Wifi sniffing suddenly freezes with versions > 1.6.971

cyberman54 commented 5 years ago

With software versions > v1.6.971 sudden freezes of wifi sniffing were reported and could be reproduced, but reason is unknown yet.

While wifi sniffing is freezed the device stays alive in it's other functions:

BT sniffing continues
device continues sending data via LoRaWAN
LED is functional

Perhaps not application version dependent, but caused by latest updates in ESP32 or arduino-esp32 core :-(

Issue was not again seen (yet) since upgrade to ESP-IDF 3.1.2 with paxcounter release v1.7.11

Issue was once again seen with v1.6.996 (see below), not (yet) with v1.7.x, but could be still an issue in v1.7.x -> re-openend

This issue was not seen since ESP32 core was updated. Closing.
