Hey there!
I’m still pretty new to the whole Blynk/Arduino/SparkFun environment, actually studying chemistry, but I wanted to make my IKEA Väter Farm smarter by adding a “SparkFun Enviromental Combo Sensor” and a “Pololu Relay” to control the whole setup via Blynk. I don’t have problems with the code or wiring, but with uploading the code to the board. When I try to do that, and I configured the Arduino IDE like the said on SparkFun, I get the following error message:
Using 921600 Baud
warning: espcomm_sync failed
error: espcomm_open failed
error: espcomm_upload_mem failed
error: espcomm_open failed
Using 9600 Baud:
Uploading 253088 bytes from to flash at 0x00000000
warning: espcomm_send_command: didn’t receive command response
warning: espcomm_send_command(FLASH_DOWNLOAD_DATA) failed
warning: espcomm_send_command: didn’t receive command response

Would be great if someone knew a solution for that problem
