  @keptan We managed to fix it simply holding down button A and reset button until Arduino ide attempted to connect then releasing it and allowing it to upload without a chance for the old code to run

  @scotts Hi Scott, I'm pretty sure that was just added as another possible fix.... without intending to suggest that there was anything wrong with your solution.... indeed I am about to follow your suggestion and add a ceramic cap to a proto board. Here's another approach again... very creative and neat. This is from the highly recommended macsbug website: https://macsbug.wordpress.com/2018/01/09/expansion-connector-of-m5stack/

  Make sure you use a non polarized capacitor like the orange one shown in the left picture. If you use a polarized capacitor instead, you might get it backwards. If you hook up an electrolytic capacitor backwards, the electrodes oxidize and it starts to conduct current. Throw away any polarized capacitor that you hook up backwards. You can also use RST and BAT since it's easier (IMO). http://forum.m5stack.com/topic/113/an-even-simpler-fix-when-upload-fails I heard the new M5's don't need the cap but I'm waiting for a new one to arrive to confirm.

  @wwh1260051266 @ia2018 There is an interesting blog about BLE and the M5Stack as well as some code for the M5Stack at the links below. I haven't had a chance to try the code but it works for the writer. Similarly, this code uses 75% of the flash memory. BLE must be greedy.

  @m5stack 在 usb host 中说： ch376 The ch376 is mainly for storage. What if I want to use usb OTG functions and use a mouse with the M5Stack or some other usb input device. Can I use this SPI device. https://www.amazon.com/HiLetgo-Development-Compatible-Interface-Arduino/dp/B01EWW9R1E/ref=sr_1_cc_1?s=aps&ie=UTF8&qid=1519186851&sr=1-1-catcorr&keywords=usb+host+shield+2.0+for+arduino

  @jpilarski Hi, i agree the M5Stack is indeed a really great device ! Regarding your query, you can review a list of command functions here: https://github.com/Kongduino/M5CheatSheet Also you can review the code from this excellent working menu system by Tom Such that uses the buttons for selection: https://github.com/tomsuch/M5Stack-SAM He also created a template program for making your own menu: https://github.com/tomsuch/M5StackSAM

  I just wanted to update that I finally got it working. I uninstalled v4 of the Silicon Labs VCP driver (using the uninstaller.sh script from the zip file below). Then installed the latest driver from this file: https://www.silabs.com/documents/public/software/Mac_OSX_VCP_Driver.zip I did not install the legacy driver. I used "Silicon Labs VCP Driver.pkg" from the main directory of the zip file. Next, I had to do a fresh install of the Arduino IDE 1.8.5, then followed the same instructions here: https://github.com/m5stack/M5Stack/blob/master/docs/arduino-ide/mac.md After I restarted the Arduino IDE, I now saw the M5Stack-Core-ESP32 listed under the Tools > Boards > ESP32 Arduino menu. No need to do anything with the Boards Manager.

  @kryten While not ideal, an alternative option may be to setup another wifi router on the network and set it up without the space in the SSID.

  Mhh I think I finally got it working. I was using WifiMulti.h and it seems there was the problem. Something with TLS handshake. I swaped to Wifi.h and now seems to work.

  Hello, I have uninstalled the previous setup, deleted all files and redeployed everything using guide at https://github.com/m5stack/M5Stack/blob/master/docs/arduino-ide/windows.md This time I can properly see the M5Stack-Core-ESP32 board on the list. Thank you for the help. Is there any way we can request an update of the http://www.m5stack.com/assets/docs/index.html to avoid confusion in the future?
