Environment
Problem Description
when I change remote_filter_xxx_uuid from 16bit to 128bit , in gatt_client example: I found that when esp32 connect to the remote ble client, it will read a lot attribute It wastes a little long time(about 400ms, 20~30 times communicate event ) to do this,
Expected Behavior
after connected, read or write the service,characteristic, which already know.
Actual Behavior
after connected, send a lot read request, then read and write service or characteristic.
issues
How to speed up the communication after connected? How to change the request UUID to user define UUID ? my periperal don't have uuid 16bit.
