用红宝石回应FM1100 GPS设备

Question

Teletonika FM1100首先通过发送确认包01来发送您必须响应的IMEI。我无法弄清楚我是如何发送它的。它只是继续发送IMEI，因为它不会以我想要的格式获得01.

以下是Teletokina协议文档PDF http://bit.ly/1OrmI9P的链接（第7页，服务器通信）

这是我的代码

require 'socket'                # Get sockets from stdlib

server = TCPServer.new 1337   # Socket to listen on port
loop do
  Thread.new(server.accept) do |client|
    client.print "\x00\x01" # also tried "\x01"
    print "#{Time.now.strftime('%d/%m/%Y %H:%M')}: #{client.read} \n"
    client.close
  end
end

我还尝试了client.write和pack以4种不同的方式

...
client.write [0x01].pack('C')

client.write [0x00, 0x1].pack('C*')

client.write [0x01].pack('N')

client.write [0x00, 0x1].pack('N*')
