I am trying to send text data between two Android devices using a beacon. I am using the Bluetooth Low Energy API to develop an application. But I am stuck in reading data.
Whenever I try to set values for characteristics, another device cannot receive data. GetValues characteristics return null.
I already asked this question in another thread on Stackoverflow . But once again I transmit my requests in graphical format.
This is the above image explaining the scenario.
Please offer me some solution and technique to solve my problem.
