How can I receive and display JSON data sent from a local server? I am talking about a script in lua fired on ESP8266 version 01. Ultimately I want to display this data on a 2x16 lcd connected to the ESP8266 via i2c.

I have such a listing in lua: Code: C / C++Log in, to see the code which when run on the ESP throws up: {lowVersion:1, highVersion:3} and it's OK, it's valid JSON data. Then I try: Code: C / C++Log in, to see the code throws out: test.lua:10: Expected value but found invalid token at character 1 How to display a single value lowVersion or highVersion I want to save them as variables.

I have such a listing in lua:

Code: C / C++
Log in, to see the code

which when run on the ESP throws up:

{"lowVersion":1, "highVersion":3}

and it's OK, it's valid JSON data.

Then I try:

Code: C / C++
Log in, to see the code

throws out:

test.lua:10: Expected value but found invalid token at character 1

How to display a single value "lowVersion" or "highVersion"
I want to save them as variables.
