ESP8266: HTTP GET results in 400 Bad Request

-

hi,

i trying obrain data pastebin.com/raw/1nmekaux. using esp8266 connected arduino via softwareserial bound rate of 9600.

every time try make request 400 bad request.

this doing:

code: [select]

at+cipmux=0


ok
at+cipmode=0


ok
at+cwjap="wifi","wifi"

wifi disconnect
wifi connected
wifi got ip

ok
at+cipstart="tcp","pastebin.com",80

connect

ok
at+cipsend=204


ok
>

busy s...

recv 204 bytes

send ok

[/code]

code: [select]

get /raw/1nmekaux http/1.1\r\n
host: pastebin.com\r\n
connection: close\r\n
accept-charset: iso-8859-1,utf-8;q=0.7,*;q=0.7\r\n
cache-control: no-cache\r\n
accept-language: de,en;q=0.7,en-us;q=0.3\r\n
\r\n

a question, when send request packet esp8266, exact c statements?

this expect:
code: [select]

serial.print("get /raw/1nmekaux http/1.1\r\n"); //28
serial.print("host: pastebin.com\r\n"); //20
serial.print("connection: close\r\n"); //19
serial.print("accept-charset: iso-8859-1,utf-8;q=0.7,*;q=0.7\r\n"); //48
serial.print("cache-control: no-cache\r\n"); //25
serial.print("accept-language: de,en;q=0.7,en-us;q=0.3\r\n"); //42
serial.print("\r\n"); //2


i count 184 characters, not 204?

chuck?

hi, sorry, new , unsure lot of things, need clarification. haven't found information explains how , why things work, "do this, that" i following guide ( arduino-thermistor-temperature-sensor-tutorial ) connect thermistor arduino uno. here temperature sensor information: temp. sensor 2000r +-1% to92 part.no.:   kty81-210 name:   temp. sensor 2000r +-1% to92 description:   2.5mm, 1980...2020ohm, -55...+150°c and here sensor's data-sheet: sensor data-sheet i have connected same way in guide. works , values being serial printed. what don't understand: 1. thermistor's , resistor's ohm value should equal, correct? in case 2000 ohm? 2. thermistor has ptc, i'm guessing have invert math or use ntc thermistor instead correct values? (currently resistance goes temperature goes down) 3. understand code uses steinhart-hart math logic convert resistor value temperature value, need a, b , c coefficients of thermis...
