Can't see Freematics ONE v4 in the list of COM ports on Mac OS in Arduino IDE #31

Closed timurrrr closed 7 years ago

Hello,

I'm trying to follow http://freematics.com/pages/products/freematics-one/guide/ to start working with my Freematics ONE v4.

When I connect the device to my MacBook Pro using a USB cable, I can't see any new COM ports available in the Arduino IDE. I can see new COM ports when using other devices (Uno, Micro, ESP8266 boards), but not Freematics. I don't see anything related to Freematics when I run "ls /dev" in the Terminal, although I do see other COM devices there. I have Mac OS 10.13.3 Sierra, in case that matters.

I don't get anything written on my FAT SD card when I plug it into the adapter.

However, when using the Arduino IDE for Android using an OTG cable I can at least see ACC/GYR/MAG lines on the serial monitor, so seems like the device is not broken. I can't upload a Blink sketch though.

Unfortunately, I don't have any other host devices to try with the Freematics ONE. Can you please advise on how to set up the COM to use Freematics ONE from Arduino IDE on Mac OS? Thanks!

Ah, I looked at the schematics and saw that you're using the CP2102 chip to do USB2USART. I quickly found this driver download page: http://www.silabs.com/products/development-tools/software/usb-to-uart-bridge-vcp-drivers

You may want to switch to use a driverless USB chip in the next hardware revision.
