Question

I bought a 3-gang switch from Aliexpress. The switch contains a module with BL602 chip. As shown in the first photo, the module is SDV-002_V1.2. I could not find any information on this module. The closest one I found was BL-62B module with the same number of pins and partially pin compatible...

So I can confirm that soldering a wire to R2 and connecting it to VCC during power on is enough to put the module in BOOT mode. TX and RX pins are as described. I put VCC and GND on the pads that are on the main board. Now I have to figure out how to configure the module so that it works as it should.

Here is a pic of the setup I made. Don’t judge the bad soldering as I do not have the necessary equipment

p.kaczmarek2 · Answer

I don't know this particular module but we know BL602 pinout:

You can easily map the pins that way, especially if you have physical access to the board and the multimeter with a continuity test mode.

I've started the job for you, can you finish the mapping? You need to probe remaining pins with multimeter to check where they are going;

Btw I noticed one more thing.
it looks like TYWE3S form.
The VDD/GND locations are matching, and it seems CEN/RST are connected.
Maybe TXD0 and RXD0 are in the same place as well?
See:

I am creating multiplatform open source firmware (Tasmota replacement), right now supporting BK7231T, BK7231N, XR809, BL602, W800, W600, LN882H and soon supporting RTL and W701:

I will remove the module and take a photo of the bottom surface of the module.

Added after 19 [minutes]:

Here are the photos of the module and the PCB without the module.

There are some pins that I am not familiar with: B, G, W pins and C, R pins...

These pins are used to drive relays and touch switches..

BTW, the pads on the PCB for TX, RX and EN pins are not connected to anything (No PCB traces on the back side).

p.kaczmarek2 · Answer

Why do you think that RX is not connected? It looks like connected:

patentjyp · Answer

In the module, RX is connected, but if you look at the PCB, it's just a pad without any connection.

p.kaczmarek2 · Answer

It doesn't matter much. For BL602, for flashing, you need RX, TX and boot, please see: Btw, where are those pads connected?

patentjyp · Answer

They are connected to GPIOs which are connected to the touch chip. See the photo below.

p.kaczmarek2 · Answer

It's strange, I'd rather expect that this pin header slot is for programming. So, do you know where boot signal is?

gyenchev · Answer

I have the same modules(1 Gang) and just today I thought to find a custom firmware for them, so I stumbled upon this forum.

I believe that following your discussion we already know where TX, RX, VCC and GND are located. I see that on one of the pictures patentjyp provided of the desoldered module there is a BT pad which I believe is the BOOT signal. It would be great if patentjyp can check with a multimeter if this BT pad is also connected somewhere on the other side of the board(or if you can point me to which is the BOOT signal from the datasheet you have provided above), that way we will not need to desolder the whole module in order to be able to flash OpenBK7231T.

Looking forward to more information on the topic. If I can be of any help please let me know.

EDIT to add: So if I found correctly in https://www.elektroda.com/rtvforum/topic3927070.html the signal for BOOT is called PAD_GPIO_8 and if I follow correctly it is pulled down to ground by R2. So it might be possible to solder a wire to R2 and apply 3.3V to start the boot process. Am I following correctly ?

patentjyp · Answer

BT_EN pad is not connected to anything. There are no copper traces on neither side of the PCB.

Here, BT_EN is connected to pin 14 (CHIP_EN) of BL602 (tested with multimeter). Therefore, this BT_EN pin is indeed BOOT.

I will try flashing later today.

Added after 2 [hours] 4 [minutes]:

Can anyone point me to a link where I can download BL602 flashing tools for Windows?

p.kaczmarek2 · Answer

But I can see two pads here: one EN, second BT. Are you saying they are connected together? I also think that correct BT pin is GPIO8. EN is something else. Here is SDK with BlDevCube.exe (older version):

p.kaczmarek2 · Answer

That's the great progress, so most important part is done.

But I think we still need to check the meaning of the following pins:

I started doing sketch in paint few posts above but we need complete pin mapping for this module.

gyenchev · Answer

This is what I traced so far (I don't have my multimeter with me):
EN, BC and EN1 seem to not be connected to anything.
IO1 is connected to the WIFI LED on the other side of the board.
B, G, W are connected to PA6, PA5, PA3 respectively, which in turn are connected to the HELIOS IC( Not sure what it does) which in turn is connected to the buttons on the other side of the board through R23, R22, R17 so I believe that B,G,W are either input from the buttons, or output to the button LEDs.

On the right side of the module(as shown in picture) TX and RX are just pads and not connected to anything (Soldering a wire is possible)
C, R and IO1, are pulled to ground, but control Q5, Q4, Q3 which in turn control the relays.

IO2 and IO3 seem to not be connected anywhere.

If I followed the traces correctly the pins should map as follows:

EN --> ??
BC --> ??
EN1 --> ??
IO0 --> GPIO_12(WIFI LED)
B --> GPIO_20(Button not sure if left or right)
G --> GPIO_14(Middle button) Found by trial and error
W --> GPIO_2(Button not sure if left or right)
C --> GPIO_21(Relay)
R --> GPIO_3 (Relay for 1 gang)
IO1 --> GPIO_1(Relay)
IO2 --> GPIO_0
IO3 --> GPIO_22

It's getting late so I am not sure what else we need to figure out. Some of the pins we might need to find by trial and error, because I do not have the module desoldered and I am looking through the pictures uploaded in this thread.

