Hopefully someone of you can help me in my current project.
We are using ESP-IDF on the current stable version 4.0.1 with ESP-AZURE to send telemetry data to the Azure IoT Hub.
I have my main loop which uses the light sleep mode and configured the wifi with power safe mode with the following line:
Code: Select all
esp_wifi_set_ps(WIFI_PS_MAX_MODEM);
Do I have to necessarily need to STOP and START the WIFI before light sleep and after light sleep?
Right now I'm having a main-loop which starts the light-sleep after 5 seconds for 5 seconds.
I've several tasks which are running all the time. One tasks sends my generated telemetry messages to IoT Hub (so uses the WIFI) with a periodically call to
Code: Select all

After this happened a few times following error is printed:

This only happens with light sleep mode. If I'm commenting out the light sleep, the error seems to be disappeared.
I really need to get this done, thanks in advance!
