I'm using the Texas Instrument CC2540. 1. I would like to understand why the device UUID has a different value when visible from different iPhone / iPad How to have an unique UUID for each BLE device ?

We are trying to avoid the case where you could crowd source the location of people based on the devices around them. However, if you have a good use case, we should have a good discussion about that.

2. I have modified the deviceName info from the broadcast data with: GAPRole_SetParameter( GAPROLE_SCAN_RSP_DATA, sizeof ( deviceName ), deviceName ); The pb is that it is very easy to "fake" the tag by using the same deviceName on another tag... How to avoid the pb ?

There is no guarantee that the name uniquely identifies the device. One way would be to connect to it and read a serial number from the device (if it supports the Device Information Service or similar service).

3. attTagName: GGS_SetParameter( GGS_DEVICE_NAME_ATT, GAP_DEVICE_NAME_LEN, attDeviceName ); When use this parameter ? why it is different to the deviceName ?

You might want to contact Sandeep Kamath <sandeepkamath@ti.com> at TI regarding this. _______________________________________________ Do not post admin requests to the list. They will be ignored.
