Hello guys! I'm new here and new at ESP8266 but I inmediately dicovered a huge bump in the road.
This weekend I spend about 11 hours of trying and searching. First of all I was trying to make Tasmota working on my sonoff module but i got stuck in the begin phase. The arduino software with ESP8266 installed does compile the software. But it stops at uploading. It says "espcomm_sync failed" and 3 more lines but this is the one I remembered. I tried PlatformIO as described in the github wiki page and the same error pops up. So it has to be something with communication.
So I tried 3 ways of communicating, listed below:
- Arduino Duemilanove (removed the 328P and used the serial lines and 3v3 for powering the sonoff)
- Open-wire FTDI (genuine) 232 usb
- Profilic PL2303 (doesn't do a thing, chinese crap I guess)
I used a computer PSU to power (3.3V) the sonoff module.
All the options ended in "espcomm_sync failed". I did exactly what was told in the wiki page. Also the external links for configuring Arduino software and platformIO, otherwise I wouldn't even get at "espcomm_sync failed". Is there someone here that had experienced the same problem or knows a solution for this? I'm very close to throw everything away and revert back to 433 stuff. But I can't because I want this to work. If I start something, I want to end it with success! That's how I always end.
The purpose of this all is to eventually control the sonoff module(s) with domoticz. So I can combine 433 switches with MQTT all with one software environment.
I hope that there is solution for my problem.
thanks in advance,
