Hello,
I'm using STM32WB to scan bel beacons, i started from p2p_client example and modified it to scan all types of beacons it shows all close devices, their MAC address and RSSI power, but i want to show more beacons info like beacon name, type, beacon temperture, etc.
Can anyone please tell me what to add in my code so that i can get all the beacons information?

Hello,
You have to parse advertising data (adv_report_data) to recover your data. Advertising data have the following structure (see BLUETOOTH CORE SPECIFICATION Version 5.2 | Vol 3, Part C) :
adv_report_data = (uint8_t*)(&le_advertising_event->Advertising_Report[0].Length_Data)+offset;
A description of each AD type is available in this document:
Best Regards
