ble_app_hrs_c example fails reconnect on SDK 15.2.0

[Jacques]

Hi,

I'm using a PCA10040 devboard to test the heart rate client example. I see that when using the example from SDK v15.2.0, I can connect to my (Polar) heart rate device, and if I reset the devboard, it will recognize the sensor and reconnect. However, if I power off the sensor, and power it back on, I get an error "PM_CONN_SEC_ERROR_PIN_OR_KEY_MISSING".

I did the same experiment using the example from the SDK v14.2.0, and that one reconnects with no issues. 

I'm not sure if this is a peer manager issue or to do with some security option.

Any ideas?

Could you let me know what's the problem you have with the sniffer ? It's very important to get the sniffer trace to really understand what's wrong. 

Also please capture another log with the full log from the time you bond to the device (first connection ) . Before testing please make sure you erase the flash fully and delete bond on the Polar.
