Add TEST_ENTER/TEST_EXIT commands via BLE to enter/exit test mode. In test mode, inference results are suppressed; testers can directly trigger BLE JSON (TEST_BLE *), CAN+Buzzer actions (TEST_CAN *), or run sequenced full-coverage tests (TEST_BLE_ALL, TEST_CAN_ALL, TEST_ALL). Auto-exits after 60s idle. Routes unrecognised BLE commands through new bt_uart_set_extra_cmd_cb() hook.

/*
|
|
* bt_uart — DX-BT24 Bluetooth module UART driver
|
|
*
|
|
* The DX-BT24 is a UART-transparent BLE module. Whatever is written to the
|
|
* serial port is forwarded verbatim over BLE to the connected iOS/Android app.
|
|
*
|
|
* TX (Notify → app):
|
|
* bt_uart_send_json(json_str) — thread-safe, non-blocking queue
|
|
*
|
|
* RX (Command ← app) — handled automatically by the reader thread:
|
|
* {"command": "status_check"} → Notify: response_type=status_check
|
|
* {"command": "get_rent_status"} → Notify: response_type=rent_status
|
|
* {"command": "rent"} → status 0→1; Notify: rent_status
|
|
* {"command": "return"} → status 1→0; Notify: rent_status
|
|
*
|
|
* Usage:
|
|
* bt_uart_init("/dev/ttyS1", 0)
|
|
* bt_uart_set_identity("1.0.0", "BT-24")
|
|
* bt_uart_set_intervention_cb(my_fn) // optional
|
|
* bt_uart_send_json(json_str)
|
|
* bt_uart_close()
|
