When i try to bond from Master Control panel, it disconnect with this message: [17:27:07en-USTelligent Community 13Thu, 20 Feb 2014 18:26:45 GMThttps://devzone.nordicsemi.com/thread/7364?ContentTypeID=1Thu, 20 Feb 2014 18:26:45 GMT137ad170-7792-4731-bb38-c0d22fbe4515:9fdd7cb2-7be3-4619-9f5d-bfb537b9e33bthomas<p>my new version : <a target="_blank" href="https://devzone.nordicsemi.com/index.php/nrf_error_invalid_param-error-code" rel="nofollow">https://devzone.nordicsemi.com/index.php/nrf_error_invalid_param-error-code</a></p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/7363?ContentTypeID=1Thu, 20 Feb 2014 11:37:33 GMT137ad170-7792-4731-bb38-c0d22fbe4515:e38a76a3-68f2-4f37-80ba-fa65bceec6ddOle Morten<p>First of all, I&#39;d strongly recommend you to follow the recommendation <a href="https://devzone.nordicsemi.com/index.php/problems-with-reset-loop-s110-softdevice#reply-5125">here</a> to catch your errors more easily.</p> <p>In your case, I suspect that is the BLE_GATTS_EVT_SYS_ATTR_MISSING event being handled both in your main.c and in the bond manager that causes the problem. When doing this, the second ble_gatts_sys_attr_set() call will most likely fail in some way.</p> <p>For an example of what kind of changes are needed to start using the bond manager, you can take a look at <a href="https://github.com/NordicSemiconductor/nrf51-ble-app-lbs/compare/require-encryption-5.1.0">this branch</a>, that I just pushed to GitHub. It shows the basic changes needed to start using the bond manager in the <a href="https://github.com/NordicSemiconductor/nrf51-ble-app-lbs">nrf51-ble-app-lbs</a> application.</p><div style="clear:both;"></div>
