Nearable scanning stopped after about 20 seconds

I recently got a package of estimote stickers. I plan to use the accelerometer data. However, when I tried to scan the accelerometer values, they do not vary (i.e., keep showing the same value) over time. After about 20s, the nearable scanner even stops.

I am on LG V20, android 7.0. I’ve ever read somewhere that this problem could be android device specific. With regard to this, I plan to use Android low-level Bluetooth API for a workaround. Is there any guide about extracting raw accelerometer value from the advertised packet?
