If you just need the API Key, just connect it to your computer, open M5Burner, and select “configurate” button under the AtomMatrix firmware, select the serial port atom matrix is connected to, and it will show your API key on the next screen. To get to AP mode you need to plug in/turn on the atom while holding the button under the matrix until it turns yellow.

Thank you very much for the info and code! But the reason I need to send a start command is because the microphone decoder only sends code after a start condition is sent, and I'm not sure that it is sent automatically.

I am trying to get the CoreS3's proximity and ambient light sensor to work in UiFlow2.0 and I am having these problems.
1: i2c "Generate START condition" block shows this error "OSError: I2C operation not supported"
2: i2c "Scan Device" block returns addresses, but the address for the LTR553 (0x23) does not show up.
3: You need an object with buffer protocol to send data via i2c but something with buffer protocol (like bytearray) does not work.

Any help or bug fix/update is much appreciated!

I modified my Push6060 to be 500mm tall, and I swapped the stepper motor, but now when I send an RS485 command, the blue light dimly flashes, and it does not do anything. Even when i query its current position, or ID, it returns "None". (I am using an ISO485 for interface) . Does anyone know why this would be happening?

I cant import M5F files for core, core2 or paper devices, simply saying that their not supported. This bug mainly happens on mobile devices (Apple iPad 7th generation, Safari browser) and is hard to replicate on PC.

So it can’t receive data, right?

Can the RCA unit receive data as well as transmit? I noticed a few extra components on the board that might prevent it from doing so.

I made a Custom Block that does this!
