Hi, need to controll Epson projector (send PWR On, PWR Off, PWR?) messages For controllinhg Epson, need to send a command for establishing connection (0x450x530x430x2F0x560x0500x2E0x6E0x650x740x100x030x000x000x000x00) and after that send the command for interogating power status (0x500x570x520x3f0x0d) Testing this from Hercules utility, works great When coding in LUA, after sending first command, when trying to send second command I get Connection reset by peer error If sending just first command, I get a proper response, so, no error in connection or command string Here is my code: function QuickApp:onInit() self:debug("onInit") self.ip = self:getVariable("ip") self.port = tonumber(self:getVariable("port")) self.sock = net.TCPSocket() end function QuickApp:parseData(str) while true do if string.find(str, '0x') then i,j = string.find(str, '0x') str = string.sub(str, 1, i - 1) .. self:fromhex(string.sub(str, i + 2, j +2)) .. string.sub(str, j + 3) else return str end end end function QuickApp:fromhex(str) return (str:gsub('..', function(cc) return string.char(tonumber(cc, 16)) end)) end function QuickApp:connect(successCallback) print("connecting:", self.ip, self.port) self.sock:connect(self.ip, self.port, { success = function() self:debug("connected") successCallback() end, error = function(err) self.sock:close() self:debug("connection error connect", err) end, }) end function QuickApp:init(event) --self:connect() self:send("0x450x530x430x2F0x560x0500x2E0x6E0x650x740x100x030x000x000x000x00", true, "0x500x570x520x3f0x0d") end function QuickApp:send(dataToSend, waitForResponse, pwr) self:connect(function() local dataConverted = self:parseData(dataToSend) local pwrConverted = self:parseData(pwr) self.sock:write(dataConverted) fibaro.setTimeout(1000, function() self.sock:write(pwrConverted) end) self.sock:read({ success = function(data) self:debug("response data:", data) --self.sock:close() end, error = function(err) self:debug("response error wait ", err) --self.sock:close() end }) fibaro.setTimeout(1000, function() self.sock:write(pwrConverted) end) self.sock:read({ success = function(data) self:debug("response data:", data) --self.sock:close() end, error = function(err) self:debug("response error wait ", err) --self.sock:close() end }) end) end Looks like the connection is closed after frist call, but do not know how to keep alive, tried everything Can anybody help me? Regards

Hello All, I am looking for some help to create a virtual device for a epson projector that utilizes the PJLink protocol. that way it could be used for a lot of different projectors. I am a newbie and have little experience with coding, Any help would be gtreatly appreciated.
