I'm playing with the example sketchs using an Uno board and 1.01 and was looking at endsWith to read a string.
But the example doesn't work for me.
startsWith seems OK though.
Can anyone else confirm?
I get the following results regardless of whether the sensor ends with 0.
HTTP/1.1 200 OK
Server's using http version 1.1
Got an OK from the server
sensor = 10. This reading is not divisible by ten
String startsWith() and endsWith():
HTTP/1.1 200 OK
Server's using http version 1.1
Got an OK from the server
sensor = 28. This reading is not divisible by ten
String startsWith() and endsWith():
HTTP/1.1 200 OK
Server's using http version 1.1
Got an OK from the server
sensor = 4. This reading is not divisible by ten
String startsWith() and endsWith():
HTTP/1.1 200 OK
Server's using http version 1.1
Got an OK from the server
sensor = 0. This reading is not divisible by ten
The actual code from the demo.
Can anyone else confirm if I'm going mad.
