Is there support for GATT caching in softdevice S132_nrf52_7.2.0_softdevice.hex?

[Andres]

My current product uses an NRF52832 with SDK 13.0 and s132_nrf52_4.0.5

I was asked to implement GATT caching to speed up the connection time with a mobile phone.

I know GATT caching is a feature of Bluetooth 5.1

I also know that the most recent softdevice s132_nrf52_7.2.0_softdevice.hex supports Buetooth 5.1

My question is:

Does the softdevice s132_nrf52_7.2.0_softdevice.hex can support GATT caching?

In other words, if I update my firmware to use softdevice s132_nrf52_7.2.0_softdevice.hex and SDK 17.1.0 will I be able to implement GATT caching?

Any suggestions?

Thank you.

No.

Any suggestions?

I have noticed that most phones will cache the database of previous connected peers if you don't enable service changed characteristic. Have you tried this?
