Hi,
For one of the development, we are using ESP32. We have made our custom board using ESP32.
We are using ESP-IDF V3.3 For our project.
We are using WIFI STA Mode, BLE and HTTP to send data over cloud. BLE is only to set ssid and password of Wifi STA.
During our testing we have found that , WIFI STA has beed disconnected from WFI AP / Network Automatically and IP was 0.0.0.0. After this incident it is not able to connect again to WIFI AP / Network, and not able to get IP.
Kindly find below logs we are getting during this issue.
Here with debug log:
