Hello,
I have 2 M5Atom Matrix since the beginning of the year, all my tests used only one. After trying uiflow, I started to have wifi connection issues: my board never connected to Wifi anymore.
Back to PlatformIO, same issue
Back to Arduino, even with the "WifiClient" example, same issue, suck when trying to connect. However, the "WifiScan" sketch is working fine.
I tried to erase the chip, and try also the second board, same issue!
I verified my access point which is "WPA2-PSK / AES", channel 6 (not exotic). I tried a second access point using my phone. no success...
any clue?
Regards,
Manumane.
