Distance bluetooth range Arduino Nano 33 BLE

[thm14]

Hi everyone!!
I am using an arduino nano 33 BLE board to record accelerations of a moving object, but my computer barely gets a bluetooth connection until about 45-50 [cm], which is clearly too little (attached the bluetooth version of my computer ), on the other hand, when establishing a connection with my smartphone (Bluetooth version 5.0) through bluetooth scanning applications such as nRF Connect or BLE Scanner I get distances greater than 5 meters! That would help me for my measurements, I had read that the casing probably covers the sensor antenna, so I broke that wall of the casing, but I still get the same result, I also checked the soldering points of the antenna and everything seems to be in order (attached photo) does anyone know how to improve the distance when using the computer to measure? by the way i am using the BLE protocol for communication.

A poor quality built in antenna on your computer may be the cause. Capture the data using your smartphone.

Finally I was able to solve it, I bought a bluetooth adapter for my computer, specifically "UGREEN 80890 USB Bluetooth Adapter", I tested the sensor in its casing, up to 7 or 8 meters, no problem in the measurements, so if it was the bluetooth card of my computer.
