#30 Internet of Things with ESP8266 #2: Physically Programming ESP-12

How do you program an ESP-7 or ESP-12 module if it is soldered onto a PCB in your "Thing"? In this video I show my proposal using pogo pins.
I also show how I create the timing to set the ESP8266 automatically into programming mode if the Arduino IDE starts to upload. For this solution, I use an Attiny85.

Dear Andreas, I am an avid viewer of you channel, and love your contents very very much. They have helped me out of many ditches (that I had dug for myself.)

So, I would request you to please make a esp 12 programmer without an ATTiny.
Thank you. (Stuck in yet another ditch)

Thank you so much for making this video. There is a lot of misinformation out there, and you explained in a short & easy way.

[ankersman]

Your videos are fantastic! Your explanations are very clear. Every sentence packed with high-value content. Thanks heaps!

[elimareyev]

Very nice video, Andreas! I'm guessing the next step would be Over-The-Air sketch uploading? Keep up the good work!

[zhixiangyuan]

Really good, hope you can continue to make more video about ESP8266

[josecunha]

...excellent video. So grateful for the help. Very informative.

[Aemilindore]

You know, the creators of ESP must pay you for doing this.

Grüezi Andreas, super video! Ich benutze einen FTDI FT232RL, diesen USB adapter hat einen RTS und die RX-TX sind 3.3V, sehr bequem beim programmieren.

Nice video and i very interested to ESP8266 modules keepup

[kianpengyong]

Very clear video. I managed to upload the *blink* sketch via Arduino IDE but once upload completes, what do I need to do to initiate normal run? Do I need to disconnect GPIO0, GPIO15 ... connect RESET to Vcc ... Disconnect EN ...etc? Thank you very much.

I see your USB <-> serial adapter has the CTS pin and from what I can tell that should also be manually controllable as an output. Couldn't that replace the RTS pin for programming?

Hello I adjusted my LM2577 Boost Buck convertor 3.3 V via potentiometer. My connection. Vcc--10kOhm--CH_PD Vcc--10kOhm--REST GPIO15--10kOhm--GND GPIOO--10kOhm--Vcc. But when instrument ESP12E Vcc and GND. I see 2.5 V 2.7v. Why voltage dropping occur?Im thinking about doing adjust the potentiometer until the see 3.3v multimeter screen but Im avoid the adjust SMPS when it was power on.I assume it will be easily damaged the esp. Can you help me?

[marinehm]

I have problem. I want to use a WEMOS D1-mini as a wifi extender. I know it can do this but, if there are more than one SSID, I may have just answered my own question. Log onto the wifi/SSID I want to extend and then broadcast the same SSID? You think you could maybe make a video explaining this? Thank you so much for ALL your videos. I have learned a lot from them over the last year.

[robertogarcia]

Hello,
What's the name of the module with the build in adapter?
Thank you in advance

Hi Andreas, I am enjoying your series of videos on the ESP8266. So much that I bought one to play with. However, I can no longer find the code for the Attiny85 timing sketch on Have you got the code anywhere else?

[msmadaram]

have you ever work on android broker such as moquette or something like that ?

when we have one esp8266 and we want to connet to it with 20 mobile phone what happen?
each esp8266 or esp 12e can just have 8 TCP/ UDP connection

what's your idea if we have 20 mobile phones and simultaneous they want to connect to one esp publisher?

if we run an android broker on one of mobile phones and other connect to it we can connect to esp by one TCP/UDP from broker to esp, is it true?

have you ever work on android broker such as moquette or something like that ?

and we don't have any cloud on the net!!!!

[ScottSymes]

Could you please share your ATtiny code for the program timing?

[Dharmendrasavaliya]

Sir, i have issue regarding Flashing NodeMCU
After flashing with ESPFlasher ....
ESplorer shows that "Can't autodetect firmware, because proper answer not received."
and END without showing firmware version..
what should be issue?

[Pratik_Somaiya]

Hey!! Thank you so much, It helped me a lot!!
