Can you elaborate on "pBeacon"? Do you have any links or references to further explain what you mean?
Typically, a BLE device advertises using BLE advertising packets. The content of the packet is under the governance of the BLE server that is transmitting. The content of the packet must adhere to the BLE specifications and can contain fields of pre-defined structures. Those can include the devices name, exposed service UUIDs, manufacturer data and more. There is a limit to the amount of data that can be contained within a single advertisement.

Hi
don't know what a "pbeacon" is, but if you meant iBeacon, the framework does include an example about how to scan for those devices:

maybe you can change it to search for "pbeacon" specific advertising data...

You can filter/scan/connect to particular devices based on:
1. the ble services they are running (uuid filter)
2. based the ble hardware mac

Hello,
pBeacon is same as iBeacon.
Actually,i can also detect devices whose bluetooth is ON.
So,i have detecting number of extra devices instead of pBeacon's list.
Thanks.

You can filter all bluetooth le devices and search only those with UUID FDA50693-A4E2-4FB1-AFCF-C6EB07647825, at least this ive found on aliexpress.
