BLE - Whitelist not found

Roei

Hi,

I'm using nrf52840 and connecting to a mobile device via BLE.

After bonding connection, I'm restarting my nrf device in order to start advertising again, with whitelist.

The problem is that sometimes - whitelist isn't found and I can't start advertising. In other cases - it works fine.

Can you please help me?

Thanks!

    Hi,

    I assume you build the whitelist based on the existing bonds, and so the reason the whitelist does not exist (or cannot be generated) is probably that there is an issue with the bond. Could it be that you reset the nRF before the bonding information was written to flash? Or is this reproduced also when waiting a while between bonding and resetting the nRF? Does it also happen if disconnecting the BLE connection (for instance by turning on airplane mode on the phone) some time before resetting? By the way, which SDK version do you use?
