Problems after Switching from ESPlorer to Arduino IDE

By siriusPhil
- Mon Feb 08, 2016 1:56 pm #40719 My setup:
Seeed nodeMCU_v2
MacOS 10.9.5
Arduino IDE 1.6.7
Board: nodeMCU 1.0…
CPU Frequency: 80 MHz
Flashsize: 4M…
UploadSpeed: 115200
Port: /dev/cu.SLAB_USBtoUART
File: nodedMCUBlink (from Adafruit)

Error:
warning: espcomm_send_command: didn't receive command response
warning: espcomm_send_command(FLASH_DOWNLOAD_DATA) failed

This same nodeMCU was working fine with ESPlorer (same port, same cable) before I tried to use
Arduino IDE.
I hold the Flash button down and then click Reset buttton. No LEDs are on. I see the blue LED on the ESP board flash while uploading. Also tried holding the
Flash button while plugging the USB cable. Sometimes the IDE just hangs during the upload.

These are not that great for loading FirmWare. Ihad only 2 of 10 that would load FW.

Crystal controlled ones are better, and just as cheap....


It is a nodeMCU so it has a CP2102 on board. As I said everything worked perfectly when using ESPlorer and Lua. I have downgraded the Arduino IDE to 1.6.5 per the git page suggestion but same problem. I am about ready to go back to ESPlorer (ugh!)
btw, I have built many projects with FTDI chips and had no problems loading firmware or otherwise.

New:
I had a friend come by and help out. It turns out that even though my setup worked fine with ESPlorer, I had to bypass the USB hub and plug the nodeMCU directly into the Mac. Now Arduino IDE is working fine but it was a struggle before this.
