3.1.5 IDF Classic Bluetooth request connection problem

Postby h1223905097 » Fri Nov 20, 2020 9:46 am

IDF version 3.1.5, when I use ESP32 Classic Bluetooth as HID HOST to request to connect to the keyboard, when the L2CAP layer sends out a creation connect request, nothing is reflected until the 60 seconds timeout set by L2CAP is used up and the timeout is returned. I searched the last packet sent by the HCI layer to the controller, and there is no problem. But I use the same procedure to connect one of my bluetooth controllers but it can connect
