Hi, I have 2 questions: the api for L2CAP is only for BLE or can also work for BR/EDR? (currently didn't manage to connect with BR/EDR) I use https://github.com/bluekitchen/CBL2CAPChannel-Demo on iPhone with le_credit_based_flow_control_mode from blue kitchen and the throughput was very low. I also tried to use L2TEST from Bluez (which uses L2CAP BASIC MODE) but it failed to connect Can anybody help how to increase throughput? The best result I received was 18 kilobyte/second. Thank you
