stm32wb BLE client to server connection time too long

[Mtopa.1]

Hello everyone.

I have a question about the STM32WB BLE. I set one device as a server and the other device as a client. In order for the devices to communicate in ST's own software, the client device needs to know the service and characteristic features of the server device. I have run instances of ST but the connection time is too long. Therefore, I made a connection on the address without scanning directly. The connection was made quickly, but it took a long time to receive the service and characteristics. Is there a way to get service and characteristics faster?

I am using the following function

aci_gatt_disc_all_primary_services();
