Hello,
I tried the realization of a circuit that worked as an MQTT client: in the simulation in Flowcode it works correctly (updating data in Thingspeak while in the real circuit it does not (I immediately exclude that it is a hardware problem as the circuit works correctly with other configurations of use of ESP8266). Furthermore, the same operating error is obtained by simulating in Proteus; until the connection to the remote computer everything is ok then the error occurs following the sending of the command AT + CIPSEND = 0,103 to ESP8266 obtaining a "no tail" response. I'm reasonably sure there is a problem in one of the three components used.
In attachments photo and flowchart ( i have replaced key Thingspeak with "X").
Thanks

Many thanks for letting us know and sorry for the delay.

Hopefully now fixed, At least it's now working well for me here.

Let us know how you get on.
