How to delete the previous bonding information from central?

[Hrushi]

Hello Nordic Experts,

I have One central device and and 4 peripheral devices. At this point of time I am trying HRS example on it, the example is running fine with single peripheral. Then I try the same central but different peripheral but its not connecting to that peripheral.

Again, when I tried the same peripheral I observed I am getting below log "app: Connected to a previously bonded device." from below snippet

switch (p_evt->evt_id)
{
    case PM_EVT_BONDED_PEER_CONNECTED:
    {
        NRF_LOG_INFO("Connected to a previously bonded device.");
    } break;

Now my questions are :

1. How can I delete the previous bonding information?

2. How can I add these four peripheral device to the Whitelist?

Best Regards, Hrushi

You can delete a peer/bond with pm_peer_delete(). You delete all peers/bonds with pm_peers_delete().

You are probably not connecting because you are scanning with a whitelist with the first device. If you want to connect to another, scan without whitelist.

If you want all devices in the whitelist you can scan without whitelist until all have bonded, then scan with whitelist.

You can also create a whitelist that is not based on bond information. Then you will have to hard code in the addresses of the devices you want in there. There are some questions in here on how to do that.

Your not below log "Whitelist temporarily disabled"? What does that mean?

If you see inside scan_start() you can see that if m_whitelist_disabled == true scanning should start without whitelist:

if (((addr_cnt == 0) && (irk_cnt == 0)) ||
    (m_whitelist_disabled))
