Hallo allerseits,
ich bin neuer im Forum. Ich habe etwas über mein Problem mit den gerade gekauften SP112 recherchiert und leider gar nichts gefunden. Es könnte auch sein, dass ich etwas nicht merke/verstehe/begreife/falsch tu usw. Deswegen möchte ich einen Rat von der erfahrenen Herrschaft lesen oder eine Diskussion anstoßen.
Die neuen SP112 vom Jahr 2021 mit zwei USB-ports sehen genau so, wie frühere Modele. Allerdings lassen sich mit Tasmota auf keiner Weise flashen. Über die Meldungen, dass die Methode tuya-convert über WLAN bei SP112 nicht mehr funktioniert, habe ich bereits gelesen. Aber die serielle Methode funktioniert leider bei mir auch nicht. Beschreibung: Alles angeschlossen, angelötet nach Referenz . Das erste, was auffällt, dass die Leuchte nach dem Auflösen der IO0-Brücke nicht lange Rot leuchtet, sondern nur 4 Sekunden. tasmotizer.py gestartet (probiert auf Macos/Linux), den richtigen SerialPort gewählt, release 9.5.0 tasmota.bin beim Image gesetzt. "Tasmotize!" geklickt und nach einer Weile "Failed to connect to ESP8266: Timed out waiting for packet header" angezeigt bekommen. Wenn man die Platine anschaut, fällt auf, dass sie etwas anders als die auf den Bildern von alten Youtube-Videos und der Anleitung von tasmota.info ist. Ich habe die Bilder hochgeladen. Hat jemand Erfahrungen mit dieser Version von SP112?
Wenn ich Recht habe, ist diese Version im Moment nicht flashbar mit den aktuellen Versionen der Flash-Programme. Das sollen Bastler wissen, finde ich.signal-2021-06-26-120820_001.jpegsignal-2021-06-26-120820_002.jpegsignal-2021-06-26-120820_003.jpegsignal-2021-06-26-120820_004.jpeg

Hi Sergey,

"Failed to connect to ESP8266":  it's maybe not an ESP8266 or it's not in flashing mode..
do you have some serial debug outputs ?
did you try with esptool to "read" the chip ? which chip ID is it giving you ?

Hi Erik,
thank you for your answer.
unfortunately I don't have this things anymore. But I think this is the case, it is out from the flashing mode before I start to flash. May be it wait for a special handshake over serial. The led has been being red only for 4 seconds. Normally it is always red after the disconnection of the IO0 bridge.

It may be worth connecting via a terminal programme when you power up as it will often give a clue to the firmware/device.

Hi 
I have the same Problem with same new AI Board, and still have the board:)
I just tried connecting over putty serial but no success. I am not sure if I am doing it right... 
No idea if led behaviour gives a clue : 
When I power it on (USB only) starts with blue light and then blinks blue
When I power it (USB only) with IO0-GND shorted, then it starts with red light and red stays on during the time I bridge them, but blue starts as well, and after releasing bridge only blue blinks...
Still nothing on putty...
 Any other suggestion I can try on?
Regards
Zaf

This is what I get from an ESP32 (I’m using Tera Term on Windows). Up until 0.160 is the hardware after that is Tasmota.

If you are seeing nothing at all try to swap Rx and Tx

Hi Phil,

thanks for recommending terra term, it looks more comfortable than putty.. 
during pressing harder if there is a miscontact,  I just broke all solder pads :/, looks like soldering headers directly on the flat pads without holes was just not a good idea.
OK I haven't been soldering for long :) 
I opened up the second plug and found out the right contacts, 
so if anyone else ends up destroying the pads, can also solder directly to processor contacts...
looking at processor with 6 contacts on top and 7 on bottom and counting from left ´:
1 -RX
6-GND
7-TX
9-IO0
13-3.3V
Finally got the soldering OK, this time soldered cables instead of header but still got one pad out... 

Till now:
I tried swapping, with/without IO0-GND bridging for few seconds, reset button w/wo IO0/GND...
I tried putty, terra term, microcom and minicom via mobaxterm and tried also on linux ... 
but still no success... I still see nothing... :(

Just to make sure, I tested the same ftdi again with an other board, it works on terra term or minicom/microcom without any problems...

Regards,
Zaf

I'm having similar issues. My PCB looks just like the one in the pictures.
I am unable to get it to flash. I am trying to flash EspHome onto it, but I believe the underlying tool (esptool) is the same. 

This is my first attempt at refreshing an ESP in a device, so I may be doing something else wrong, but I don't think so. 

I'm seeing the same thing. the red LED turns off as soon as I release the IO0 pin and flashing fails. 
I hooked up a scope to TX from the PCB and there's no traffic. The pin goes high for about a second on power up, but then goes low and stays low, no matter what. 

Here are some scope traces:
TX - Yellow
RX - Green
IO0 - Blue

Not holding IO0:
notHolding.png

holding IO) for 2s:

holding_2s.png

holding IO0 for 5s:

holding_5s.png

You can see that IO0 Stays at around 2V for about 4.5s then briefly dips to GND and then goes and stays at 3.3V
This is the same time that the blue LED turns on. 

Here one more with nothing connected to RX, TX and IO0:

Ok, I cracked open the RF shield can and low and behold, this is NOT an ESP8622
IT's a W701:
W701.png


"WBR1-IPEX is a low-power embedded Wi-Fi and Bluetooth module that Tuya has developed. It consists of a highly integrated wireless RF chip (W701-VA2-CG), with an embedded Wi-Fi network protocol stack and varied library functions."

So there's currently no way to reflash these I think.
Some more discussion going on here:
