Sonoff Basic - AP not apearing on first boot with pre-built BIN

[VanadiumJade]

Hi,

I have setup 2 Sonoff basic and 2 Sonoff wall plugs and 3 Sonoff POW all with Espeasy.
I have got the hang of it... I have order 15 more Sonoff basics. I seem to have an issue with the new batch.

I have been using R120 and flash program to write FW.
I do the same steps I have done with all the other devices.
- Solder pins
- Plug in to laptop with button held down
- flasher com6,1024,120
- Plug into power source and AP apears ... configure and good to go.

last step doesn't work... AP doesnt show.

Is there something I am missing? because it worked for 7 previous devices... but this lot doesnt seem to work.
I will try a few more... but I dont want to brick 15 of them.


Thanks in advance.

I got exactly same issue with a new batch of Sonoff I just bought. No out in serial as well.

[LisaM]

What are the specs (mem/soc) of the current sonoff basic batch?
And when using the Arduino IDE to compile & upload?
Output of the upload?

[seikan]

It seems like the new Sonoff Basic are shipped with new chip.
Flashing using the Flash tool was done without error, but the AP will never get discovered.

I have to use the Andruino IDE to compile the latest firmware and flash it with DOUT mode to finally get it working.

Hi is there any fix for this yet? I have two SONOFF units and they worked fine until i flashed them with the same settings as above and now they dont seem to do anything.

If i boot them with the button pressed they still go into upload mode as if i dont press the button the upload tool errors so i know they are not dead. When they boot after the firmware update there is no led activity on the unit and it does not appear as a wifi AP.

Any help would be great.

Hello Forum

i have the same problem.

i flashing 3 Sonoff Wifi Basic with 2.0 dev11 Bin File and after the Sonoff ESP doing nothing.
what i do:
- flashing with ESPTool ESPEasy_v2.0.0-dev11_normal_1024.bin --> Flash OK, but after Restart no AP is open
- flashing with ESPTool ESPEasy_v2.0.0-dev9_normal_1024.bin --> Flash OK, but after Restart no AP is open
- flashing with ESPTool ESPEasy_v2.0.0-dev9_normal_4096.bin --> Flash OK, but after Restart no AP is open
- flashing with ESP Flash Download Tool V2.3 ESPEasy_v2.0.0-dev11_normal_1024.bin --> Flash OK, but after Restart no AP is open
- erase mem (http://www.pratikpanda.com/completely-f ... sh-memory/) and Flash ESPEasy_v2.0.0-dev9_normal_1024.bin --> all OK, but no AP
also try the test and dev files with same nothing...

i used an CH340 Serial Adapter for programming and a Laboratory power supply for the 3.3V. The ESP does not consume any power. Maybe 1-2 mA. If i pressed the button needs 35 mA.

last week i flashed 2 Sonoff Basic with the same dev11, same Adapter without any problems. They working perfectly.
but now i ordered 5 new Sonoff. 3 of them are with this problems. 2 I have not flashed yet.

the serial Output is:
----------------------------------------------------------
ets Jan 8 2013,rst cause:1, boot mode:(3,6)

tail 8

csum 0xef
csum err
ets_main.c
----------------------------------------------------------
please can anybody help me ?

sorry for my bad english.

[grovkillen]

Just a reminder, the basic is a 1MB device (as standard, it's possible to resolder it with a 4MB chip) and thus you need to use the "1024" bin file.

Regarding the problem it seems that the latest batch is using a different setup and need to be flashed differently than the official compiled bin. How this is done I have not a step by step guide but you need to compile yourself as of now. We need to document this on the wiki though.

"When they boot after the firmware update there is no led activity on the unit and it does not appear as a wifi AP." others seem to follow.

[supergrobi]

i read somewhere in the INet should used the DOUT mode for programming.

i do this with the ESP Flash Download Tool V2.3 and now one Sonoff is working !!!!

later i will check the other sonoff's

Edit: other modules now also working after flshing in DOUT mode. it's crazy the radio Button SPI Mode jumps back to QIO Mode after start programming.

