How to make the matching and binding equipment information would be stored permanently, even after the OTA upgrade is still in

[???]

HI: everyone! How to make the matching and binding equipment information would be stored permanently, even after the OTA upgrade is still in;I made with examples of the official, the program of heart rate, for now, matching, binding and OTA has achieved, but there is a problem, is when I have good matching and binding equipment information, through OTA upgrade, after the original match was gone, through the LOG print to see before binding equipment information already all clear；My English is very poor, this is through the translation software, hope you can understand; 1:my sdk version is sdk9.0; 2:sd version:sd 8.1; 3:I USE code in the bond!

I you want to preserve bonding information through a OTA DFU you have to edit the DFU_APP_DATA_RESERVED define in `dfu_types.h. This is described on this page in our Infocenter.

Update:

Thank you, I described according to the change of 0 x1000, but print LOD displayed after the OTA didn't last binding information, as well as the above is cleared what should I do？ after OTA ，LOG： 14:02:15.488 [DM108]: >> BLE_GAP_EVT_SEC_INFO_REQUEST [DM9:[DI 0x00: Device type 0xFF. [DM10: Device Addr 0xFF 0xFF 0xFF 0xFF 0xFF 0xFF. [DM9:[DI 0x01: Device type 0xFF. [DM10: Device Addr 0xFF 0xFF 0xFF 0xFF 0xFF 0xFF. [DM9:[DI 0x02: Device type 0xFF.
