how to verify mesh DFU no serial example dfu_no_serial_nrf52833_xxAA_s113_7_0_1

[ivnn]

Hi,
I'm working on DFU mesh no serial example (dfu_no_serial_nrf52833_xxAA_s113_7_0_1 ) and want to know any way to check it maybe by using nRF Toolbox or nRF Connect mobile application?

for now my steps are next one:

1. nrfjprog --eraseall

2. nrfjprog --program s113_nrf52_7.0.1_softdevice.hex --chiperase

3. nrfjprog --program mesh_bootloader_gccarmemb_nrf52833_xxAA.hex

4. nrfjprog --program dfu_no_serial_nrf52833_xxAA_s113_7.0.1.hex

5. nrfjprog --program device_page_nrf52833_xxAA_s113_7.0.1.hex

6. nrfjprog --reset

7. python bootloader_verify.py 68xxxxx00 COM25

after all of these steps, the application is starting and log output is the next one

while scanning with nrfConnect app device is appear as 



1. seems it does not support connecting to it, should it? to be able to connect and upload zip update
2. maybe something goes wrong on this stage ? 8229>, ble_softdevice_support.c,  171, sd_ble_enable: app_ram_base should be adjusted to 0x200018F8

Hi ivnn,

Have you followed the instruction here on how to do a DFU update? You must test with a "with serial" example first before you can test with "no_serial"

To be able to test with a "no_serial" you would need to have at least a "with serial" to connect to PC to receive the image. The node connected to UART to PC will act as the bridge to spread the image out to the mesh network and update those "no_serial" nodes. 

Note that you can't use nRF Connect to do DFU update, you need to use nrfutil tool on PC to do it. 

The log note about adjusting ram is just for optimizing the RAM setting for application, it's not related to DFU update.

Hi, thx for the detailed answer for now it's clear
