3 Getting Started with ATWINC1500 IoT Examples
This chapter introduces ATWINC1500 IoT examples and describes how to run an example on the SAM D21
board.
3.1 Organization of ATWINC1500 IoT Examples
All these examples are included in the ASF package and there are various IoT examples using Wi-Fi module.
3.1.1 Basic Examples
These examples describe basic Wi-
Fi operation in ‘how-to’ manner:

How to read chip ID (to identify ATWINC1500 H/W revision)

How to set debug message level

How to get MAC address of the Wi-Fi module

How to start Wi-Fi in specific operation mode, such as:
–
STA Mode (Station mode), AP mode (Access Point mode), and P2P mode (client mode)

How to switch mode among STA, AP, and P2P modes during the runtime

How to scan APs nearby

How to set deep sleep mode

How to connect to secure Wi-Fi with using WEP/WPA/WPA2 security

How to connect to enterprise security network

How to connect to security WPS

How to set packet monitoring

How to get RF signal status by reading RSSI value

How to set AP provision

How to set HTTP provision
3.1.2 Protocol Examples
After basic code examples, the user may be interested in how to send and receive network packets. Here are
protocol examples that can be extended for IoT application.

UDP protocol example

TCP protocol example

NTP Time client
– retrieve network time for IoT application

MQTT protocol client example

Send email
– send an email from SMTP server

Location client
– get the current location of the network provider using HTTP
3.1.3 Advanced Examples
These examples demonstrate more complex functions like:

Growl client
– demonstrates using RESTful API over SSL (essential for IoT application)

MQTT Chat client
– demonstrate how to send and receive IoT information using MQTT protocol

Weather client
– get the current weather information of the network provider and utilize the IO1 sensor
device

Wi-Fi serial - useful for chatting or controlling a remote device

OTA Firmware Upgrade
– ATWINC1500 Firmware upgrade via OTA server

SSL connection - Set up an SSL connection
