I am using ioT long range Wireless One channel counter for counting the number of parcel received. I am sending these values to esp32 serially. To access these values remotely I am publishing the valueto ThingSpeak using Thingspeak MQTT link. But I am getting guru Meditation exception while publishing the values to thing speak.kindly help me with it
You should also be able to update the value of a ThingSpeak field using the REST API.
The MQTT connection is intended to be very lightweight, thus it does not provide much feedback on the reasons it may not accept your connection or publish request. If you still want to try using the MQTT method, I would suggest you review the troubleshooting tips and then consider posting on the ThingSpeak Community Forum.
