3.2 Publish and Monitor MQTT message on the cloud
Step 0: Make sure the AP under test is connected to the internet using other Wi-Fi enabled
devices. Assume the SSID, password and security type of the AP is MySSID, MyPassword,
wpa2.
Step 1: Connect the AW-CU427-USB to the system (refer to 2. Hardware Setup ) and turn off the
wireless devices near the AW-CU427-USB (except for the device under test). Turn on the Wi-Fi
module of the AW-CU427-USB using
AT+WIFI_On
Step 2: Check if AW-CU427-USB is in station mode using AT+WIFI_GetMode
Step 3: Set and store information of the AP using AT+WIFI_SetAP=
MySSID,MyPassword,wpa2
AT+WIFI_SetAP = SSID , password,security type
SSID : SSID of AP (case sensitive)
password : password for AP (case sensitive)
security type : OPEN | WEP | WPA | WPA2
Step 4: Connect to the AP: AT+WIFI_Connect
Step 5 : Define and store Thing-specific configuration using AT+THING_Set command
AT+THING_Set=client ID,endpoint,client certificate,client private key
client ID:
Thing name(Client ID)
endpoint: AWS IoT endpoint URL
client certificate: Certificate for this Thing (downloaded in 3.1 step 3)
client private key: Private key for this Thing (downloaded in 3.1 step 3)
You should create command as format below:
AT+THING_Set=98c6, a25giitjes2mei-ats.iot.ap-northeast-1.amazonaws.com, -----BEGIN
CERTIFICATE-----\
n…base64 data…\n-----END CERTIFICATE-----\n,
-----BEGIN RSA
PRIVATE KEY-----\
n…base64 data…\n-----END RSA PRIVATE KEY-----\n
Note: a25giitjes2mei is just an example endpoint, your endpoint URL should replace it
Step 6: Connect the client to MQTT broker: AT+MQTT_Connect .
Step 7: Subscribe to and save MQTT topic using AT+MQTT_Subscribe=iotdemo/1,0
Step 8: Publish to MQTT topic using AT+MQTT_Publish=iotdemo/1, hello, 0
