#748

[law-ko]

@shubhamdp any idea on this?

[shubhamdp]

@law-ko Is this with PSRAM?

[law-ko]

@law-ko Is this with PSRAM?

@shubhamdp Yes, both BLE and Matter is on PSRAM

[pimpalemahesh]

@law-ko Could you please share the logs since bootup and sdkconfig file? Also, is it possible to provide the minimum possible patch on the ESP-Matter light example that can help us to reproduce the current issue?

[shubhamdp]

@law-ko We are unable to reproduce this. Can you please let us know the frequency of occurrence of this.

Please share the sdkconfig file for the project.

[pimpalemahesh]

@law-ko I attempted to reproduce this issue many times but was unable to do so.

Please use this patch to help us narrow down the cause of the crash: esp32(9d81f09).zip

1. Unzip the attached file.
2. Replace the libbtdm_app.a file in components/bt/controller/lib_esp32/esp32/.
3. Apply the patch 0001-add-for-bt-sleep-debug.patch to the IDF.

This should assist in further debugging the issue.

Please enable the debug logging mode and share complete logs.
