How to reject BLE connection request.

HI All,

HW: CC256x
SW:  bluetopia -Version-1.1

I am using bluetopia on PAN1323ETU module. I am looking to establish a secure connection in both BT  & BLE mode. For this I have selected SPPLE demo as start point & working in LE mode.


After running the demo I observed that, whenever client sends a connection request to slave, slave accepts connection request and connects automatically. I see some options in BR/EDR mode to reject the incoming connection after switching to manual Accept mode. is there any such options available in LE mode?

Please let me know.

    Hi,

    Have you enabled Man In the Middle Mode?. You can set this by calling the function before starting GAPBond Manager 

    mitm = TRUE; //1

    GAPBondMgr_SetParameter(GAPBOND_MITM)PROTECTION, sizeof(uint8_t), &mitm);

    Regads,

    Arun

    HI Arun,

    Thanks for your reply.

    I don't see any API's like GAPBondMgr_SetParameter(); in bluetopia stack. Instead MITM information and device capability informations are exchanged only when a pair request comes. Since I am operating as slave, I will exchange these information with master when a Master sends a PAIR request to me.

    So, If a master try to read or write my characteristic table without pairing, I am allowing it to do So ! I want to restrict any device to perform read/write operation without authentication.

     

    Thank you.

    Hi,

    Setting up the device as a white list would work. You can also try to force encryption and pair if the device is known. This topic might help, http://e2e.ti.com/support/wireless_connectivity/f/538/p/306153/1081626.aspx#1081626
