- [Note] Tags using CR2032 are almost impossible to use due to rapid battery consumption. Unless it emits a signal very intermittently, practical use is impossible.

I actually have whole bunch of those UWF chips that I haven't taken the time to use for my project yet. I'm excited to see your progress.
I bought a few of these for a project but they are just riddled with flaws and limitation. First one being that the AES key can easily be exposed by querying it using AT command. This will enable people to easily clone the tag.
The second problem is that when you place it in TAG mode, you can't send messages actively to the anchor; thus it is impossible to announce yourself to the anchor that you are within the area so the anchor could know what to do next (constantly get distance etc.). The anchor itself have to guess which tag is within the area which is impossible to know unless you let the anchor brute force all of the known tags in your list and spam the RF spectrum constantly.
It is a neat little module for a school project demo with just one or two tags but for anything serious and more than that, I'd recommend avoiding it entirely.
Honestly I agree. To tell my story for a moment, when this module was first released, I was impressed that there was a uwb module that could be purchased and used instead of the dw series. However, I was very disappointed that the datasheet was very insufficient and included very minimal features. This is why I can't do the next project using it. Still, I appreciate that it can be used very easily for simple projects such as school projects.
What library are you using for the dwm1000 or dwm3000 since i can not find any official one ? only inofficial for arduino
As far as I know, there is no official library for Arduino. Also, I'm using the old library too. It seems that all companies that use this have their own implementation.
Really cool. Are those modules compatible with dwm1000? They support channel 5 so I suppose they are. I've got some dwm1000 as anchors and could I use this module as tag? If yes, could you make a tutorial how to use them together? Anyway thanks for great content.
It would be nice if RYUW122 was capable of more detailed settings, but anyway, let's try to see if the two devices can communicate.
Awesome, what's its max pulling rate? How many times per second can you get distance readings?
Not sure about the maximum pulling rate, but I think it is possible to have pulling data about 20~ 30 times per second. In my case, since it makes the battery consumption, I only tried minimal pulling.
Please implement reverse TDOA algorithm using this RYWU122 uwb module to detect the position of TAG😅
I mean TAG can determine its current location and the distance it is from the reference ANCHOR. It should be able to provide its location coordinates with reference to the origin ANCHOR.
what is max distance for the setup?
According to the datasheet, the maximum range is 100 meters in an open environment. However, it is expected to be very different in actual use. Let me try it in the next video.
When i am using a cr2032 , it's rapidly consumed ( in 5 mn or so 😮) am i doing something wrong? Did you experience it the same?
I also experienced the same issue. It only works the first time, and as time goes by, battery consumption increases rapidly, making it impossible to use in actual projects. More than the battery, the fundamental problem with this chip is that its functionality is so limited that it can only be used in very simple projects.
Can the Esp32 UWB see behind the wall? it's for a project
It will have very different results depending on the environment. This is why we must calibrate before use.
@@ThatProject I tried the similar scenario, it doesn't connect with the tag , also i looked upon lora but it can't provide TOF for distance measurement ! is there any other way to make it work?
ps lora can work incase of LOS through RSSI ** my case is NLOS
where can i buy module?
Maybe Amazon? amzn.to/49k6die
