To broadcast messages securely a 4-digit PIN is generated in the App which needs to be shared between the friends who can receive the message.
The receiver parties can receive the message when they come within the range as long as the message is being actively broadcasted. The broadcast can be stopped anytime by selecting the option “stop ongoing broadcast” from the action bar at the top.
To broadcast a message, simply type the message and select time till it needs to be broadcasted to the authenticated receivers. The PIN can be regenerated anytime by selecting the option “regenerate new pin” from the action bar at the top.
