SDK15 pm_conn_secure() doesn't bond

[Mikhail]

Hi!

After connected and get log info "Connected." I start bonding:

// Initiate bonding.
err_code = pm_conn_secure(p_ble_evt->evt.common_evt.conn_handle, false);
if (err_code != NRF_ERROR_INVALID_STATE)
{
    APP_ERROR_CHECK(err_code);
}

but there is no any success message. 

 0> <info> app: Heart Rate collector example started.
 0> <info> app: Starting scan.
 0> <info> app: Connected.
 0> <info> app: Disconnected, reason 0x8.
 0> <info> app: Starting scan.
 0> <info> app: Connected.

 0> <info> app: Connected.
 0> <info> app: Disconnected, reason 0x8.

Therefore nRF52 SDK15 can't to made secure bond.

Why?

The SDKs do only provide a higher level abstraction, so different SDK version should not matter. In the application, for both central and peripheral, could you set the logging level to "debug"? And also enable logging for the "peer manager" module?

With the above settings, could you do the following bonding tests:

• SDK15 <--> SDK13: not working
• SDK15 <--> SDK 15: working (for the peripheral, use a SDK example)
• SDK13 <--> SDK 13: working (for the central, use a SDK example)

And then upload the logs here.

Hi! I use RTT debugging. How to set logging for peer manager?

SDK15--SDK15- all OK

SDK13--SDK13- all OK

SDK15 perph --- SDK13 central- OK

SDK15 central ---- SDK 13 periph- doesn't works.

how to enable logging for peer manager?

[FormerMember]

I thought it was possible to enable logging for peer manager, but I see that it is not.. Instead, could you use the sniffer to track the on-air traffic?

[Mikhail]

Yes, I'll use sniffer. But at Wednesday. Ok?

And let's enable logging for peer manager. How to enable it?

[FormerMember]

That's fine.

It is not possible to just "enable" logging (like I first thought). If you want to add some logging (very useful), you can add it in each event in the peer_manager event handler in main.c:

case PM_EVT_BONDED_PEER_CONNECTED:
{
    NRF_LOG_INFO("PM_EVT_BONDED_PEER_CONNECTED");

 }

[Mikhail]

Yes, understand now.

Ok, tomorrow I'll sniff traffic and upload it.

[Mikhail]

I sniffed traffic.

Attached. One more. This is central SDK15 and periph SDK13. Doesn't bond
