How was the day when your invention finally worked?

Hi,I am Jaap Haartsen,when i invented the Bluetooth i was really happy because i revolutionized the world with it.My world was simple but that day it changed my life,I explained everybody how it works, and today most of the cellphones,video games,computers and printers had this installed.

When I started creating the Bluetooth I failed,I sat in a chair in a room, and I was very sad,but I continued and I though that I can not threw the work in that manner,so I sat in a chair to look what I had done wrong,and I found it,I did put the cables bad,they were not good connected, and I connected good and it functioned.

The Bluetooth is something that don't need connection to internet is  a wireless connection that does not needs cables to operate,and many devices can use the Bluetooth so they can pass information without the cables. Video games can pass the information to play together with the need of internet.
