Freematics One+ Upload error.

Hi,

I am trying to upload SIM5360Test.ino in my newly purchased Freematics One+ using Platform IDE, But I am getting the following error.

esptool.py v2.3.1

Connect the unit to OBD port, or, connect USB to a USB hub with external power supply. Your computer may not be able to supply enough current surge.

I am having the same issue.

I have tried different USB ports and cables, and tried plugging it directly into a vehicle with a known working OBD-2 port.

What other options are there to get this device to work?

Connect the unit to OBD port

Alternatively, use a USB hub with external power input.

For others that may run into this. I was getting this same error. I tried powering it with OBDII port, external power supply etc. But still got the same error. I did find a solution though. It was happening on a Windows 7 computer. I actually got about 2 out of 30 uploads to succeed but it was very inconsistent. I tried on another Windows 10 computer and it flashes every time. Not sure what the root cause of this is. Maybe there is an issue in the Windows 7 CP210x drivers? Maybe a timing issue associated with those drivers?

It would be nice to find a work around to get it to work with that computer as its my main computer... but for now I have a workaround.

On Windows 7, download and install latest CP2102 driver manually instead of using system's default one.

Hello, just wanted to post my fix to this problem, in case anyone else was still having it.
I did not have Arduino IDE installed on my computer when I was having this issue, as I didn't realize that it was necessary to upload files to the One+. After installing Arduino IDE, I was successfully able to upload code into the One+.

Hope this helps,
