Currently i am working on heart rate monitor and i found that "2A37" is uuid which is used for getting heart rates data from hrm device. Then i searched a lot but i don't find, why i should use "2A37" and not other for getting heart rates data.
I have gone through the information of below link of bluetooth site but still i am confused.
https://developer.bluetooth.org/gatt/services/Pages/ServicesHome.aspx.
Can anyone please make me understand how can i decide different uuids for diffrent services.
Example: Suppose i need to get battery data from hrm device then, from Bluetooth services information how can i find UUID of battery services data.
Thanks in advance.
