Am using ibeacon which has temperature , humidity and accelerometer sensor. when i use "nRF connect " app i can see two scenario . 1st scenario : in the service data i can see the Mac , major , minor ,power , broadcast interval , battery . 2nd scenario : in the service data i can see the sensor data ( ibeacon word flashes beside the name ) but when i try to see these data using “BLE Viewer BLE data viewer for AB BLE Gateway V4” . i only get mac , parse address , uuid , major , minor , rssi . but i need the sensor data . ![Capture](https://bbs.aprbrother.com/uploads/default/original/1X/a643825aa3d862b62206c2761d78c2e25eb73170.jpeg) thank you . ---

Please change the `Advertising Filter` from `iBeacon Only` to `Allow all advertising data`. Because the sensor data from the BLE device is not iBeacon protocol ---

Changed to allow all advertising data , now am getting from other Bluetooth devices also . any idea how can i filter this and get my designated ibeacon advertising data only ? ![Capture11](https://bbs.aprbrother.com/uploads/default/original/1X/3753411d2867a02ea07d25c56d0a08a06ac2cb26.jpeg) any idea what will be in the Manufacturer ID Filter for my beacon ? or how to check this data ? already read this [April Brother Wiki](https://wiki.aprbrother.com/en/User_Guide_For_AB_BLE_Gateway_V4.html#application-options) . but still could not find for my case . ---

How many beacons do you monitor in same time? Please try the mac address filter ![mac address filter](https://bbs.aprbrother.com/uploads/default/original/1X/777b83a1700a1a991ea0253295bfc8459e5f7d9e.png) You can fill mac `C42BC1580D27` for your beacon. `00` is wildcard bit for the filter. e.g. `C42B00000000` will match all mac addresses which start with `C42B` ---

You can input multiple mac addresses. One line for one beacon. e.g. ```auto C42B00000000 C42B00000012 C42B00000034 ``` ---

thank you for all the help . just one last question . What to do if I have 100 beacons , as its quite hard to set mac address for 100 beacons . Is there any alternative to it ? Like can I set Manufacturer ID to filter the beacons ? As all beacons which I am using are from same company . ---

Yes. You can use Manufacturer ID filter if you choose “Allow all advertising data”. see the screenshot. ![mfg id filter](https://bbs.aprbrother.com/uploads/default/original/1X/5dbd89fb5b87cbd51da77b4bbc658795816c7357.png)
