I am trying to implement a direct data communication between a master and slave device. I am using non beacon mode , and i dont want to use Polling feature of EX 6a and Ex6b. I just want to do the direct communication , assuming that my slave is on and waiting for a reply from master for the sent data(from slave). I did this in Polling base example. But i dont need that now , and when i tried this in direct way. It doesnt work. So , kindly guide me as i am running out of time for my submission.
