Hello everyone
I am using Nrf5340 Zephyr sdk v2.4.2 to broadcast BLE as a peripheral connecting 2 devices with Esp32 as central and phone at the same time, the following error occurs:
<wrn> bt_att: bt_att_recv: Unhandled ATT code 0x1b
But if I only connect to 1 Esp32 device or phone, the above error does not occur
I noticed that when connecting two devices at the same time, device 1 (Phone) will connect faster than device 2 (Esp32), is there any way to increase the connection speed
