Re: nRF52832 General purpose retention register (GPREGRET) and Zephyr FOTA
Hi Rodrigo,
I am not an expert on persistent storage, but if your system undergoes frequent cold resets then the system will need to write to flash. You may refer to flash API, circular buffer or

Re: nRF52832 General purpose retention register (GPREGRET) and Zephyr FOTA
Thank you very much.
I was taking a look at the NVS system.
Let's see if it could solve the problem to me.

Hi Rodrigo,
GPREGRET is general purpose retention register in the SoC, which only retains value across warm resets.

Thank you very much, Vinayak.
Any clue on persistent storage and ultra-low power?

nRF52832 General purpose retention register (GPREGRET) and Zephyr FOTA
Hi fellows,I am developing an application that counts pulses from a source. I need this system to be the lowest power possible. I was wondering if I could use the GPREGRET register do store this

Re: [Zephyr-devel] switching from #FCB to #NVS for #BluetoothMesh persistent storage

Hi.
I Think it will be possible – (but can’t be sure). At last Jehudi Maes (the NVS author) is considering right now ho to provide nvs-back-end for the setting (I’m in touch with him).

Hi Vikrant,

the future with NVS).

Hi Andrzej,
Is #BluetoothMesh stack completely independent from persistence storage mechanism used by #SettingLayer ?
If yes, then only it will possible. 😃
Thank You !!

Re: mcuboot + dfu-util on nRF52840 not able to update firmware

this is what I'm seeing in dmesg:

Re: mcuboot + dfu-util on nRF52840 not able to update firmware
Hi Pawel,
The issue with the timeout is a well known one. I think Johann had a proposal, but first we need the stable driver to be on master.

Re: mcuboot + dfu-util on nRF52840 not able to update firmware
What does dmesg say?
In my case it is detected, but I have noticed 2 issues:
selecting alternate interface does not work, so image-1 cannot be flashed
image erase takes over 10sec which cause timeout

Hi,
will it be possible to choose between #FCB & #NVS for #BluetoothMesh persistence data storage using configuration options ?
Thank You !!

Re: mcuboot + dfu-util on nRF52840 not able to update firmware
Pawel,
I tried out the DFU sample on your branch, and I'm not seeing the device show up as a DFU capable device. If I run sudo dfu-util -l it doesn't show up in the list, and if I run sudo dfu-util

Re: Setting a default public MAC address in Zephyr HCI samples
Yes Carles, that is what we're trying to do. I've gone ahead and forked the repo so that I can change the reset function to apply the public MAC stored in the UICR.

Re: Setting a default public MAC address in Zephyr HCI samples
So let me get this straight, you program the address into the UICR during production, and then you want the controller to read it from there right?
In that case unfortunately you will need to

Re: [Zephyr-devel] about newly introduced #BluetoothMesh persistent storage feature
#bluetoothmesh
Hi Johan,
As per nrf52840_pca10056.dts file last 16KB is used for persistent data storage.
To calculate FLASH life time, I have to understand what is going on at background (at #FCB layer).

Re: [Zephyr-devel] about newly introduced #BluetoothMesh persistent storage feature

Hi Vikrant,
The currently implementation is purely based on settings, so you can
just register your own settings subpath to store app-specific
information. I'd advise to use something else than "bt/"
