hi
when i use the ble of bl602, it give me an error which have a bt_hci_cmd_send_sync! The error as follow:

k_sem_take timeout with opcode 0x0406, bt_hci_cmd_send_sync
bt_assert, ra = 0x2301ed34
, bt_assert
vAssertCalled
exception_entry
mcause=38000003
mepc:23034aa0
mtval:00000000
Breakpoint

I don't know, where it is from! My app code or the ble stack? Can you give a suggestion? thanks!

Use the addr2line tool to check the filename and line number of the source code corresponding to mepc:23034aa0.

How did this problem occur? Can you provide the minimum amount of code to reproduce it?

I suspect you called the bt_conn_disconnect(0x0406) API. bt_conn_disconnect / set_adv_enable SHALL NOT be called in task context or timer context.
#define BT_HCI_OP_DISCONNECT BT_OP(BT_OGF_LINK_CTRL, 0x0006)
