Hello @GMG

care to share some code which exhibits the issue you are describing?

Thanks
Felix

Hello @jackchan000

ok, for some reason GPIO0 is held low causing the ESP32 starting up into download mode. GPIO0 is controlled by the USB serial chip inside M5Paper which in turn is controlled from the USB driver. (There is nothing much you can do to change that except maybe try a different computer.)

Try to power off and power on your M5Paper with the following steps:

disconnect USB press button in the back (this should power it off) Note: there is no visible change on the screen when doing that. press middle button on the side (this should power on M5Paper and run the factory test)

Note: the button in the back has two functions depending on whether M5Paper is connected to USB or not.

reset (USB connected) power off (USB not connected)

Thanks
Felix

@paopao Hi! If using UIFlow, then this is it, if it‘s Arduino. Serial port sending commands
or use API， then CH_index = 1

@dsrc12 Hi! This must be outdoors in wide-open areas, cold start time takes about 3 / 4 minutes

@lishengkkk Hi there, please check if the baud rate of both sides match (you can also try to change the baud rate, such as the common 115200). If it's a UART via separate wiring. Please make sure TX RX is connected correctly.

Hi there We appreciate your feedback! but so far there is no demo provided

Here's how i shut down the OV3660 lens....

// Put Camera Module into Standby Mode sensor_t * s = esp_camera_sensor_get(); s->set_reg(s,0x3008,0xff,0x01);//banksel --- ? Is this needed for ov3660? Is there only 1 bank delay(100); s->set_reg(s,0x3008,0xff,0x80);//reset (we do this to clear the sensor registries, it seems to get more consistent images this way) delay(100); s->set_reg(s,0x3008,0xff,0x40); //stand by (sensor, register, mask, value) delay(100);

I reboot the camera to turn the lens back on.. .but there are registry setting that can be invoked to restart the camera module. see Omnivision OV3360 spec for registry settings.

Hello @Hafenstrand

ok, I see. Unfortunately I don't think that 5 days (= 120 h) is achievable with the TailBat's 190 mAh capacity. Measuring the power consumption of the M5Atom in deep sleep I get about 11 mA (at 5V). However with 190 mAh in the TailBat you'd need to get the current in deep sleep mode down to about 1.6 mA.

BTW: 1 mA is consumed by the RGB LED even if it is off. I assume the rest is consumed by the USB and 3.3 V converter chip inside the M5Atom.

Thanks

You might look at ESPnow to send the values over Wi-Fi. The setup is pretty simple.

@alpinerobotics desktop IDE is not currently supported and so out of date.

What are the WiFi issue you have?
The firmware does not like spaces in SSID’s

@felmue I found the M024 M-BUS Connection proto board. It looks like the bus is available on two rows. I think this is the thing to use for connecting to the bus.

Hello @felmue ,

In fact I received answer from M5 support in the morning. I managed to solder the cable to the right place and now fan works. Thank you for your help!

M5Paper

Hello!

It depends on the accuracy of the 3D Printer.
M5 Paper requires high accuracy.
You need a high-precision printer.
The accuracy of the printer for amateurs is about 0.4mm width.
I think it is impossible because the accuracy is low.

The controller would need to be mounted outside where it won’t suffer from atmospheric changes. The Atom or the stamp will work if you just want to read a sensor and send MQTT messages to a server. What “wet” zone thermistors have you looked at? And as to monitoring rhe compressor, you could even get away with a microphone if the compressor is not also damp.
