Problem sending data from ThignSpeak to Simulink

Hello!
I have a channel in ThingSpeak. Field number 4: Temperature, with some data. But, when I try to read that data in Simulink, I only receive 0... What could be happening?

Are you sure the R Pi is connected to the WiFi? What is the value at the status output?

Hello Vinicio,
I just tried to read from your thingspeak channel and got the data. I ran the model in “Monitor & Tune” mode and could see the data. Please check the attachment.
To confirm the issue at your end please share the output of status port and the ‘Diagnostic viewer’
Thanks,
Reeno Joseph

I´m trying with another blocks, and with this one, it is working. But, I need send this to run over a Raspberry Pi, and I can not use the ThingSpeak Input block. But, here is obviusly that the problem is in the Raspberry Pi ThingSpeakRead block...

On the other hand, if I use Raspberry Pi ThingSpeak Write block, it is sending all the time a 0. When manually I change that value with a 20, the system write a 20... But, the value of the constant in the left side is just like it doesn´t exists.
