Hello @fkarner

hmm, since you already tried changing the modem baudrate I am at a loss what might have gone wrong.

Maybe my serial pass-through example can shed some light onto this issue?

Thanks
Felix

Hello @desmbr

hmm, yes, that doesn't look good.

Have you tried without the hat connected?

Have you tried when running from battery?

Have you tried to fully power off / on M5CoreInk? E.g.

• disconnect USB-C
• press and hold RST button in the back for 5 seconds
• turn back on via side button (or by plugging in USB-C)

Also, are you running the latest UIFlow2 v2.2.3 firmware? Maybe use M5Burner to fully erase first and then reinstall UIFlow2 v2.2.3?

Thanks
Felix

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

Hello @desmbr

I created an UIFlow2 light sleep example for M5CoreInk but I cannot confirm the display fading you are reporting.

You can find my example in the UIFlow2 ProjectZone called: M5CoreInk_LightSleep_Test_UIFlow2.2.3

Hello @konacurrents

yes, that silk screen can be a bit misleading.

There is function IrReceiver.getProtocolString() which gives you the protocol (e.g. NEC, Samsun, etc.) to use when sending a learned code. Have you tried that?

Thanks

Hello @konacurrents

by Atom's port extender do you mean M5AtomABC? If yes, the middle port is using GPIO33 and GPIO23 (not GPIO32) - see here.

Thanks
Felix

Hello @ChuckInDallas

there is a POWER SWITCH at the bottom. See here. Make sure it is in the on position to charge and/or power M5Core.

Thanks

Hello @cthulu

you want to check against ESP_SLEEP_WAKEUP_EXT0 as wake-up cause since the touch interrupt line (GPIO36) is setup using esp_sleep_enable_ext0_wakeup().

BTW: ESP_SLEEP_WAKEUP_TOUCHPAD is meant for an ESP32 feature where a GPIO can act as a touch sensor. See here (Which is different from the touch screen).

Hello @myscho151

you could use an M5StickCPlus - see stock example here.

Hello @taunushexe

please find an M5Dial RFID example reading UID and data in the UIFlow2 Project Zone: M5Dial_RFID_ReadUID_ReadData_UIFlow2.2.2

Thanks
Felix

Hi guys

please find an M5CoreS3 example in UIFlow2 Project Zone controlling a servo. It's named: M5CoreS3_Servo_Example_UIFlow2.2.2

Thanks

Hello @teastain

M5.Lcd.setBrightness() works for me.

Thanks
Felix

Hello @Johnmholmes

given that there is only one 120 Ohm resistor listed in the schematic I'd say that is the one. You should also be able to follow the traces from the resistor to the connector to confirm.

Please note: I do not have the M5Stack Mini Can unit so I cannot confirm / measure it myself.

Thanks
Felix

Hi @amateur58

you need to open the PDF of the schematic, else you don't see all of it. +5VOUT going to the Grove port comes out of U6 going through diode D20. So if you were to feed 5 V to the Grove port it would end at the diode.

Thanks
Felix

Hello @amateur58

as you already found out M5AtomS3 can be powered via 5 V through Grove. The same is true for M5NanoC6 as VBUS (from USB-C) is connected to 5 V of the Groove port.

However M5StickCPlus2 is different as it has a dedicated 5 V IN and 5 V OUT. It can only be powered via 5 V IN (which is not on the Grove port).

Thanks
Felix

Hello @myscho151

if you have access to a soldering station you could connect the INT line to a GPIO yourself. I've done that for am M5Core2 - please see here.

Thanks
Felix

Hello @sat-informatica

below code works for me:

import network

wlan = network.WLAN(network.STA_IF)
wlan.connect('SSID', 'Password')
label0.setText(str('Connecting...'))
while not (wlan.isconnected()):
  pass
label0.setText(str('Connected'))

Thanks
Felix

Hello @wsanders

I think these compiler error have been fixed (see here), but after tagging the library. I guess it will be in M5Unified 0.2.4.

Thanks
Felix

Hello @cristian-spiescu

I am sorry to hear about your troubles. The forum in mainly users helping other users. That said, there a a few M5Stack people in here as well from time to time. (BTW I am not one of them.)

Unfortunately I do not have the necessary hardware to try and help you out. Sorry.

May I suggest you try sending an email to M5Stack support - I cannot guarantee any better outcome but I think it probably doesn't hurt to try.

Thanks
Felix

Hello @SirMichael

you are absolutely correct. Overwriting the button with a rectangle only removes it from the screen, but doesn't deactivate its touch function. You would need to deactivate the touch function in addition to drawing the rectangle. Sorry I've missed that.

Thanks
Felix
