Ubidots example for WizFi310
Dependencies: NetworkSocketAPI WizFi310Interface mbed
Prerequisite
This example is for sending data to Ubidots(Server).
WIZwiki-W7500 and WizFi310 Shield act as TCP client mode.
To implement this function, you need a Platform board and Wi-Fi board. Below are what we used.
- WIZwiki-W7500 from WIZnet (Platform board)
- WizFi310 from WIZnet (Wi-Fi board)
- ETC: PGM5537(CDS sensor) + 10k resistor
Hardware Configuration
WIZwiki-W7500 Pin map
- D0 is for RXD, D1 is for TXD
- D6 is for CTS, D7 is for RTS
- D9 is for RESET
WizFi310 Pin map
- J1 is for RXD, J3 is for TXD
- SW6-1 is connected to D6 for RTS, SW6-2 is connected to D7 for CTS
- SW5-3 is connected to D9 for RESET

Caution
This example requires "Variable ID" and "TOKEN value" that can be obtained by signning up to the Ubidots. //
