Let's Control It

Hi,

I'm trying to flash Sonoff 4ch Pro with ESPeasy firmware but I have an issue.
I'm using a surface pro 4 running on windows 10 and I have already done a firmware flash on sonoff basci and sonoff S20...that was OK and working.

But now, on sonoff 4ch pro I have tried the same operation and failed.
Here is what I did:

- firmware : ESP_Easy_v2.0-20180227_normal_ESP8285_1024.bin
- flashing tool : FlashESP8266.exe
- connections :
GND (sonoff) on GND (FDTI)
RX (sonoff) on RX (FDTI)
TX (sonoff) on TX (FDTI)
VCC 3.3v (sonoff) on VCC 3.3v (FDTI)

I get error as described in attached files.

For info, I have also tried with external power supply 12v / 2250ma..same issue.

I think/suppose the sonoff is not correctly in programming mode.

Do you have an idea?

Thanks
Laurent

Swap RX/TX since the transmitter should be sending to the receiver.

Why try such an old version (3 weeks old)?
In the newer builds are versions included with "_DOUT" in the filename.
For newer SONOFF devices, you need those DOUT versions.

Ok works fine thanks

but is it normal that the first 3 lights are on ?
The blue light (for wifi) is off...but I can see ESP_Easy_0 wifi network.

See picture attached.

sorry, I made a mistka with my copy/paste, firmware I use is : ESPEasy_v2.0-20180316

on sonoff 4ch pro, do you know where is the button to use to include it on jeedom (inclusion mode) ?

I have same issues. I try flash sonoff4ch pro with firmware ESP_Easy_v2.0-20180313_normal_ESP8285_1024.
Flashing doing well. But I have 3 lights on 4ch pro, and on my usb to ttl blink Rx led lights.
ESP0 does not appear. I also try old firmware.

On all my 4CH Pros the red LEDs light up on reboot -- some all 3, some just 2. No idea why.

I just do this:

on System#Boot do
GPIO,12,0
GPIO,15,0
GPIO,5,0
GPIO,4,0
endon

in my rules to reset them.

You have to go into hardware and set GPIO13 for the LED. If you're not using the I2C interface, set those to none, otherwise you'll get random green flashes on one of the LEDs.

That is ok, but I cant login with browser. I cant find esp 0 wifi.
So I think that problems about flashing.

what do you see on your serial output when you boot?

Hi,

I have added this rule into RULES tab.
Works fine but everytime I switch off sonoff power supply and then when I turn it on again, garage door open or close (depending of his initial position).

this is not very safe because If I'm out of my home, if there is a main electricity failure, and then when electricty's back, doors will be opened.

do you know why I get this behavior?

Are you using MQTT? Do you have the command retained on the broker side?

Have the same issue. 3 lights on 4ch pro R2 and can't flash (after success flashing). viewtopic.php?f=5&t=6054&p=33065#p33065

Does anybody solved this?
