[alejandr84]

Hi there, please someone to help me.

Im trying to upload my data from ESP32, Arduino IDE, serial monitor. My data is an array like this:

1 0 21
11 0 19
13 0 21
29 0 43
18 0 25
17 0 22
18 0 22
21 0 23
41 0 43
27 0 26
24 0 22

But, in Thingspeak I don get anything, it create a grafhic, but I just need the data as a table, to analyse it in Matlab.

Please some one can help me, attached my code, maybe is too easy but really can not see.

Your mistake was with the Client.print parameter, I suppose.
