ESP_hosted-NG: ESP32 panic'ed because of illegal instruction executed in libbtdm_app.a

[franziskanerda]

Dear,

We found out an issue that is being triggered sporadically when we have WiFi and BT communication ongoing simultaneously for a longer time.

This is a tail of a log file obtained from ESP32 side:

Rebooting...

Further investigation pointed out that it might be a known bug in libbtdm_app.a already resolved with this commit: https://github.com/espressif/esp-idf/commit/a83b16f18d78c29a99a3cd57f223f9eaa2200055

Could you please provide an update of the current FW sources that includes newer library with the changes that resolve this issue?
