I have started with a project that needs to communicate with the BLE sensor tag module CC2541.
Till now, I have been able to search the device make connection between my android app and the sensor tag but i have no clue how to start with the communication henceforth.
There is a confusion regarding the UUIDs required for every service. Since, we I will be using a PIR sensor on the micro controller side and program has been developed for the same.
I wish to understand that are these UUIDs generated randomly and do I need to mention them in my C header files or its just required in android with any random value.
Thanks
