@@EspenShampoo25 I think the biggest, or maybe only, problem with D1-clones is the voltage regulator. Original Wemos use ME6211 with 500mA, clones mostly have a regulator with SMD-Code 4A2D. The most power-consumpting part is Wifi and i tried capacitors at 5V and/or 3.3V, but only on 5V the result was a stable Wifi-AP, even i used a real 2A Powersupply. Without capacitor i had exactly the same behavior described in this video. After i soldered a capacitor (47uF, maybe less also ok) on the board between 5V and ground, Wifi runs rock-solid as client or accespoint. I have no Oscilloscope to visualize the efficience of this capacitor, but for me it works.
Hello. I have a problem with connecting to the AP. I'm going to upload the program pretty well to wemos. But if I connect with my smartphone and press a command, the AP stopped ... why? Servo board is well, servos too,... but communication between board=wemos=smartphone... no ... :( i tried cables and others... and nothing :/
@@MusaWilmar the tension is fine, I measured it. The code from you from the page is fine on your device. I'll join wemos without any problems. But as soon as I press a different command (run, walk ...), the wemos stops blinking and only shines. The site can then neither be restored nor anything else. And as for the servo board, I don't know any further.
@@tomminihillus4728 is your wemos stop broadcasting after you push a button? do you ever try detach all the cable from wemos and run it? is it have the same result? if not maybe you have short on your servo driver or servo...
try this: 1. run only the wemos and run serial monitor from arduino IDE @115200 baud rate 2. open the webpage and push one of them 3. on your serial monitor should show some code (just one time) 4. one thing that u have to known is every command u send to the servo driver need feedback from driver that's move is done. but because u don't attach the RX/TX cable to servo driver it will wait the OK signal eternally (it's normal) 5. than connect RX/TX to the servo driver and power it again 6. repeat the step 2, you will able to send more than 1 click button (it's mean that your driver is OK too) 7. than connect your servo one by one and repeat the step 2 until all servo connected.
@@MusaWilmar yes i do it and the result is the same. It was connected only from USB and I connected to it without any problems. When I pressed a command, it stuck again and stopped flashing / loading.
I HAVE FIX THIS ISSUE FOR www.instructables.com/id/Simple-NodeMCU-18-DOF-Hexapod/ and for www.instructables.com/id/ESP8266-WIFI-AP-Controlled-Quadruped-Robot/
did u try simple AP webserver first..? just to make sure that your board can use that protocol... PS: i'm using chrome on android too... and it's work really good... but also there some board didn't work...
@@georgegabriel7766 there is many example on internet how to make nodemcu AP webserver, maybe u can use this one because it's look similar with mine www.teachmemicro.com/web-server-nodemcu-websocket/
good video about common AP problem, keep posting and sharing
Kereeen, mantaab 😂
I have order two of D1 both are similar i have installed ch340 driver one of the support but still one not showing or connection with my computer
Since i placed a 47uF-Elko on 5V my D1 mini clones are stable in AP-mode.
Could you ellaborate on that please. I am having some issues with unreliable wifi on a project i am making.

@@SniffinGlueDE thanks alot man. Ill try it out fir myself once i get ahold of a capacitor!
nice... thanks for your information.....
@@SniffinGlueDE Great!! I was thinking about doing that, hands to work!
so the clone is not working?
common problem with cloned products..

check your power, maybe it's under power

What did you change?
@@tengelgeer change the wemos with a good new one
@@MusaWilmar haha, okay. I assumed something in code 😅
Try this:
1. From Arduino IDE menu, select Tools -> Erase Flash: "Only Sketch" -> change to "Sketch + Wifi settings"
2. Compile & upload.
3. Revert the settings. Go to Tools --> Erase Flash: "Sketch + Wifi settings" --> change to Erase Flash: "Only Sketch"
4. Compile & upload again :)
@@davidwicaksono Thanks, i will try it
the clone problem sometimes
I tried 3 boards so far and none of them worked. I can connect to the WiFi but none of them ever render a page. I'm using Chrome on Android
did u try simple AP webserver first..? just to make sure that your board can use that protocol... PS: i'm using chrome on android too... and it's work really good... but also there some board didn't work...
maybe it's because bought cheap nodemcu from china...

@@georgegabriel7766 no special setting just like any other wifi AP, just user and password to connect... And open the web page...
Cara fix nya sudah ketemu om?
kalau itu memang masalah di HW nya... klo clone memang agak untung untungan...
@@MusaWilmar kalau erase flashnya ubah jd yg sketch + wifi itu udah coba?
uhhh , um get ummm uhhhh to, umm the,, fucking uhh POINT
Just ignore me if u don't get any point... Anyway thank you for your comment...
