m5dial: wifi not work when rfid is enabled

studiosacchetti

even a simple code like this can raise my problem

//connect to WiFi 
Serial.printf("Connecting to %s ", ssid);
WiFi.begin(ssid, password); 
while (WiFi.status() != WL_CONNECTED) { 
delay(500); Serial.print(".");
 }

Serial.println(" CONNECTED");

with this config setting everything is ok

M5Dial.begin(cfg, false, false);

but if i enable rfid

M5Dial.begin(cfg, false, true);

m5dial can connect only once to my wifi network, i have a fritzbox router

any idea?

@studiosacchetti Did you ever solve this issue? I am now having exactly the same issue.

The RFID module might be interfering with the WiFi signal. Try using a different power source or check if the RFID is drawing too much current and test with a different router or 2.4GHz channel.

@Slarck Thanks will look into those. I don't need them simultaneously, I tried turning the RFID on/off, but once I turn it on (after doing a server packet test), even if I turned it off Wifi still doesn't work.

@Slarck So I have hooked up a 12V power supply to the power connector (2pin green). It doesn't help, I can't connect to the Wifi when the RFID is enabled.

Any ideas? I tried turning the RFID off when I connect to the wifi

M5Dial.begin(cfg, true, false); // enable encoder, disenable RFID

but once I turn on the RFID, it doesn't seem that turning it off enables the Wifi.

If I never enable the RFID, then I can connect to the Router, so I don't think my router or channel is an issue.

Any other ideas welcome.

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
