Hi All,

I am trying to complete a project similar to the one shown below but I am using a 3 prong DHT instead of the 4 pronged one in the picture. Other than that that is the only deviation that I have made to the original design. I have received 4 errors/ warning that is preventing me from completing this project. I have researched and have can up with no reasonable explanation as to why it is not allowing me to upload. Can I please get some assistance. Thanks!

Errors
warning: espcomm_sync failed
error: espcomm_open failed
error: espcomm_upload_mem failed
error: espcomm_upload_mem failed

 

I know it can be difficult for new AAC members to understand, but the more you reveal the details, the greater the likelihood of getting help. Otherwise, there is a lot of guessing.

So, my 2 guesses are:

1. You are using the Arduino IDE and you do not have the board/port correctly identified

2. You are using a version of Windows that is particularly annoyed with the CP102 driver (or it hasn't been installed) and it is probably some CH340 variant.

 

If your using a nodemcu use the 0.9 for board and make sure you set for the right comport
under ports.
I have a 1.0 and it will not program as a 1.0

I get the same errors you posted.

But if it doesn't show up under ports you have to tell us what OS your using.
newer ubuntu doesn't need know drivers and I have not had to install any on windows 10 but some say they have to .
