Dfu Mesh

[Zhenya Zh]

Hi, i want to use dfu for application with mesh. But i want to update via ble in direct connection with phone, not via mesh protocol. Should i use example from mesh sdk or from ble sdk?

Hi. 

I suggest you take a look at this previous thread.

Thank you. I am using experimental_lpn example, but i have error.

00> <t: 0>, main.c, 521, ----- BLE Mesh LPN Demo -----
00> <t: 0>, app_error_weak.c, 119, Mesh error 4 at 0x00000000 (:0)

I found that its error from nrf_dfu_svci_vector_table_set(), because no bootloader was found. Do i need to download bootloader from Secure Bootloader example first? How can i do this from ses? When I try to download secure bootloader first, than experimental_lpn example, the second is not started.

My steps:
1. I follow this guide for start Secure Bootloader example 

2. I run experimental_lpn example without erase, but in Debug mode application "running..." infinitely. When i press "break" i can see that application stopped at   00015F5A BF40  sev in dissasembly .

And one more question. Can I erase application, but not erase bl and sd using ses?
