website and requests a file which is printed out on the LCD.
TCP Server
This example creates an access point you can connect your phone or laptop to named Flowcode_ESP8266. The password to connect to the access point is flowcode6.
Once the access point is created the example shows the server IP address on the LCD. Connecting to the wireless network on your phone or laptop and visiting the IP address shown on the LCD using a web browser allows you to switch LED outputs on and off.
Network Comms
Here are some examples using the Network Communication component linked to the ESP8266 component.