[AndrewJ]

It would be good if someone would add this info to the Wiki. I'd do it myself, but I don't believe I have the access to it?

Serial output?
Flash method?
Unfortunately, i'm not telepatic. You need to tell us as much details as possible. For you it's clear, but your environment is unclear to us...

[shanekuz]

I have tried both with the Arduino IDE and ESPtool.exe im pushing the 1024.bin image using a USB - TTL board using the 3.3V pin. If i dont boot the SONOFF with the button pressed then both applications fail to upload so the unit seems to be able to still be programmed.

If i boot the unit with the button pressed i cant telnet to it to run TTL commands which was a test i found so i cant run AT commands serial to the unit so it may be dead im not sure.

I have to use the Andruino IDE to compile the latest firmware and flash it with DOUT mode to finally get it working.

Which command did you use in Andruino IDE? And which FTDI chip did you use?

Because I have the same problem .

Same problem here with brand new Sonoff 4CH ! I can flash it without problem but Wifi sugnal never shows up I tried also in DIO mode for flash but not much more success !

USB-TTL adapter: CP2102

If you have any ideas what to test, I'm ready for it

Thanks

Hello vincen,

did you consider that the 4ch Sonoff does not use a ESP-8266? It is an ESP8285, a slightly different processor.

ESPEasy runs on the 4CH sonoff, but you have to compile a version for the other processor.

Yes, but you cannot use the pre-compiled ESP8266 version...
You need to compile it yourself with Arduino IDE using the ESP8285 board.

Completely lost here as I thought it was included by default in 2.0 version so I don't see the point to recompile it to get support for it ! In all matters if it needs to be recompiled I have to give up (never succeeded to follow all steps to setup environnment for that Or perhaps someone has the file avalaible for test ?

Use the bin file ending with "8285". This is something that will be changed in the future since it is a bit confusing having the name that way. See this request: https://github.com/letscontrolit/ESPEasy/issues/444

Sorry LisaM but I confirm you that standard bin file of ESP2 works well as is on Sonoff 4CH I have Problem was with parameters of flash and here is correct command with bin file downloaded from github Once flashed, I just removed few seconds power supply from FTDI adapter to the Sonoff then plugged it back and after few seconds my favorite ESP wifi signal popped up Unhappy I can't go further When I succeed to access the captive web portal and setup my Wifi, I get the notification to wait 20s but at the end it comes back as ESP_Easy instead of connecting to Wifi. I have already few ESP modules connected to Wifi so this one should not be a problem !
Some ideas about something to investigate for that ?

Update: Redid the flash with version 2 and with 8285 file and it works like a charm now same flash command line with the 8285 file and it's all setup ( I have 4 of these and they are now operationnal with my Home Assistant system through MQTT ;) Might be nice to update Wiki with instructions no ??

Even the older R1xx versions can be used with Sonoff 4ch, i'm running a R148 on it.

But the standard binaries are compiled for the ESP-8266, not for ESP-8285!
As the two CPUS handle the memory slightly different you must compile a binary suitable for the CPU.
If the source is compiled correctly it runs on both.

Thanks, Alphons!! After a lot errors your post is the solution

[awclem]

I had the same issue. I solved it but I am not sure if what I have done to solve it is going to cause me any additional issues if the memory size has not changed.

I solved the issue by flashing the 8285 version of the firmware instead of the 1024 size. I now have 4 working devices using this. I was just assuming that the company has upgraded the memory on the new units.

If this is something that is going to cause me issues I would sure like to know it ASAP.

Nope it's the correct firmware in fact 8285 is fos chip reference not memory size so you are all ok there

[psy0rz]

I think we already have a precompiled ESP8285 version, that should work right?

