- Sun Aug 20, 2017 1:04 pm #69331 I just got a new badge.
Disconnect the esp8266-01.
I give 5 volt voltage to the plate.
The D2 led D2 flashes constantly.
According to the schematic is the output to the relay.
I should not flash.
The supply voltage is correct.
Any ideas?

Hi Janage
when you upload your code which board do you use in the IDE? I used "Generic ESP8266" and cannot get it work, either at 115200 or 9600 baud.

The error messages are:

warning: espcomm_send_command: wrong direction/command: 0x00 0x08, expected 0x01 0x08
warning: espcomm_send_command: wrong direction/command: 0x00 0x08, expected 0x01 0x08

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

I installed the esp-01 on the relay and use ftdi to supply 5v on the relay board and connected rx, tx and gnd on the relay board and then tried to upload the code.

I'm having the same issue. Can someone share the configuration/set-up they are using to load sketches via the Arduino IDE please
