How do non windows users get the firmware on our m5's?

@dimi Nice start but how do we include other libraries so we can interface to other systems over http/mqtt/etc?

What about M5Burner for Mac OS ? Are you going to release it in the future?
Thanks

All flashes OK and detects the network OK but after the reset and the long press of "upload" it will not reconnect to the WiFi network ??? any one any ideas?
Thanks

@ajb2k3 You can burn the firmware via M5Burner
Here is the article guide you for burning

@fab Thanks gay

@gadjet Is that problem exiting still? Try to reset your board again. Sometime, it is a problem about LAN network

To everyone:
Please download lastest version of M5Burner from official website

Following the video on an OSX 10.12.6 using python 3.7 but getting the following when trying to connect.

Traceback (most recent call last):
File "./tools/esptool.py", line 2853, in <module>
_main()
File "./tools/esptool.py", line 2846, in _main
main()
File "./tools/esptool.py", line 2554, in main
esp.connect(args.before)
File "./tools/esptool.py", line 446, in connect
last_error = self._connect_attempt(mode=mode, esp32r0_delay=False)
File "./tools/esptool.py", line 405, in _connect_attempt
self._setRTS(True) # EN=LOW, chip in reset
File "./tools/esptool.py", line 377, in _setRTS
self._port.setDTR(self._port.dtr)
AttributeError: 'Serial' object has no attribute 'dtr'

However arduino is connecting with no trouble??

@cpyarger it basically runs microPython so you can import any module supported by micro python.

For example to connect to a wifi hotspot you can import the "network" module:
https://docs.micropython.org/en/latest/esp8266/quickref.html#networking

To upload custom files/modules you can use "adafruit ampy" or any of the other tools described in this tutorial: https://learn.adafruit.com/micropython-basics-load-files-and-run-code/overview
just make sure you upload them to the /flash/ folder.

Another useful thing is the REPL which allows you to see the MicroPython Log, very useful to debug your code and see what's happening in the background as not everything can be seen in the LCD:
https://docs.micropython.org/en/latest/wipy/tutorial/repl.html

The ESP32 also supports the WebREPL:
