@arzaman said in M5stick-C connected but not reachable from UIflow:

Also mine now up and running !
thanks to M5 stack support

hope it will remain stable

The problem is down to the server host, every so often the server has a fit and brakes things.

@arzaman Just upload an arduino program in the normal way. It will overwrite the UIFlow bootloader and you can continue to use the devices.

/* This example shows how to take simple range measurements with the VL53L1X. The range readings are in units of mm. */ #include <Wire.h> #include <VL53L1X.h> VL53L1X sensor; void setup() { Serial.begin(115200); //Wire.begin(); Wire.begin(25, 13); // (SDA, SCL) grove stick //Wire.begin(21, 22); // (SDA, SCL) grove stack Wire.setClock(400000); // use 400 kHz I2C sensor.setTimeout(500); if (!sensor.init()) { Serial.println("Failed to detect and initialize sensor!"); while (1); } // Use long distance mode and allow up to 50000 us (50 ms) for a measurement. // You can change these settings to adjust the performance of the sensor, but // the minimum timing budget is 20 ms for short distance mode and 33 ms for // medium and long distance modes. See the VL53L1X datasheet for more // information on range and timing limits. sensor.setDistanceMode(VL53L1X::Long); sensor.setMeasurementTimingBudget(50000); // Start continuous readings at a rate of one measurement every 50 ms (the // inter-measurement period). This period should be at least as long as the // timing budget. sensor.startContinuous(50); } void loop() { //Serial.print(sensor.read()); //MM Serial.print(sensor.read()/10); //CM if (sensor.timeoutOccurred()) { Serial.print(" TIMEOUT"); } Serial.println(); }

it works!!!

Glad it works and sorry for posting the pins the wrong way around.

@watson said in M5Stick FRIED:

@ajb2k3 Looks like Voltage regulator chip - 5v to 3.3v

Triode is smaller than it.

Thanks @watson

@smrtokvitek just use some 3V3 regulator to step down the voltage from M5Stick and connect data lines directly. As you said, the data pins all connect directly to esp32.

@mocm You can talk with eggfly by github.

Does it do the same with the USB lead plugged it?
It could be that the battery isn't charged enough.

to reconnect, Plug the usb into a battery or laptop to power on and start charging the M5, When it beeps the main menu will briefly pop up, you hit to hit button C (right button) as soon as the screen appears this will send you to the wifi screen and you use c button to move do to the "reconnect to uiflow" option then hit the middle (B) button to connect.
Go into UIFlow and hit the circle symbol next to (disconnected) to reconnect to the M5 (Sometime it will auto connect and say connected in green).

m5stick grove is different, pin is gnd, vcc, 25, 13, those can be viewed from the back of the stick
