Use UDP Broadcast packets assuming there is already wifi connection established between the devices. Connection establishment is managed by DisarmConnect App

ghoshbishakh commented 8 years ago

@archie94 As i had mentioned you need to use broadcast packets. So what you need to do is create two threads. one for broadcasting udp packets in the broadcast ip (192.168.43.255) and another thread for listening them and listing the peers

Thanks ! I checked and there is a bug in connection establishment between devices. Will use UDP broadcast packets

ghoshbishakh commented 8 years ago

assume two devices are already connected over wifi. Now the goal is to autometically detect the presence of the devices on the same network. Thats why UDP broadcasts are required.

Example:

PhoneA and PhoneB are connected to the same wifi

So target is: in phoneA print: ip address of PhoneB

and in PhoneA print: ip address of PhoneA

Having problem in receiving the broadcast packet in client side. Definitely the problem lies in joining the socket to the broadcast group. Need a little help.

@ghoshbishakh Writing the file manager with reference to your python script. Not clear on two things

  1. what does def checkChecksum(self, fileId) do?
  2. how to generate fileID for each file present?
ghoshbishakh commented 8 years ago

@archie94 actually that calculates the checksum of the file content and assigns it as fileID. Leave that part or hardcode something. Push whatever you have done till now.

archie94 commented 8 years ago

@ghoshbishakh Pushed works up to today. I cannot work for the next two days. If you can you may modify whatever you feel like. Will resume from Saturday.
