That's great news, can we now make a DIY ESP8266 board with 8MB flash chip, etc?

Amazing news!! Flashing went smooth, confirmed WiFI is not resetting after connecting to network, after manual reset all good, GPIO2 works 🙂 Code: text Expand Select all Copy to clipboardInfo:MAIN:Time 4156, idle 0/s, free 32560, MQTT 0(260), bWifi 1, secondsWithNoPing 4090, socks 0/0  Info:MAIN:Time 4157, idle 0/s, free 32560, MQTT 0(260), bWifi 1, secondsWithNoPing 4091, socks 0/0  Info:MAIN:Time 4158, idle 0/s, free 32560, MQTT 0(260), bWifi 1, secondsWithNoPing 4092, socks 0/0  Info:MAIN:Time 4159, idle 0/s, free 30648, MQTT 0(260), bWifi 1, secondsWithNoPing 4093, socks 0/0  Will test more but super cool!!

Fixed OTA, problem was partition layout. Apparently ESP8266 had a problem with offsets. Need 1MB flash test. A question: What platforms need PWM duty update every 25ms? I had to hack ESP8266 and ESP-IDF pwm code so that it would update duty only once. Otherwise it spams the console.

Merge-ready, i believe. Added powersave (enabled by default from SDK) Added deepsleep with timer (it shuts down, but doesn't wake up for me) Fixed 1M build. No gpio deep sleep on SDK side.

And another idea for device-hosted web app: If we could somehow enable Content-Encoding gzip specifically for web app page/scripts, then they could be stored precompressed.

>>21597649 Imagine a webapp running on that little gateway (8Mb of space) as well + zigbee + BTHome... how nice would that be??

insmod · Answer

Added PWM and UART, fixed Wifi first connect and reconnect. UART RX had to be done very primitively, this in a task: Code: text Expand Select all Copy to clipboardwhile(1) {    int len = uart_read_bytes(uartnum, data, 512, 20 / portTICK_RATE_MS);    if(len)    {       for(int i = 0; i

>>21596138 WiFi is fixed, confirmed. PWM is Inverted, but working. PWM_n works as expected (also inverted) Smooth transition also works, flag 18 Can't check UART now. Code: text Expand Select all Copy to clipboard[00:43:42]Info:MAIN:Time 411, idle 0/s, free 27140, MQTT 0(26), bWifi 1, secondsWithNoPing 344, socks 0/0  [00:43:43]Info:MAIN:Time 412, idle 0/s, free 27140, MQTT 0(26), bWifi 1, secondsWithNoPing 345, socks 0/0

DeDaMrAz · Answer

That may be a remnant of the IR testing way back on Beken N. Added after 1 [hours] 46 [minutes]: Confirmed! Pin setup is retained will check more later.

p.kaczmarek2 · Answer

Nice progress! I think we can move PWM update to be done only on change.

p.kaczmarek2 · Answer

Does it support OTA from Tasmota? Or not, due to partitions difference? I we wanted to run it with 8MB flash, we need to partition table, like platforms/ESP8266/partitions-2mb.csv ?

DeDaMrAz · Answer

I wanted to ask that question as well. After digging through my pile of module I have all sorts of chip sizes and of course various flash chips as well that I can add.

insmod · Answer

>>21597058 Tasmota uses Arduino framework, which uses NONOS SDK, incompatible with RTOS SDK. There is a possibility to OTA from Tasmota, but firmware must be built manually with this guide: What to do with 8mb flash? Max firmware size, from what i remember, is 1MB. 6mb LFS?

DeDaMrAz · Answer

WebApp on a device or something of that nature for example.

insmod · Answer

Well, web app needs about 300kb for a full dist (287278 bytes in my example, after i cut startup.js a little to remove all folders, as i'm not sure if they work in OBK). That means that it could be loaded on all bekens, LN882H, RTL8710A, 8mb or more RTL8720D, barely on BL602 (with new partitions, on old it fits fine) and almost on RTL8710B (it has only 274432b). I tried it in my WBRG1 and it works. Of course if it was minified, it would probably fit on every device (at least minus ~11kb just by minifying templateParser.js and httpVueLoader.js).

DeDaMrAz · Answer

Idea is to expand it with more features so space is always welcome ( like GPIO doctor for example) webapp is somewhat neglected for some time now. On the other hand that WBRG1 has BT and as mentioned before BTHome would be a massive plus for that gateway, and BT in general is a better feature than webapp across devices in my opinion. Data logging is another feature that was talked about. Another opinion of mine is that we have reached a super wide coverage of devices and we should maybe focus on polishing UI and UX across the board. New features, drivers etc per request and finally doing per device build. I am making a small cluster that possibly can be used for testing that so after deployment we can expand on that topic if it is of interest of course. Again just my opinions.

insmod · Answer

Completely minified web app weigh 195261 bytes. Older vue.min.js allows for additional ~7-8kb size reduction. On what it wouldn't fit: ECR6600, ESP8266, 2mb ESP-IDF, all XRs, RTL8710C, W800, W600 I like UI as it is now, minimalistic and fairly easy to understand. I plan to experiment with BT after i port RTL87xxDA (AmebaDplus, Tuya WR11-series, I shelved OPL1000 for now). Or perhaps after i try to create easyflash config generation on windows.

