don't work calibration on “esp32 uwb pro with display”

[Vorstok]

Hello, I wanted to calibrate using ESP32_UWB_setup_tag.ino and ESP32_anchor_autocalibrate.ino. But I am not getting new data for this_anchor_Adelay. What have I not done?

I used your DW1000_library
I am using the module “esp32 uwb pro with display”

I have not used that type of module.

The posted output shows no indication that the anchor and tag are communicating. That has to happen on both ends, before calibration can proceed.

Try the basic MakerFabs examples to see if the modules are working as expected.

I've tried using the basic MakerFabs examples. With tweaking the udp data transfer, I was able to see a few modules in python.

But I ran into a problem with anomalous data. Each pair individually Anchor-Tag shows the correct result. But Anchor-Anchor-Tag was showing incorrect data on the second module. For example, the distance can be 2 meters, but the sensor sometimes shows: 50 meters, -2 meters, 300 meters.

I assumed that calibration and filtering is necessary. I saw a convenient calibration on your github.

I will be grateful for any recommendations!

[Vorstok]

I found the solution. I just had to change a few things.)

How long does it take to calibrate?
Do I understand correctly that for calibration it is important to ensure direct visibility between the sensors and point them at each other?

[jremington]

A few seconds to calibrate.
Yes, the antennas should be visible to each other and parallel.

I tried using calibration, but at distances greater than 4.5 meters the signal is lost. I have used your advice. How to amplify the antenna power in code for anchors and tag?

[jremington]

With clear line of sight, I usually get around 10 m range with the original ESP32-UWB modules.

For longer range, use the high power version of the DW1000 library, up to 60 m with clear line of sight.

Dear @jremington.

As I understand your modernized libraries are not suitable for “esp32 uwb pro” boards Please add a clarification in README.txt that your library and pizzo00 library are not suitable for “esp32 uwb pro” and “esp32 uwb pro with display” boards. I'm sure this will help some people. I will try to work on their support.
Thanks.

For my development I am using only esp32 uwb pro

I got rid of this problem by switching from channel 5 to channel 1.

Wrote a package for ROS Noetic that visualizes the intersection point. Now at the stage of creating an algorithm to find the intersection point. Because the old algorithm is not working well.
