  • What is the problem you are facing here? Any error messages? – powerPixie Jan 13 '20 at 09:48
  • @powerPixie there is no error but I don't want to use scaledrone.js – Tut neil Jan 13 '20 at 09:59
  • You need to use some sort of signaling service to connect two peers. In your case scaledron is a signaling service.without signaling service you cannot initiate connection beween two peers.how are going to connect to peers? – Serdar Jan 15 '20 at 15:57