DeDaMrAz · Answer

Nice on the minification! It's not that I don't like the UI but if you browse issues or PR's for a bit you'll find so many similar questions regarding UI, webapp, overall UX that is not that welcoming to new users. For example we got some legacy stuff still lingering on the home page, this comes to mind Code: text Expand Select all Copy to clipboard(Cfg size: 3584, change counter: 6, ota counter: 1, incomplete boots: 1 (might change to 0 if you wait to 30 sec)! Not to mention flags... which I personally like but for new users they are confusing AF. This project is dependent in a way from new users so we might as well pay more attention to them and got some of those complaints resolved. AmebaDplus can be a nice addition but I was ready to bet money that OPL was next 😁 I must stress again, I am just thinking out a loud! P.S. thank you for suggesting another device to look for 😁also to suggest this board as it should be pin compatible with Dplus -

insmod · Answer

>>21597087 This board uses T2-U, which is just CBU with a different name (T2 is Tuya-flavored BK7231N). Didn't you already have a BW20 module? It is RTL8711DAF (Dplus). After Dplus, i'll probably port RTL8720E (AmebaLite), since it uses the same SDK. RTL8720ECF: Additional challenge for me - to port without modifying anything in SDK, like i've done ESP-IDF.

DeDaMrAz · Answer

At this point I have no idea what I have in the box of modules, yesterday I found a W600 module that I forgot I ever ordered, so... maybe 😁 But as every good alpha tester I'll order some more of course 🙂 pair of each because science! What stalled on OPL? I've seen some sonoff devices in the wild using it

insmod · Answer

>>21597094 The lack of AP mode. You did have BW20, i remember you posted an ali order screenshot with it.

DeDaMrAz · Answer

You made me look!! And yes, you are 100% right, I have them all... even some exotic ones..

insmod · Answer

And you also have RTL8720ECF module

DeDaMrAz · Answer

Yeap, all of them... Remember I was absent for more than 6 months... because life, and work, and shit... completely forgot about it all. I've been playing catchup for last couple of days, maybe weeks - not even close to get the hang of things.... Thank you for the reminder!

divadiow · Answer

tried anyway to see what it would do. same with Tasmota and Tasmota-4M Code: TextLog in, to see the code Added after 8 [minutes]:cool. OTA log Code: TextLog in, to see the code

p.kaczmarek2 · Answer

I like current UI as well. Maybe we could try to flash WebApp automatically with BK7231 Easy UART Flasher, but auto-download button/mechanism seems easier. We may also consider adding this change to all platforms: This seems to make LFS faster with no real drawbacks at all

DeDaMrAz · Answer

I think I was misunderstood about the IU - I like it as well and don't want to change it in general just to touch upon it and remove some legacy stuff for example and provide some new information on there. My idea originated from tasmota and how it handles internal chip temperature - with a setoption146 flag/command. Maybe it can be done in OBK in a similar fashion, as I remember there are some chips that don't have internal temp probe, so we can move those new features to a flag for example. Again to ping @max4elektroda whose idea on that topic I liked (not tested by me). And on the polishing UI I was talking mostly about some features that I personally find annoying and answering the same questions from time to time - for example Code: text Expand Select all Copy to clipboardwhy does it take two back click to go back from config to home page?? Or Code: text Expand Select all Copy to clipboarddoes flag 37 actually work?? Those kind of things can (I think) improve on UX just by little tweaks on the UI. I think I am capable of testing almost anything in OBK at this point and I volunteer to test and verify whatever need be.

p.kaczmarek2 · Answer

Gzip may be a good idea. The header is not compressed, and it still plain text, it looks like somewhat like that: Code: text Expand Select all Copy to clipboard HTTP/1.1 200 OK Content-Type: text/html Content-Encoding: gzip Content-Length: 1234 Then compressed payload follows. Maybe we could add some kind of internal mechanism to LFS access, for example, when MyScript.vue is requested, LFS checks first for MyScript.vue.gzip and if present, returns it as a compressed stream, otherwise fallbacks to default behaviour. We would just need an Upload GZIpped button on LFS page. Added after 1 [minutes]: PS: Here is a little LFS profiller, I will add it to web app soon: Code: HTML, XMLLog in, to see the code
