  • What do I do with the DTR and VCC lines when using the sparkfun FTDI cable? I am continuously getting the espcomm_sync failed errors/warnings.

  • Thanks for your response. I tried what you recommended though I can't stop getting the espcomm_sync failed and espcomm_open failed messages. I've tried the turning it off then back on right before upload method.. Any other suggestions? Also, shouldn't I connect the 3.3V to the shifter? Thanks!

  • Is there a way to program this with Sparkfun's RS232 shifter https://www.sparkfun.com/products/449 ? There isn't a DTR pin and I don't have an FTDI basic handy. Thanks.
