reverse engineering a proprietary UART protocol
This sounds cool and all but then
Turns out it was just standard 8N1 115200-baud UART.
I didn't see any mention of this proprietary UART protocol in your blog and the GitHub project looks like it was as simple as reflashing the onboard ESP32 once everything is wired correctly?
Does this work for units that don't have anything smart in them? I have 3 units 200 something without any sensors, Bluetooth or wifi connection
Gawd yes I've been sitting on these things for like 3 years waiting for someone smarter than me to come up with something. Thanks for the share!!
I have been following along here, trying to learn what I can to be an informed buyer for when I try to get into this. Today I learned I have already made an informed purchase 🙂 I want to reprogram my unit just to see if I can change what it does in a loss-of-power event.
Thanks for sharing!
