BLE cannot connect to virtual device broadcast by Android app nRFConnect. (IDFGH-7404)

Zmmfly commented 2 years ago

Environment

Module or chip used: [ESP32-WROVER-I]
IDF version (run git describe --tags to find it): // v4.4.1
Build System: idf.py
Compiler version (run xtensa-esp32-elf-gcc --version to find it): // xtensa-esp32-elf-gcc (crosstool-NG esp-2021r2-patch3) 8.4.0
Operating System: [Windows]
(Windows only) environment type: [Plain Command Prompt].
Using an IDE?: [No]
Power Supply: [external 3.3V]

Problem Description

//Detailed problem description goes here. WiFi SoftAP is turned on, BLE is also turned on at the same time, scanning is normal. The connection to the actual device is normal, and the connection to the virtual device broadcast by nRFConnect reports a connection timeout error, and the nRF sniffer does not find the connection initiation packet.

Expected Behavior

The nRF sniffer should see connection initiation packets and the connection is fine.

Actual Behavior

There is no connection to initiate a data packet, and the GAP event reports a connection timeout error (BLE_HS_ETIMEOUT).

Steps to reproduce

Broadcast the virtual device from nRFConnect
Enable WiFi SoftAP and Bluetooth scanning on ESP32 at the same time
Attempt to connect to the virtual device broadcast by nRFConnect
GAP event will report connection timeout error

Code to reproduce this issue

Sorry, these are private codes.

In the current test, there is no problem connecting to the physical device, and the connection to the virtual device broadcasted by the mobile phone App nRF connect will not send a connection packet, why?

Zmmfly commented 2 years ago

I'm so sorry, I reopened this issue because it's very inconvenient to debug without being able to connect to a virtual device.
