Security db problem

Hi all,

I am facing a problem with the security dababase, I am working with BLUENRG-1, I can paired two devices and getting them advertising and create connection, then close the connection and connect again...everything is working fine.

If after all the process I remove the battery from one of the devices and put the batteries back, I can't create a connection again, if I go to the memory position on the bluenrg-1 I can see the address from the device paired there but for some reason I can get them connected again if I do not follow the pairing process.

Any suggestion why that problem could be.

Thank you
