![]() Current code stopped inquiry if major class is not Phone. Modified the condition to consider for both Phone and Audio to cover majority of real world devices. Closes https://github.com/espressif/esp-idf/issues/6548 |

ESP-IDF BT-INQUIRY demo
Demo of Classic Bluetooth Device and Service Discovery This is the demo for user to use ESP_APIs to perform inquiry to search for a target device and then performs service search via SDP.
How to use example
Hardware Required
This example is designed to run on commonly available ESP32 development board, e.g. ESP32-DevKitC.
Configure the project
idf.py menuconfig
Build and Flash
Build the project and flash it to the board, then run monitor tool to view serial output:
idf.py -p PORT flash monitor
(Replace PORT with the name of the serial port to use.)
(To exit the serial monitor, type Ctrl-]
.)
See the Getting Started Guide for full steps to configure and use ESP-IDF to build projects.
Example Description
After the program started, the device will start inquiry to search for a device with Major device type "PHONE" in the Class of Device Field. Then it will cancel the inquiry and started to perform service discovering on this remote device.
Trouble shooting
-
Some old BT device doesn't place their device name in EIR, but new devices place their device name in EIR. Users can obtain the peer device name in
bt_app_gap_cb
ESP_BT_GAP_DISC_RES_EVT
event handler or resolve it in EIR just like the functionget_name_from_eir
does. -
ESP32 places its device name in EIR by default.
