CC2650EM-7ID-RD: Direct Advertising - How to use it

Part Number:CC2650EM-7ID-RD

Hello,

I'm trying to get the direct advertising to work on my two SmartTF06 dev boards with the CC2650EM shield. But I cannot get it to  work, maybe you can help me with a few questions.

1. Do I have to change the mode of discovery for the central device or should the directed advertising packets be found just like the undirected? At the moment I do not receive anything from the peripheral when directed advertising is enabled.
2. Should the directed advertising packet even be found by the central if there was no prior bonding? I other words, can I just use hard coded adresses on the peripheral side to address the central?
3. I found some threads in the forum noting that the address given for GAPROLE_ADV_DIRECT_ADDR should be reversed, is this true?

The SDK version is "ble_sdk_2_02_02_25".

I've started with the simple_peripheral and simple central and changed the following:

Peripheral:

SimpleBLEPeripheral_init(){

...  after all the GAPRole_SetParameter calls I added:

    uint8_t resolvedAddr[B_ADDR_LEN] = {0x00, 0x2f, 0xdc, 0x43, 0xb4, 0xb0};
    uint8_t idx = GAPBondMgr_ResolveAddr( advDirectAddrType, resolvedAddr, NULL);

    if ( idx < GAP_BONDINGS_MAX ){

        uint8_t advDirectType = GAP_ADTYPE_ADV_LDC_DIRECT_IND;

        bool bIsEnabled = false;
        GAPRole_SetParameter(GAPROLE_ADVERT_ENABLED, sizeof(uint8_t), &bIsEnabled);
        GAPRole_SetParameter(GAPROLE_ADV_DIRECT_ADDR, B_ADDR_LEN, resolvedAddr);
        GAPRole_SetParameter(GAPROLE_ADV_EVENT_TYPE, sizeof(uint8), &advDirectType);

        //GAPRole_SetParameter(GAPROLE_ADV_DIRECT_TYPE, sizeof(uint8_t), &advDirectAddrType);

        bIsEnabled = true;
        GAPRole_SetParameter(GAPROLE_ADVERT_ENABLED, sizeof(uint8_t), &bIsEnabled);

Display_print0(dispHandle, 5, 1, "bonded!");
Display_print0(dispHandle, 6, 1, Util_convertBdAddr2Str(resolvedAddr));
Display_print0(dispHandle, 7, 1, "Directed");

}

Central:

#define DEFAULT_DEV_DISC_BY_SVC_UUID          FALSE

For the Central the evaluation allows to list all the found MAC-Adresses but the address of the periperal device does not show up. Do you have any hints or can somebody provide a working example?

Best regards
