I am using the STM32 Iot Node discovery kit, and I frequently get ES_WIFI_STATUS_UNEXPECTED_CLOSED_SOCKET errors. The wifi reports it is still connected, but obviously there is an issue..
How do I properly handle this error and establish a good connection again?
disconnect and re-connect the wifi?
Soft reset the wifi module?
Hard reset the wifi module?
Something else?
The error occurs frequently and is from
en.fp-cld-azure/STM32CubeFunctionPack_AZURE1_V4.0.1/Drivers/BSP/Components/es_wifi/es_wifi.c:1843
I also frequently get
en.fp-cld-azure/STM32CubeFunctionPack_AZURE1_V4.0.1/Drivers/BSP/Components/es_wifi/es_wifi.c:1976 :AT_RequestReceiveData failed
and I don't know how to handle it
