Dear Wiznet support,
I am currently attempting to use your WizFi310 EVB device to communicate and publish data to thingsspeak using the MQTT AT commands.
I have easily achieved
-
Connection to Wi-Fi
-
MQTT connection with the thingspeak channel - MQTT indicates [OK] - so everything is working .
My next step is to publish to a channel/field. I would appreciate if you could help me with the correct syntax for the MQTTpub command please.
I have verified via MQTT.fx that I can publish data to think speak using the following syntax.
Here is a log example if the message successfully published to the thingspeak channel a few minutes ago
sucessfully published message field1=100&field2=160&status=sent to topic channels/254968/publish/XXZZ11SHLHX5EXX (QoS 0, Retained: false)
How do I use AT+MQTTPUB to send the data to the channel fields on thingspeak? what is the correct way to form the command text?
many thanks for your assistance
all the best
Pete
