How to implement OTA upgrade in ble_central - ble_peripheral(bonded) application?

[role_2099]

My ble_peripheral is bonded to ble_central, How do I upgrade at this time? If you still use the mobile phone APP to upgrade, you need to erase the binding information, and then re-bind to the phone, then upgrade it. Is there any other way?

Thanks and Best regard!

Hi,

You don't need to erase the bond information. You can configure the Buttonless Secure DFU Service to either support bonds or not. With bond support, the application will exchange information about bonded devices with the bootloader. See this link.

Hi Sigurd,

Thanks for your reply. I missed an important point, my ble_peripheral is working in whitelist mode. This leads to another question, in order to prevent my slave device from being connected by other users, such as mobile phones, are there other ways besides the whitelist?