Someone with 3 gang switch should flash and test which GPIO is for left/right button and which GPIO is for which relay.

P.S.: I have one 2-gang switch the same model. I think it uses the other two buttons and leaves the middle empty. I will see if I have time these days to flash it also and then I will be able to
map all of the signals. Maybe even write a post on flashing/etc.

gyenchev · Answer

Ok... So I managed to flash my 2 gang wall switch and here are the pin configurations I came up with:

1-Gang:
PIN_3 -> Rel
PIN_12 -> WifiLED
PIN_14 -> Btn

2-Gang
PIN_1 -> Rel (CH1)
PIN_2 -> Btn (CH1)
PIN_12 -> WifiLED
PIN_20 -> Btn(CH0)
PIN_21 -> Rel(CH0)

3-Gang
PIN_1 -> Rel (CH2)
PIN_2 -> Btn (CH2)
PIN_3 -> Rel (CH1)
PIN_12 -> WifiLED
PIN_14 -> Btn (CH1)
PIN_20 -> Btn(CH0)
PIN_21 -> Rel(CH0)

If you mess up the channels different buttons control different relays e.g. you press the left button but the relay for the right clicks and the right LED changes state.

Currently I want to find a way to invert the button LED so that the buttons are illuminated blue when the relay is on and red when the relay is off, but I believe that the schematic is designed that way and there is nothing that we can do using software. I found that if I set Wifi_LED_n to PIN_12 it inverts the LED state, but doing so for the relays just inverts their initial state.

P.S: p.kaczmarek2 is there anything else that we need to reverse engineer for these wall switches?

p.kaczmarek2 · Answer

Well done! One could also try doing a binary backup with BLDevCube.exe. It is possible when you enter advanced mode of the flasher.

gyenchev · Answer

I do not have a Windows machine at the moment. I used https://github.com/spacemeowx2/blflash on MacOS to write the firmware to the devices. Also, I have overwritten all of the devices that I have with OpenBK, so no original dump can be made. I believe these are Sonoff knockoffs that have some kind of modified software written to them, as if you hold the button for 5 seconds on the original firmware while in pairing mode it goes into DIY mode and creates an AP with the name ITEAD_......

ETA: I managed to find some leftover info in the eWeLink app from when I paired the 1-Gang switch to the app.

It seems that it is using the firmware of some kind of relay found on Amazon… https://www.amazon.com/QIACHIP-Ewelink-Wireless-Self-Locking-Latching/dp/B0BCVDS3VM?th=1

p.kaczmarek2 · Answer

@gyenchev , can you provide those configs by copying JSON template from "Launch Web Application"?
It takes some time to type them manually from screenshots.

So the device was bought here (link in the first post)? Price is very low.

Added after 24 [minutes]: Still looking for a way to dim the brightness of the button LEDs, but I believe that they are hardwired. Any ideas are appreciated. What I found so far is that if the relay pin is set to PWM and I change the PWM value the color of the button switches between blue through purple up until the relay clicks and the button becomes red. Strange thing is that if I set the pin for the relay as a button the button becomes dim to my liking.

Moreover, after reset mcu sending trashes. I tried with many baudrates. Always sends random (readable or not readable) characters.
edit: My mistake. My cheeap USB to serial adapter has broken, because of high baudrate.

I just got logs after reset on 2000000 baudrate via logic analyser.

I have solution. My USB port in PC has some CC limit. Probbably USB current limit reset the moduel while is starting. (I powered the module via this port) After change to powerbank (for test) the AccessPoint works well. I love debugging... xD Bug is small, but so anoying. I spent few hours...

p.kaczmarek2 · Answer

I am happy to hear it's resolved. How did you power that device? USB port should be able to provide at least 500mA so I am suprised... maybe used LDO is the culprit?

chlebok · Answer

Exactly! The problem was with the D-Sun PL2303 (pl2303HXA) budget USB to UART adapter I had for years. Now I've just discovered there is only an internal 3V3 LDO on this board with 4mA current! (DS for pl2303HXD)

p.kaczmarek2 · Answer

Well, I would say that this has no chance of working. I am always using an external LDO, AMS1117-3.3V or TC1264-3.3V, which can provide enough of current, you can see that on our guides:

I see

I have another problem. LiteFS doesn't work. Can't create file or do nothing else in FileSystem tab. No correct response. (I compared with working OBK)
I tried in console with results:

Error:CMD:cmd lfs_mount NOT found (args )
Info:CMD:[WebApp Cmd 'lfs_mount' Result] Unknown command

p.kaczmarek2 · Answer

LittleFS is not enabled on BL602 due to the small size of memory on this chip. You can use Short startup command instead.

Hello and thank you all for the comprehensive information. I have successfully flashed my devices (2 and 3 gang). Before flashing, I make original firmware dump. If anyone is interested, I am attaching it below. Also, I attach detailed photos of these products.
