LAUNCHXL-CC2640R2: Authentication Characteristic

Steven Cao
Intellectual 310 points

Part Number: LAUNCHXL-CC2640R2

I am running 'Multi-role' project on CC2640R2 LaunchPad.

I can use a BLE applications on my iPad to connect to the board.

In 'Multi-role' project, the value of characteristic 5 is a 'GATT_PERMIT_AUTHEN_READ' type. In other words, it requires 'Read requires Authentication'.

But, I did not see the code to implement this feature here:

CONST gattServiceCBs_t simpleProfileCBs =
{
  simpleProfile_ReadAttrCB,  // Read callback function pointer
  simpleProfile_WriteAttrCB, // Write callback function pointer
  NULL                       // Authorization callback function pointer
};

Do you have any sample code and documents for this feature, 'Read requires Authentication'?

Thanks,

Steven

    Hi,

    Authentication is not the same as authorization.
    Authentication is after you successful paired with MITM method, then you can access the characteristic.
    In multi-role with phones, you will get to entry the passcode, after the correct passcode is entered, you will be able to read the characteristic 5 value.

    For more information regarding authentication and authorization, please take a look at BLUETOOTH CORE SPECIFICATION Version 5.1, Vol3, Part G, section G.
