Random MAC Address with cell phone

I am developing with the CSR1010 with the CSRmech Development Kit. I am having problems with the master / slave functions with the MAC address and the type (public or random) that the LM_EV_CONNECTION_COMPLETE_T API structure returns when establishing a connection with the cell phone. Even configuring CSR1010, in SDK 2.6.0.10 using GattConnectReq with the flags configured to connect to public MAC Address, when connecting to the cell phone, it reads a random MAC Address different from the MAC address of my cell phone. This happens with all Bluetooth 5.0 phones.
 
For example: I connect my cell phone to my CSR1010 module using GattConnectReq (NULL, L2CAP_OWN_ADDR_TYPE_PUBLIC). My phone has the starting MAC address "48: 2C", in debug mode, after connection, in the structure LM_EV_CONNECTION_COMPLETE_T -> HCI_EV_DATA_ULP_CONNECTION_COMPLETE_T -> BD_ADDR_T returns a completely different MAC Address value, in addition to being listed as Random MAC.
 
I would like to know how I can make a connection and read the correct MAC Address from my cell phone, the public type.
