M5Atom Matrix and micropython
-
The Problem
I just flashed a vanilla micropython for esp32 on the M5Atom matrix. There seems to be an issue with network. I can connect to it, enter REPL and play with micropython. However if I try to turn the RF part on, the chip reboots. The reason being a power-on reboot.
An example is:
import network # Ok
wlan = network.wlan(network.STA_IF) # Ok
wlan.active(True) # Reboot on the matrixI also have an M5Atom Lite and I have no problem using either the WiFi or the Bluetooth modules with micropython
The question
Is my M5Atom Matrix faulty, or is there a problem with micropython?

let me test with mine and get back to you

I use micropython for esp32 generic http://micropython.org/resources/firmware/esp32-idf3-20191220-v1.12.bin
Wifi and repl s working on my atom lite and matrix. -
I just tried with another cable: the microcontroller works with a very short cable or from a powered hub. Basically it reboots because of a brown-out due to a power consumption that is at the limit of what a plain usb port can deliver.
