Hello @gadgetguy
I can confirm that enabling RFID prevents M5Dial from connecting to WiFi.
After enabling RFID in M5Dial.begin(cfg, true, true), try M5Dial.Rfid.PCD_AntennaOff() to temporarily disable RFID while using WiFi, then after disconnecting from WiFi enable RFID again with M5Dial.Rfid.PCD_AntennaOn().
Thanks
Felix
