Hello,
I'm receiving the following errors:
warning: espcomm_sync failed
error: espcomm_open failed
error: espcomm_upload_mem failed
error: espcomm_upload_mem failed

I have attempted to fix this problem through:
*Making sure I"m using the "NodeMCU" as my board in the Arduino IDE
*Trying different upload rates
*Pressing and holding the flash button while and/or right before upload

Hardware:
PC, windows 10
NodeMCU from eBay link above.

Any help? It appears others have had this problem as well, but I haven't (yet) been able to fix my issues through their threads.

Thanks!

Toozinger
