unfortunately that is not possible; all GPIOs (Port A, B and C) and the GPIO used for the side button go directly to ESP32 which is powered off in shutdown mode.

The only two options (I know of) to wakeup M5Paper from shutdown mode are:

long press of side button
RTC alarm

Thanks

Hello @Krmiller

I am not able to reproduce the issue you are describing. Tested with Linux and MacOS client. That said I recommend not using delay() in the loop as it blocks the WiFi background process.

Try replacing loop with below code. (You should see a much quicker response too.)

void loop() {
  static uint32_t t = millis();

  if(millis() > t + 5000)
  {
    t = millis();
    int clientCount = WiFi.softAPgetStationNum();
    Serial.print("Connected clients: ");
    Serial.println(clientCount);
  }
}

Thanks

Hello @Pajdzian

I measure about 62 mA charging current (at the battery) when using M5Launcher and the same amount when running Cardputer UIFlow2 or Demo firmware (the one preloaded).

So I am curious: what other firmware did give you a slower charging rate?

Thanks

Hello @sqbaczek

unfortunately I don't have the proper hardware, e.g. TOF4m unit, so I cannot test this myself. Sorry.

BTW: are you aware that in UIFlow1 you use PaHUB channel 0 and 2 and in UIFlow2 you setup PaHUB channel 0 and 1.

Thanks

Hello @sqbaczek

assuming the programming is correct my best guess would be that the two ToF4m influence each other due to the signal they both send out. Maybe the signal of one gets reflected from the walls and then is picked up by both (and vice versa)?

BTW: have you tried the UIFlow2 instead? Do you get the same results?

Thanks

Hello @cryptospok

please find an example in the UIFlow2 Project Zone: M5ToughTouchTest_UIFlow2.1.7 showing how to get rid of old / duplicate touch events.

Hello @mtrehy

have you tried to connect only one of the two (M5Scale or Led Bar) to your M5Atom and see if you can make one work at the time?

Thanks

Hello @r0kh0rd

I think it has been fixed by M5Stack. Check out this example - works for me.

BTW: my example does not work anymore as M5.Lcd.getSPIinstance() no longer exists in M5CoreS3 library.

Thanks

Hello @r0kh0rd

I am not sure it is still valid, but last year I encountered a similar issue when trying to use the LCD and the SD card together with an M5CoreS3.

Maybe the solution I found at the time might be helpful for your situation as well.

Note: I cannot test this myself as I lack the necessary hardware, e.g. I do not have a LoRa868 v1.1.

Hello @soujiro0725

please find an example here.

Hello @reptilepvp

just try something like below:

label2.setText(str(((ncir2_0.get_temperature_value) * 9) / 5 + 32))

Note: untested as I do not have the necessary hardware to verify.
Thanks

Hello @reptilepvp

according to its datasheet the used sensor MLX90614 is Celsius only.

That said, there is a quite simple formula to convert Celsius into Fahrenheit. Have you tied that?

(0 °C × 9/5) + 32 = 32 °F

Thanks

Hello @Phil_C

you could also try to not define the not used GPIO, e.g. comment out those lines. Maybe that is a better approach than setting it to -1 as I suggested before.

Thanks

Hello @ivanurwin

the communication between PC and M5AtomS3U happens via native USB (without an external USB/Serial IC) which cannot be used with UIFlow2 UART blocks. UIFlow2 UART blocks define GPIOs for RX and TX (among others) which do not exist for a native USB connection.

The only UIFlow2 block I see which will read data from the PC via a native USB connection is prompt for text with message.

Thanks

Hello @Phil_C

instead of 100 for non used GPIOs have you tried -1?

Hello @Steven010

have you tried to follow the examples given in the documents listed here?

From what I can tell your modem is connected to LTE-M1 but with AT+CIICR (a command that doesn't exist for SIM7080G) you try to setup GPRS which doesn't match LTE.

Have a look at for instance the document explaining a TCP/UDP connection. I think your next command should probably be AT+CNACT=0,1 to activate a PDP and then AT+CNACT? to check for an IP address. And then go from there.

Thanks

Hello @G00TH

I think the issue is with M5Core2 library not being ready/compatible for Arduino library version 3.x.x. (I get the same compilation errors as you are reporting.)

That said, you could downgrade Arduino library to version 2.x.x - then the Hello World example of the M5Core2 library works for me.

Or I suggest you try M5Unified with M5GFX libraries instead. For me they compile and run fine with Arduino library 2.x.x or 3.x.x.

#include <M5Unified.h>
#include <M5GFX.h>

void setup() {
  auto cfg = M5.config();
  M5.begin(cfg);
  M5.Display.println("M5Core2 - Hello world");
}

void loop() {
}

Hello @scoobysnax

have you tried to push the WAKE button when M5Dial is running from battery to power on the device?

M5Dial docs are here.

Thanks

Hello @johseffer

yes. See here.

Hello @Marco-Visser

you are on the right path: PaHub unit is exactly what is needed to control multiple I2C slaves which have identical I2C addresses.

Please find an example in the UIFlow2 Project Zone: M5Dial_PaHub_2x4Relay_UIFlow2.1.6
