@veryalien Thanks veryalien for responding on the ESP-NOW support. Sorry for the late reply too! I did see that the M5Dials and the TAB5 support UDP/TCP which I will look into after I get the current project up for now. Thanks-Brian

@teastain hello just wondering is the screen going to be off the entire while doing this? and im wondering how do i reset the firmware with it bricked and the screen off? ive consitently tried the button thing and plugging in at same time, maybe not getting it right idk. im on linux (chromebook) and i got the burner unzipped loaded up and i couldnt get the cardputer to go onto the os files system i could only find it through port and in the linux usb sharing. so i instead tried to download the firmware onto the local machine and then to the device in thw port and then it turned off when i did it. did i add one firmware o to the other making it brick or crash or just sent to cardputer bad?

this should go as reply to https://community.m5stack.com/topic/1838/ncir-unit-weird-values accidentally posted as new topic.

@robski Yes it happens only when relay is called to be on not in standby Unit 4relay is connected to Port A with his supply(5V), but I using +24vdc for supplied m5dial

@robski You are right. I now use pin 33. All sensors keep updating. Now i have to built a relay cirquit for our 230volt net. Thanks!

@galehill The "5mm" holes, actually 4.85mm, are for Lego pegs to attach the Atomic base to Lego Technic parts like beams. Most M5stack things have Lego-compatible mounting points. If you look under the Atom Lite, there's a small yellow M2 hole marked on the label which you can use to fix the atom to the atomic base from below. There's a M2-sized hole in the atomic base. Just screw through the atomic base from below, into the atom label and there's a thread inside. M5stack used to supply a M2 hex-headed bolt of the correct length and a little Allen key to mount the atom on the base. But usually just mounting the atom on the atomic base pins is enough for most uses.

Hello @drvval when I run M5Core2 v1.1 from battery, power consumption gets down to about 5.2 mA @ 4.2 V in ESP32 deep sleep. BTW: Interestingly when running from battery I can turn off the boost circuit. In my test I now only turn LCD backlight to zero and turn off boost circuit. When I turn LCD and/or TP off things start to go wrong. My guess is that ESP32 SPI / I2C bus gets confused if devices are suddenly disappearing. Thanks Felix

@kuriko 试了2.4.2现在没有问题

To anyone trying something similar in the future MODULE_4IN8OUT module; MFRC522_I2C mfrc522(0x28, -1, &Wire); void setup() { M5.begin(true, true, true, true); Serial.begin(115200); delay(500); Serial.println("Starting setup..."); M5.Lcd.println("Init..."); // POWER MANAGEMENT dla Port A (RFID) M5.Axp.SetBusPowerMode(0); M5.Axp.SetLDOEnable(2, true); delay(200); // --- I2C BUSES --- Wire.begin(32, 33, 100000); Wire1.begin(21, 22, 100000); delay(100); M5.Lcd.println("Init 4IN8OUT..."); // Start module 4IN8OUT if (!module.begin(&Wire1, 21, 22, MODULE_4IN8OUT_ADDR)) { M5.Lcd.setTextColor(RED); M5.Lcd.println("4IN8OUT INIT FAIL"); Serial.println("4IN8OUT INIT FAIL"); while (1) delay(1000); } M5.Lcd.setTextColor(GREEN); M5.Lcd.println("4IN8OUT OK!"); Serial.println("4IN8OUT OK!"); M5.Lcd.setTextColor(WHITE); // Init RFID mfrc522.PCD_Init(); M5.Lcd.println("RFID OK!"); Serial.println("RFID OK!");

Hi, @aliense44. I have a Card Computer ADV, a GPS/LoRa module, and an ENV III Sensor. I was trying to test the ENV Monitor ADV app, but it didn't display any information. Could you tell me how to connect it for it to work with the app? Thank you.
