Hi @victor,

Thx for this. I’ll take a look at it in a free moment.
I understand this has also the new interval setting for the noise?

Hi Victor,

This is great work, thanks to you and everyone on the team for moving things forward.

I’ve tried just now to do the update, my green light is blinking and it does not complete. Do you have any advice to debug this situation?

UPDATE: I’m reading the page on how to edit the firmware: Edit the firmware - Smart Citizen Docs

Is there any way to get the previous SAM file?

As I’m not able to install the ESP file (trying to do it through the phone doesn’t work), and I got my SCK complety useless.
