@bluecobras09 you need to reserch how it communicates and if there is a Micropython library for it and if not you need to learn how to create a library

Hello @Bbjodel

ok, I see. Have you looked at the debut output? Are there any errors?

Thanks

You device is not connected to your local network or it has failed to connect to the UIFLow server.
Open M5Burner, open config and check your SSID and password are correct.

Hello @Bbjodel

in order for two SPI slaves to work their CS needs to be connected to different GPIOs. See here.

I’m running esptool3.3.2-dev on mine

When the coreS3 is in boot loader mode, the port is called usb modem, when in UIFlow mode the port is called uiflow

On my computer it does take a while for the CoreS3 to be erased before flashing

Hello @toonny

try using M5Burner to either erase flash first or use the Configure button to disable LTE usage.

Thanks

You need to erase the firmware first before burning.
Please don’t double post

@flex dumb question but caught me out, you did release the button after the green light came on?

For the S3 Generation you need to hold down a button for several second to get it into boot mode, M5Burner will report a new port detected and then you can try accessing the settings.

Hello @PaulChainKang

there was a discussion a while ago about WiFi and poor RSSI.

Thanks
