Description
Answers checklist.
- I have read the documentation ESP-IDF Programming Guide and the issue is not addressed there.
- I have updated my IDF branch (master or release) to the latest version and checked that the issue is present there.
- I have searched the issue tracker for a similar issue and not found a similar issue.
IDF version.
5.4.1, 5.3.2
Espressif SoC revision.
ESP32
Operating System used.
Linux
How did you build your project?
Command line with idf.py
If you are using Windows, please specify command line type.
None
Development Kit.
custom board
Power Supply used.
External 3.3V
What is the expected behavior?
Using either of the two examples:
- esp-idf/examples/bluetooth/esp_hid_device/ (using the esp_hid component)
- esp-idf/examples/bluetooth/bluedroid/classic_bt/bt_hid_mouse_device (using the bluedroid native apis)
I expect to be able to connect to the demo device from my desktop or my phone. => this works
I expect that I can disconnect cleanly and see it visible for reconnection again => this works
I expect to be able to connect to the demo device from a DIFFERNT device => this does NOT work.
What is the actual behavior?
When the new device attempts to connect, SSP proceeds as normal, but after the pin confirmation, I receive "failed to connect" style messages from my phone/desktop.
The demo code is failing with:
I (33809) HID_DEV_BT: DISCONNECT OK

The exact details differ depending on whether I "forget" or not, but it always ends up with the hidd_l2cif_connect_ind: incoming connections from different device, rejecting message.
With GDB I can see that even after disconnecting, the hd_cb.device object STILL says "in_use" and has the "old" bd address:
(gdb) p /x hd_cb.device
$5 = {in_use = 0x1, addr = {0xf4, 0xa4, 0x75, 0x36, 0x2b, 0x70}, state = 0x0, conn = {conn_state = 0x0, conn_flags = 0x1e, ctrl_id = 0x3, ctrl_cid = 0x0, intr_cid = 0x0, rem_mtu_size = 0x40,
disc_reason = 0x0, timer_entry = {p_next = 0x0, p_prev = 0x0, p_cback = 0x0, ticks = 0x0, ticks_initial = 0x0, param = 0x0, data = 0x0, event = 0x0, in_use = 0x0}}, boot_mode = 0x0,
idle_time = 0x0}
This is why it then fails in hidd_l2cif_connect_ind with the inuse/address check.
It doesn't matter whether I connect first with linux/android, it just seems like it never gets torn down properly?
I've tried manually adding a call to esp_bt_hid_device_disconnect in the bt_app_task_shut_down but that just complains about the device is already disconnected.
Steps to reproduce.
I'm using bluetooth classic only so this sdkconfig.defaults is suitable:
CONFIG_BT_ENABLED=y
CONFIG_BT_CLASSIC_ENABLED=y
CONFIG_BT_HID_ENABLED=y
CONFIG_BT_HID_DEVICE_ENABLED=y
CONFIG_BT_BLE_ENABLED=n
CONFIG_BTDM_CTRL_MODE_BR_EDR_ONLY=y
