Data format sent from Device to android app via Bluetooth Low energy

Nithin Nagaraj

I am trying to run a BLE example code( Heart Rate Sensor) to send  from my device to android/ios app. I am able to send the data from my device to Android/ios BLE app. Now my questions are,

1) In what format (JSON/XML) the data is sent from device to android?. I am aware it should be mentioned in the program.

2) Since i am trying to send the health parameters like heart rate, Blood Pressure etc. should i follow theIEEE  format compulsorily to send the data?. It is different for different body parameters.

The IEEE data specifications link is given below. 

If i have to follow the IEEE format then do i have to set different profiles for all the different parameters( Heart rate, glucose, Blood pressure etc)?. I am using CC2650DK. Please help me out, i am relatively new to Bluetooth technology.

    Hello Nithin,

    Welcome to BLE! If you use the adopted profile, including the 16-bit UUID, you'll need to follow the data format in the respective Service / Profile. Otherwise, you'll need to create a custom profile and use a custom 128-bit UUID.

    I suggest taking the SimpleLink Academy training program on the BLE Wiki, it will cover the process for creating a custom profile.

    Best wishes
