Huzzah ESP8266 not recognised on a MacBook Air

[andreagrandi]

Hi,

when I connect my ESP8266 board to my home MacBook Air it's not being "recognised" at all. I don't see any new device in /dev/*
If I connect the board on my work MacBook Pro instead it's recognised and available on /dev/tty.SLAB_USBtoUART

They are both running latest OSX (10.11.3)

I can't find any explanation for that and the only suspect I have is that MacBook Air doesn't give enough power to the board so it's not able to be mounted.

Which commands could I try on my MacBook Air to understand if the device is recognised by the system at all?

Thank you so much, cheers.

I resolved the problem! I tried installing this driver: https://www.silabs.com/products/mcu/Pag ... ivers.aspx
because that's what I found searching for the device I see when the board is connected:

Code: Select all

➜  pydojo  ioreg -p IOUSB -w0 | sed 's/[^o]*o //; s/@.*$//' | grep -v '^Root.*'
BRCM20702 Hub
Bluetooth USB Host Controller
USB Optical Mouse
CP2104 USB to UART Bridge Controller

after installing the driver I was able to connect to the board:

Code: Select all

>>>
MicroPython v1.6-150-gd973c1b on 2016-03-07; ESP module with ESP8266
Type "help()" for more information.
>>> print('Hello MicroPython!')
Hello MicroPython!

Thanks for sharing andreagrandi. Have you installed the driver using the package manager or fetched them from the silicon labs?
A note on the USB to UART capability check can be included in the official documentation too. I don't remember having to do that on my linux machine however.

Hi,

I installed the package downloading it from the link I previously posted.

Cheers
