Flashing SONOFF with Homie-Sketch does not work

[gtom]

Trying to use a itead sonoff-switch. There are some issues down below, but my problem seems to be a little bit different. Sometimes (very seldom) I am able to flash one of sonoff-homie-examples (sonoff), after flashing the normal configure-mode starts. But in most cases after flashing the example the led just remains off (IDE reports flashing OK). It looks like nothing is happen.

I read in some issues down below that esptool erase should help before flashing - unfortunatly not in my case. I also changed my Arduino-IDE-config from 1M-64K SPIFFS to 512K-64K SPIFFS. Didn't help either. I tried platformio to flash same example with same result. Always it reports success in flashing, but config-mode doesn' t start. I thought it could be a problem in flashing, so I tried another example (just a blink, without homie). In this case every flash is OK, the device reboots and LED starts blinking. I don' t think that this is a homie-bug, but it seems to be homie-related. Maybe someone has experience in flashing sonoff with homie-sketches and can point me in right direction? Thanks gTom

Hi - Make sure you are using "Generic ESP8266" setting (at least in Arduino IDE)

I have quite a few SONOFF's running Homie.

I second that, however I don't use that ATM, see: https://github.com/amayii0/Homie-Sonoff https://www.instructables.com/id/Use-Homie-Firmware-to-Drive-Sonoff-Switch-Module-E/

Ahh... I haven't take the time to dive into PlatformIO...Guess I should

No, does not work: I tried the sketch from amayii0 above via platformi0. This is my platform.ini: `

[env:esp01] ;[env:esp01_1m] platform = espressif8266 board = esp01 ;board = esp01_1m framework = arduino lib_deps = git+https://github.com/marvinroger/homie-esp8266.git#develop

` I tried both esp01 and esp01_1m with erasing flash between my trials.

Maybe this info helps: I did catch messages during boot process with Arduino-IDE. This is what the device says (repeating):

`

ets Jan 8 2013,rst cause:4, boot mode:(3,6)

wdt reset load 0x4010f000, len 1384, room 16 tail 8 chksum 0x2d csum 0x2d v3ffe8580 ~ld

`

What sort of Sonoff switch? The touch switch uses the esp8285, which if memory serves will result in a the behaviour you describe if you compile and flash esp8266 code :-) I have working Sonoff touch switch code at https://github.com/kylegordon/homie-sonoff-touch if it helps.

No, it is this one: https://www.itead.cc/sonoff-wifi-wireless-switch.html And because some simple sketches work, it doesn' t seem to be related with cpu. Maybe it has something to do with used memory: including the homie-libs eats more memory. In the next day I will try to extend a simple blink stepwise to a more complex sketch and see what happens.

Have you tried https://github.com/enc-X/sonoff-homie ?

It also uses Homie, v1 admittedly, but has been working fine for me on those devices for a while now.

I'm actually in the process of trying to update that project to Homie 2

I own three of these and they work like a charm with my firmware at https://github.com/luebbe/homie-sonoff (Homie 2.0)

All the Sonoff that i have played with (TH10/16 ver2.1, Touch US ver1.0, and TH_v1.1) are ESP8266. I brought all mine in the last few months.

I use the following settings in Ardiuno are: //use the following settings when deploying to SONOFF Device // Board: Generic ESP8266 Module // Flash Mode: DOUT // Flash Freq: 40Mhz // CPU Freq: 80Mhz // Flash Size: 1M (64K SPIFFS) // Debug Port: disabled // Debug Level: None // reset Method: ck // upload speed: 115200

I have tested with Homie-esp8266 2.0.0-beta.2 and 2.0.0-beta.3

Hope this helps as i am yet to try PlatformIO.

Hi - I too have Sonoff's and have experienced some very odd behavior. One trick I learned by accident is when flashing the Sonoff's let them reboot on their own after flashing...I suspect the SPIFFS task is either hanging and/or takes quite a bit longer than "other" ESP8266s.

Also, make certain you have a solid ground between the Sonoff and the FTDI and/or simply try a known good/reliable/not cloned FTDI board.... For some reason the Sonoff's seem to hate my cheap/clone FTDIs but I never seem to have any trouble with my [expensive] SparkFun FTDI.

Lastly, try using the NodeMCU 0.9 version target... Especially on very old Sonoff's.

Good Luck - You can ping me directly if you get totally stuck.

In file platformio.ini setting board = esp8285
