ESP32S2 WiFI connection problems
Posted: Wed Jun 09, 2021 1:33 pm
Hi,
I have problems with WiFi connection on boards with ESP32S2. I have two types of ESP boards, Espressif ESP32-S2-Saola-1R and my own boards (custom design). I use fresh version of Micropython GENERIC-S2 (clone from Github) compiled with IDF 4.3. All technologies that need SPI, I2C, GPIO inputs/outpust work well, but I have problems with Wifi comunication. Connection to wifi works fine, but subsequent communication does not work.
Simple log with upip install for example :
connecting to network...
network config: ('192.168.1.109', '255.255.255.0', '192.168.1.1', '192.168.1.1')
7c:df:a1:17:a9:b8
Installing to: /lib/
Error: Unable to resolve micropython.org (no Internet?)
on all my ESP8266, ESP32 boards the same code works fine
Do you have any idea, please ???
