ESP 8266,Arduino and Thingspeak
i doing project upload sensor value thinkspeak,everthing ok ,but thingspeak webpage not show value??

when code not match comment, comment looks stupid. why trying software serial on hardware serial pins?
code: [select]
serial.begin(9600);
why trying software serial on hardware serial pins while using them hardware serial?
code: [select]
getstr += string(tempstr);
wrapping string in string sure looks dumb.

void loop() {
char buffer[10];
// read sensor values
float t = mlx.readobjecttempc();

i see hired drunken monkey type code you. not idea. every { goes on new line. tools + auto format function clear piss-poor indenting.
