@DarshanAtwal As long as you know how to program in micropython You can still use programs like Thonny to program directly.

@DarshanAtwal Use the latest version of UIFlow2 is its just a graphical front ent to Micropython.
There is a console mode in UIFlow2 to directly access the Micropython or you can use a program to directly access Micropython.

@sistar_hh 1
This is normal, as download premaritally set the program to start on boot.
To reset you have to use M5Burner to change the boot configuration.

Yes, OTA only work in test mode (the "> Run" button if you download, wifi is not activated an you will need to manually activate the wifi interface and connect to the target wifi.

@Jules-Vern-Hacker-Man A linux version has been built for the CoreS3 so you may want to look at that but,
The cardputer uses a Microcrontroller not a computer so you will be struggling.

@figgalicous The desktop IDE hasn't been updated in a while. The Web version gets updated weekly.

I'm testing the ENVPro and M5Station for a video guide but between 30 mins and an hour the Station resets with the rolling error log:

E (2903049) mqtt_client: Error create mqtt task
E (2918550) mqtt_client: esp_mqtt_set_config(415): Memory exhausted
E (2918551) event: event_loop was NULL

A fatal error occurred. The crash dump printed below may be used to help
determine what caused it. If you are not already running the most recent
version of MicroPython, consider upgrading. New versions often fix bugs.

I've tried enabling gc (garbage collection) to clear the memory each loop but it make no difference and if you check out my code I don't have any MQTT function enabled!

I'm at a loss here and wondering if this is a firmware issue.

@mgrouch There is already 2 I2c extenders

@desmbr If you want data to remain visible after shutdown or sleep, you do as you have surmised have to trigger the Screen HV, write the data then shut down.
The fading without the set screen HV is normal.

@chpaaa1 You will need to rebuild the firmware from scratch as the ESP32's in the Echo and S3 are not the same.
There are enough hardware differences that make them incompatible.

@kuriko ESPtool is a nightmare to use, I know I have tried. We need an Arm64 port for the Raspberry Pi

@xter-pokemon Allways erase before burning, and triple check you have the correct version of the firmware for the correct controller version.

@lenswerks You have plugged in the 2 X 12 volt batteries and turned the base on?

@lenswerks Strange behaviour.
Use M5Burner to erase and burn the latest lidarbot firmware.

@paulasousa it may be a cause of code changes in the libraries. You need to check the documents for the update records.
Probably better to rebuild from scratch

@alkaline64 have you checked the data sheet for the IMU?

@CornStarchTech yes, if you don’t put it in in the correct rotation it is a pain. I took mine apart for a guide video and never again

@anubisdarkwatch did you erase the cardputer first?
You always have to erase or you corrupt the firmware

@anubisdarkwatch have you fully charged the battery?

Use M5Burner to erase the firmware and burn the correct UIFlow version for the stick

@rgsteele No, that all I can think off, you need to contact the person you brought it from for a replacement.
