ATOM Lite

ricardo.pereira

Hello,

I need some help with ESP-IDF in a Atom Lite. I have two version of Atom Lite and one of Stick C.

One version of Atom Lite has a label with the text "Adding Model-ATOM-2" with FCC details, the other version has a label with text "NOTE".

See Photo: https://pasteboard.co/JlJHMAW.jpg

My program, designed with ESP-IDF, works perfect in Atom Lite with label "Adding Model-ATOM-2" and "ESP32 DevKit-C" but when I use the Atom Lite with label "NOTE" or Stick C, the wifi disconnects when registering with AP. Sometimes I can get a stable connection, but after many many tries and time.

.

Do you have any ideas to try to solve this issue?

Thanks & Regards,

To avoid possible conflicts with my app, I tested with Wifi Examples from ESP-IDF repo:
https://github.com/espressif/esp-idf/blob/master/examples/wifi/getting_started/station/main/station_example_main.c

Sorry for this missing point.
