WHAT IS THE PROCESS OF ADDING THE SERVICE IN THE WHITE LIST ?

WE ARE FACING DISCONNECTION ISSUE AS ANDROID KILL THE SERVICE. I READ CODE OF CYCLIC SENSOR WHERE

// Duration of advertising to white list members only after link termination
#define DEFAULT_WHITE_LIST_ADV_DURATION 10000

#define USING_WHITE_LIST TRUE

WHAT SHOULD BE THE SOLUTION TO AVOID DISCONNECTION AND AUTO RE CONNECTION

Thank You.

Hi Luis,

Thank you for your support.

Currently we are using BLE-CC254x-1.5.1.1.

I tried with the code available in the ble under project folder Simple BLE Peripheral ,Cyclic Sensor.

As we run the code and upload into PCB we are unable to visualize it into BLE Scanner App.

Is their anything i am missing

Waiting for response.

Pallavi,

Please apologize for the delay;

The white list is applicable to addresses (not services), and its behaviour varies if is being used on the peripheral or central. In this case, the two discussions below talk about whitelist usage on your device, which also points to additional resources.

Please note these are applicable to our software and devices - we can't control the Android/iOS part of the connection.

Hope this helps,

Rafael

Hello Rafel,

Thank you for your reply. My device is working in a peripheral mode and it is advertising. While Mobile developed by us works as a central and in the scanner mode.

We have two things here 1)communication between Device(peripheral)-- Central(App)

2)Communication between the App and the Operating system (Android/ios)

If we add whitelisting function as per mention in the cyclic sensor code in the peripheral does it resolve the issue of disconnection and includes auto reconnection between the device and App

Address you mean to say MAC Address.

Please elaborate, what do you mean by a public address and private address?

Regards,

Pallavi

Public and private addresses are defined by the specification. A good reference can be seen at:
