I've flashed the opl1000_at.bin from https://github.com/Opulinks-Tech/OPL1000A2-SDK/tree/master/FW_Binary

The Ali door sensor binary is outside of that SDK path but does reference A2 https://github.com/Opulinks-Tech/OPL1000A2-Door-Sensor-Ali-Cloud

I'm not sure if A3 SDK is a revision of the same SDK as well as a version of the OPL1000 chip, so we should use updated A3 SDK or if each SDK is specifically for each chip type only. I note our chips have A2 printed on them.

Added after 3 [minutes]:

these are identical however
https://github.com/Opulinks-Tech/OPL1000A3-SDK/blob/main/FW_Binary/opl1000_at.bin
https://github.com/Opulinks-Tech/OPL1000A2-SDK/blob/master/FW_Binary/opl1000_at.bin

Added after 1 [minutes]:

each SDK readme does make a point of saying "OPL1000A3-SDK is Opulinks official software development kit for OPL1000 A3 chip" which reads like each SDK is specific to each chip revision

use GNU arm GCC tool. "Makefile" is provided for each individual example under SDK\APS_PATCH\examples folder. User can use Make tool to compile and link own application. How to install GCC development environment under Windows system please refer chapter4 of "OPL1000-SDK-Development-guide.pdf" document.

but maybe it would be easier to:

I tried first way.

In msys64 do, first update:
Code: text Expand Select all Copy to clipboard
pacman -Syu

then toolchain:
Code: text Expand Select all Copy to clipboard
pacman -S mingw-w64-x86_64-arm-none-eabi-gcc

then you should have:

Add to path:
Code: text Expand Select all Copy to clipboard
export PATH=$PATH:/mingw64/bin

Then try in path:

I added log:

Now I will try to compile:

This has been created:

It has elektroda in bin:

@divadiow can you try to retrace my steps and also get those binaries and then try flashing them?

hmm.

i've been playing with wpa_station and these are curious

[sys_cfg_rf_m0_set_impl 132] ipc_m3_msg_write fail
[sys_cfg_rf_init_patch 181] sys_cfg_rf_m0_set fail

I'm wondering about what the 128 or 256kb flash built into the OPL1000 contains, or did contain, from factory. Are some of the addresses in PatchData.txt used not correct? where is the RF data held? What effect does having the 8mbit flash in addition to the on-board memory have on PatchData.txt? Do the demos assume only the on-board flash is present?

There's vey little online about this chip as we know.

not sure of what this means though for the content of a patchdata file for a firmware that'll not fit on the OPL onboard memory

well exactly. my question back to them is about A1 vs A2. Maybe the silkscreen is OPL1000 series, but actually it's an OPL1200 and then it makes sense we should use the A2 SDK.

I have not tried any A1 SDK builds.

Well, both our photos shows "A2", when you look closely...

So I guess that's solved?

Sadly I don't have my one already (I was flashing a batch of devices for a friend and no he is using it with original cloud) so I may need to get another one soon.

Anyway, so in A2 SDK everything works so far?

ah. the function of the correct GPIO needed changing in hal_pin_config_project.h to PIN_TYPE_GPIO_OUTPUT_HIGH from PIN_TYPE_ICE_M3_CLK

then only the GPIO# in wpa2_station_app.c needs changing.

Code: Text
Log in, to see the code

It's clear from the traces and datasheet the LED is connected to GPIO21

and now LED lights when wifi is connected

hal_pin_config_project.h content is a product of the PinMux tool where the function of each GPIO can be set.

the highlighted files are created on PinMux build

ota:

If we can get ota_wifi demo working, we could try adding OBK to that.

Just how to get OTA file...

We will also need to think about the futher OTA usage. Can the OTA file be created from commandline? Our automatic Github builds will require that....

I will do the coding, once we have everything confirmed to work, but I don't know much about the build process on Github itself. Maybe we can just reuse the path of one of the other platforms.

Strange:

Did this device support AP mode pairing for the app?

But those comments seem to be related to separate functions, not to AP mode itself..

Here is some STA init code:
https://github.com/Opulinks-Tech/OPL1000A2-SD...amples/protocols/tcp_client/tcp_client.c#L235
Maybe we can change:
- wifi_config.sta_config to wifi_config.ap_config
- WIFI_MODE_STA to WIFI_MODE_AP

Added after 41 [seconds]:

Then it should create AP. The AP initialization itself is NOT listed as unsupported, so it should work.

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:

Topic summary

The discussion revolves around the Sonoff DW2 door/window opening sensor, which utilizes the OPL1000 WiFi microcontroller. Users explore the sensor's capabilities, including firmware modification and potential applications. Initial concerns about the sensor's functionality, particularly regarding its signal transmission during opening and closing events, are addressed. The conversation shifts to the development of OpenBeken firmware for the OPL1000, with participants sharing insights on flashing the device, compiling firmware, and troubleshooting issues related to OTA (Over-The-Air) updates. The group also discusses the differences between OPL1000, OPL1200, and OPL1600 chips, and the compatibility of various SDKs. Progress is made in getting the device to connect to WiFi and in implementing OTA functionality, while challenges remain in establishing an AP (Access Point) mode for configuration.
