UART on Ring Doorbell 2nd gen
Any here that have any experience with UART?
I have a Ring Doorbell 2nd gen I need to find it on for my bachelor project but cannot seem to find it. If anyone have any idea I will be happy to share pictures of the board for any pointers.
I have been looking at a lot of different guides, including that one. My problem probably is that this is my first time actually even looking at a board so I have no clue what I am looking for. I tried probing using my multimeter as well, but I really have no clue what I am looking for, where and what I should probe.
Seeing guides saying find GND by probing this and this, and my board is not looking close to the same so I just keep scratching my head
I will be happy to share pictures of the board for any pointers.
Maybe post clear photos of the board
@aakra if the manufacturer's Ring Doorbell PCB is consistent with their current security approach to remove and/or reduce attack surfaces as mentioned in this article https://medium.com/tenable-techblog/inside-amazons-ring-alarm-system-9731bc519974 then hunting for UART might not give you what you are looking to achieve.
Thanks for the photos, I will look at them tomorrow.
I think even experienced electronics engineers would have trouble with this (if it wasn't their own boards and didn't have a circuit diagram).
Are you even sure there is even a UART on the board in question?
Maybe you should be looking for a JTAG interface?
