@dariuszseweryn I just tested on a Xiaomi MI9T Android 11 and same issue. Will try to dig deeper and I'll talk with the creator of the dongle to see if a firmware update can make it readable for Android.

What is your device?
Does your device pair/bond?
Does it changes services?
Could you share a full log from the beginning of connection up to the error?

@dariuszseweryn Hello, thanks for asking!
I have all in my bug:
Smartphone / tablet
Device: OnePlus 6T
OS: Android 11
Package version: 1.17.2
I sync to a N64 Bluetooth dongle successfully, no error, I can write and read every other characteristic except for that one with this library. It does changes services.

Is this the peripheral you connect your phone to?
I asked for logs, please share them but with below settings in your app — it will give more information on the internals of the library. Also timings may be important so please leave timestamps.
RxBleClient.updateLogOptions(new LogOptions.Builder()
.setLogLevel(LogConstants.VERBOSE)
.setMacAddressLogSetting(LogConstants.MAC_ADDRESS_FULL)
.setUuidsLogSetting(LogConstants.UUIDS_FULL)
.setShouldLogAttributeValues(true)
.build()
);

@dariuszseweryn Correct! I'm able to do all the operations on web with the same Android device to that dongle and with iOS. So far, only that characteristic is the one getting me an exception with this library.

I'm making the Open Source version of Android of the site: https://blueretro.io and while I access that site with the same Android, that characteristic is able to show data on my device.

If the peripheral has been paired/bonded it may be that something got off with the Android cache. Could you try reboot your phone and retry?
If that does not work, you may try to add an artificial delay between connecting and before the first operation on RxBleConnection happens as Android needs some time to re-establish the bond.

@dariuszseweryn I tested both scenarios and same issue with the same characteristic and on Web with the same device I can always get a result. I tried rebooting both devices several times, I also added from 2 to 10 seconds delays with several retries (10 retries) and same error. I did the same right after and right before that characteristic with any other characteristic and I have no issues, I can read and write the other ones, no problem. I'm never losing the connection as I can keep using and doing stuffs with the peripheral, even ms after that attempt of read call.

Could you try nRF Connect app and see if you could perform the same scenario there?

@dariuszseweryn I get the same error "Error 133 (0x85) GATT ERROR". The crazy thing is that I just tested with the Web interface using the same Android and it works. I also tested on iOS and it works:
This is Web Android (same device):
This is the error with nRF Connect (same device, other values are readable, as you can see):
This is iOS:
This is the value I'm getting on iOS/Web: [118, 49, 46, 56, 46, 51, 32, 104, 119, 49, 32, 110, 54, 52, 0, 0, 0, 0, 0, 0, 0, 0, 0]

It looks like an Android BLE stack bug. Not sure what the web API uses. We could try to dig deeper by getting your phone's BT HCI logs with both app usage and web usage and analysing them — maybe some workaround will pop-up
Edit: you could also try connecting with a different Android device if you have one