I have a few brand new Sonoff Basic devices - the ones with the new chip that required DOUT rather than DIO, apparently, though I am having trouble flashing ESPEasy binary images on these devices with it set to DOUT or DIO.

I have successfully flashed these devices with a blink sketch using the Arduino IDE, so I know my USB-> serial is working ok. I'm pretty sure the Arduino IDE is using DIO though, as '-bm' is not specified on the command line (see example further down this post).

Here is one of my attempts at flashing an ESPEasy binary image, with console out (I'm on a Mac):

$ esptool -vv -bz 1M -bm dout -cd ck -cb 115200 -cp /dev/cu.wchusbserial1410 -ca 0x00000 -cf ESPEasy_v2.0.0-dev12_normal_1024.bin

Immediately after uploading this the Sonoff blinks away happily.

As a side note, I HAVE successfully flashed an AdaFruit Huzzah with the R120 binary image specifying -bm DIO, so the image is also fine.... It's just these Sonoffs that I'm struggling with.

Any advice would be gratefully received.

Hello all

I have a Sonoff S20 which I've read is almost identical to the Sonoff basic. I'm able to upload espeasy but as with others.. there's no AP. There's a twist to this story though... As I did manage to get it up before..
This is what happend:
Tested the original unit with EWelink - all was ok
Soldered header and used Adruino IDE to flash espEasy R120 - all went well
ESP_0 AP came up and I started to configure the unit....whilst going through the config I thought I could load up a config from another Sonoff Basic I have, then update the parameters like IP address, name etc.. but the config wasn't showing up So i rebooted the unit..... It went downhill from there..i Iost connectivity . I turned off my WiFi ap in the hope of seeing esp_0 on the unit but that didn't happen either. Ive tried to flash espEasy on again.. which seems to go on successfully... But no Esp_0 ap. I get no output over serial nor can I send any commands (using putty)

Flashing Tasimota works fine..

I have a feeling that config data is persistent and that is what's causing the problem. I may need to do some work of memory wipe, and start again.

I anyone out there able to help?

[Shardan]

- Disconnect the S20
- shorten Tx--Rx with a jumper cable
- power on and wait some seconds
- power off, remove jumper.

This erases the chip memory.

Regards
Shardan

[sups]

Thanks Shardan
I'll give this a go when I get home. Incidentally...Do you have any idea what kind of response I should get from the on board LEDs when doing this?

[Shardan]

Honestly i don't know.
My S20's are still on the way from china
Hopefully the customs won't reject them.

[sups]

Just an update.
Shorting tx/Rx didn't work for me.. I had to use the espTool from
Espressif. There is an option to clear the chip which worked. I then used Arduino IDE to load EspEasy on again.
Phew!

Oh and my unit also came from China... Took about 3weeks to deliver to my home in the UK.

[mrwee]

Just flashed a new Sonoff S20 (V1.3) with the Arduino IDE and ESPEasy v2.0.0-dev12 and flashmout 'DOUT'. Flashed and ran in first 'go'.

I do still get "Error while reading/writing config.dat in 926" with this new device

[sups]

Is there much of a difference between R120 and 147?.....

[mrwee]

Is there much of a difference between R120 and 147?.....

I did not try R147 on this new S20, but v2.0.0-dev11 did not fail on my previous test-S20.

[jackwan1]

@alphons

I received the NEW sonoff basic from itead today.

I followed your instruction to flash the Espeasy normal v2.0 with the flashing tools from Espressif per your instruction.

I was successful and reboot the sonoff and on the Wifi ssid, I see ESP_Easy_0, but I cannot logon because it requires an 8 digit password.

Please advise the password.

[jackwan1]

Thanks all,

I was able to log onto the sonoff and change ip address of my desire and proceed to configure this for domoticz.

When I reach the "HARDWARE" section, as usual, since I had many sonoff, I change the wifi status led to GPIO 13(D7), as soon as I did that, the led on sonoff goes on and I was disconnected from the router and no longer able to log on. What gives?
