Hello.
I am trying to get data from the A&D tonometer on my orangepi 4. The devices are pairing successfully, but reading attributes is not available, services are also unavailable. This behavior is observed on various orangepi distributions (armbian, ubuntu, debian) with different kernel versions (from 4.4.179 to 6.1.50), as well as with different versions of bluez (tried 5.43, 5.53, 5.64, 5.69). At the same time, everything works successfully on a computer with the x86_64 architecture and on a Raspberry Pi4.
I also tried Orange pi Zero2 with different OS and kernel versions.

Orange Pi 4lts:
Linux orangepi4-lts 5.18.5-rk3399
BlueZ 5.64
