How can I use my Android Phones to remember more than 200 Paired Bluetooth devices?

• Our In house app communicates with Bluetooth device (In house) via an Android Phone.
• We require a device (Android) to store pairing information for more than 200 devices (Bluetooth)
• Currently, we are losing the pairing information in our devices (Android) after more than 100 devices are paired.
* The paired device name is not lost but it asks for re-pairing.
* If we cancel the pairing request, the Bluetooth device un–pairs with Android (device).
• We have conducted the same test with various Android devices and the same issue happens.
• We have googled various forums and observed that there is practically no limit for Bluetooth devices to be paired.
* We need your help to solve the issue so that our device can remember pairing information for more than 200 devices.
• If any custom app could be developed to persistently store pairing info locally, outside Android default file system and further to be read from there while connecting the device.
• Currently used phones are Xiaomi Redmi 7 (Pie) and Samsung A7 (Oreo).

No. I did not pair those devices through my app. The app role comes in when all devices are paired. I am facing issue when I pair all the devices using the Android Bluetooth it only remembers 100 devices pairing info and not more than that.
