[phongvucba]

people help me!
I looked on google and could not find any information about this.
  Samsung TV can be controlled via TCP (or udp, http)?
If anyone knows, please help me. I know you very well.!
Thank all!

Thank you very much!
I have also read, but do not really understand!
You can write a simple code on LM3 to select the HDMI sources?

Hi,

Here is a script i created a while ago for controlling Samsung.

I never tested this as i have Sony TV (;

Could be i'ts not working but you have a 99% solution that might need some small adjustments in the send (encoded) dataset. 
Check documentation i send as URL's in previous post to change it / correct it to the documented format when script does not work like expected.

I have no time to do it for you ..

Code:

require('encdec')

tvip = "100.0.0.123"
myip = "100.0.0.112"
mymac = "00-0c-29-3e-b1-4f"
appstring = "iphone.iapp.samsung"
tvappstring = "iphone.UE55C8000.iapp.samsung"
remotename = "LUA Samsung Remote"
ipencoded = encdec.base64enc(myip)
macencoded = encdec.base64enc(mymac)

-- TCP Send Samsung TV
function sendKey(ip, skey)
    host, port = tvip, 55000
 socket = require("socket")
 client = socket.tcp()
 client:settimeout(1)
 client:connect(host, port)
 messagepart1 = string.char(0x64) .. string.char(0x00) .. string.char(string.len(ipencoded)) .. string.char(0x00) .. ipencoded .. string.char(string.len(macencoded)) .. string.char(0x00) .. macencoded .. string.char(string.len(encdec.base64enc(remotename))) .. string.char(0x00) .. encdec.base64enc(remotename)
    part1 = string.char(0x00) .. string.char(string.len(appstring)) .. string.char(0x00) .. appstring .. string.char(string.len(messagepart1)) .. string.char(0x00) .. messagepart1
 client:send(part1)
 --log(lmcore.strtohex(part1))
 result1 = client:receive()
 messagepart2 = string.char(0xc8) .. string.char(0x00)
 part2 = string.char(0x00) .. string.char(string.len(appstring)) .. string.char(0x00) .. appstring .. string.char(string.len(messagepart2)) .. string.char(0x00) .. messagepart2
    client:send(part2)
 --log(lmcore.strtohex(part2))
 result2 = client:receive()
 local messagepart3 = string.char(0x00) .. string.char(0x00) .. string.char(0x00) .. string.char(string.len(encdec.base64enc(skey))) .. string.char(0x00) .. encdec.base64enc(skey)
    local part3 = string.char(0x00) .. string.char(string.len(appstring)) .. string.char(0x00) .. appstring .. string.char(string.len(messagepart3)) .. string.char(0x00) .. messagepart3
 client:send(part3)
 log(lmcore.strtohex(part3))
 result3 = client:receive()
 client:close()
 return result1, result2, result3
end

--Now send the keys as you like, e.g.,
result1, result2, result3 = sendKey(tvip, "KEY_TOOLS")
log(result1, result2, result3)
os.sleep(1)
result1, result2, result3 = sendKey(tvip, "KEY_RIGHT")
log(result1, result2, result3)
os.sleep(1)
result1, result2, result3 = sendKey(tvip, "KEY_DOWN")
log(result1, result2, result3)
os.sleep(1)
result1, result2, result3 = sendKey(tvip, "KEY_RIGHT")
log(result1, result2, result3)

===============
Thank so much..Pro.! But Dear friends!
appstring = "iphone.iapp.samsung" --What is it?
tvappstring = "iphone.UE55C8000.iapp.samsung" --What is it?

Hi,

appstring = "iphone.iapp.samsung"    --What is it?
Answer: This is just a identifier for the tv, now the tv thinks it's
connected to a iPhone (: Don't change it. 

tvappstring = "iphone.UE55C8000.iapp.samsung"  --What is it?
Answer: This holds your tv model now you control a 55 inch C8000 model.
If you have different model you need to change it.

Hi Erwin,

is this script working for newer Samsung TV 2015- ?
I treid it but I get only "nils" as return values.

Code:

Event for TV Tools-Taste (8/0/0) 02.10.2016 20:52:32
* arg: 1
 * nil
* arg: 2
 * nil
* arg: 3
 * nil
Event for TV Tools-Taste (8/0/0) 02.10.2016 20:52:32
* string: 0013006970686F6E652E696170702E73616D73756E6711000000000C005330565A5831525054307854

I think it's a authentication problem, or?
