Hi,

I have spent yesterday and today trying to establish a usb connection to this unit which I first unbagged this week. I am running Arduino 1.8.19 on both a MacOS 10.13.6 and MacOS 10.15.7. I have installed the Silicon Labs CP210x USB to UART software version 6.0.2 on both, and used 2 different cables. Have tried the 3 Port options presented: dev.Bluetooth-Incoming-Port, dev.SLAB\_USB to UART, dev.USBSerial-1420 as well as a lower baud rate. Using the Get Board Info option within the Tools menu, I get “Native Serial Port can’t obtain information”

What should I try next?

Thanks

I’d say try ensuring the power supply isn’t over 5v [https://learn.sparkfun.com/tutorials/es … troduction](https://learn.sparkfun.com/tutorials/esp32-thing-plus-hookup-guide?_ga=2.87529242.349259513.1641837921-1853259630.1615791300#introduction) and using the reset button to see if that’s hanging it up

If you can’t get it working after that, head to [Return Policy - SparkFun Electronics](http://sparkfun.com/returns) and fill out the form (reference this forum post) and we can get ya squared away

Hi,

I was able to communicate with Thing Plus v1.0 today. It seems that some part of the Arduino software is expecting MacOS 10.15 . My main machine is running 10.13.6. Below is the most verbose compiling log I have ever seen, towards the end it says: " (which was built for Mac OS X 10.15)" , so I guess that is the minimum OS to fully run the software. It runs on another computer running Mac OS 10.15
