In reply to Jeff in Texas. Hi Jeff, thanks for the pointers. I will take a look at both Arduino-flavor C++ and Tasmota.

In reply to David. I have repurposed Sonoff Basics both with Arduino-flavor C++ and Tasmota. I assume that Tasmota is written in C++ as well. If you want to use Micropython, you'll need to flash it with Micropython first and at least for starters, do your programming via the serial port. Doesn't really sound like a project I'd want to do. Probably too resource-constrained.

Hi I’m also trying to get this working. I have a Sonoff BASIC, the motherboard is v1.3, with an ESP8285.

I connected the board via FTDI as described. On this version of the motherboard, in order to boot in flashing mode, it’s necessary to ground the “key” (by connecting 2 of the 4 solder points under the fat mains wire traversing the board).

I seem to have flashed the chip sucessfully, but cannot get any response from the web server.

Is this script written in C? I was expecting to write some micropython with this board.

Thanks for the great tutorial, and to anyone who can help with the updated boards.

Hi .super thanks.
I’m looking for an e-stop feature for safety. HTML Button which quickly ends ,break the action on wifi, server,client. Is there such a function in the libraries ????

*** Sorry, that was to be ESP8285. ***

I always use:
board = sonoff_basic
instead of ESP8265. Seems to work well. …greg

In reply to zhekaus. Two guesses: First, swap Rx and Tx on one end, and second, dry solder in header; that is bad soldering of one or more pins. Let us know. ...greg

Hi! I successfully flashed Sonoff 220V Esp8266 relay module. Thank you.
But I need to flash another version of Sonoff relay – 5V, based on Esp8285.
And I’ve got problem here.
I am trying the same process:
– Solder pin 3V3, GND, RX, TX
– Connect pins, to the same FTDI adapter
– Choose the right board – in this case, Generic Esp8285
– Initialize flash mode with a button
– Upload Blink sketch

And nothing – «Connecting…….._____….._____…..»
I tried different options of Uploader. In wane.
Can you help or give an advice?

In reply to Maurizio Bazzoni. Have you found a way to program Esp8285 version?
