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.
• Devices used till now are Xiaomi (Redmi 7 - Android Pie), Samsung A7 (Oreo)

Please guide us on relevant APIs, permission sets required if any.

These two statements stand out to me. You tried other Android devices with the same result. When you looked into the limit of devices that can be paired, was that for the protocol in general or for Android? It's possible Android has a built in limitation at the OS level.

Welcome to Android Central! It does look like an inherent limitation: https://stackoverflow.com/questions...nded-i-e-paired-devices-for-bluetooth-le-devi

And the purpose of all this pairing is for what reason? Is this something like Verizon claiming. If you buy their 1 Gigabit service - you can connect up to 100 devices. <--- If anybody tests this claim - Please report results in the Verizon FiOS forum. Thank you!

The Purpose is to connect as many bluetooth devices (connected to meters).
