Hi wim, Please have a look at this case.

Make sure you have configured the IROM1, IRAM1, IRAM2 in the project setting correctly. Secondly, make sure dfu_ble_svc.c file is configure so that it has "Memory Assignment" of Zero Initialized Data at IRAM2. How do I do that? in my project IROM1 is set to start 0x3C00 and size 0x3C00, IRAM1 is set to 0x20002C00 and size 0x5380, and IRAM2 is set to start 0x20007F80 and size 0x80. Furthermore, on IROM1, IRAM1 and IRAM2 the 'default' checkbox is checked, and on IRAM2, the NoInit checkbock is checked. Or in other words: I kept the defaults of the (Keil) project. Do I have to set different values for these fields? And how do I do memory assignment of zero initialized data at IRAM2?

@wim: You need to reconfigure the bootloader to make it debug-able. You can have a look here on how to do it, at section F. dfu_ble_get_peer_data() shouldn't cause any trouble, what it does it to check if you have peer data in IRAM2 to re-encrypt the link. In your case you would not have anything there and the function return NRF_ERROR_INVALID_DATA. This is normal.
