Having troubles flashing ESP-01 and ESP-12 through 2 different USB adapters

[sibianul]

Hello guys,

in the last years I purchased so many sensors and modules, and used so few but in the last months I started to put them to good use, so now I run out of WeMos D1 mini boards (which ware so easy to program) and the only boards I have are a few ESP-12 and one ESP-01. Today I wanted to connect 3 or 4 18B20 temperature sensors on the pipes of my gas heater and also an relay, so I will have my own thermostat controllable from my dashboard .

Can you guys tell me what I'm doing wrong, or what else do I need to do to be able to successfully flash and actually see the ESP_0 wifi network after reboot ?

On the ESP-01 I just made a bridge on the back side, between GND and IO0 to be able to flash it. It starts flashing, I get the message Success flashing and then, remove the bridge on the back and reboot. But I don't see any wifi to start configure it.
I also tryed nodeMCU flasher, but ith this it takes much longer to flash, and in the end it hangs up and in the LOG tab I see the error you see in the pic bellow.

On the other board, the ESP-12, I connected some female jumper wires from GND to IO0, from GND to IO15, from 3.3v to CHIP_EN as you can see in the bellow photo, and while flashing with ESPEasy Flasher I get the same success message at the end of the process, but after rebooting , I don't see any new wifi to set it up.
On this board I tried to upload a test program from the arduino IDE and it was successfull, it also connected to my network, and my Dashboard has notified me that new device connected to my home network. The device is working, but I don't know what's wrong when trying to flash using ESPEasy.

Do I need to have any pin HIGH or LOW to power on the ESP after flashing ?

Until you guys give me some advice's, I will try to play with the A6 GSM module, and the ESP-12, hope I can make it to send an POST or GET request to my server. I want to include a GSM gateway in my system, so in case of important alarms, or internet connection problems, I will get notified via SMS or from the same pushbullet service that I use now in my dashboard, but that BananaPi can't send notifications if the internet connection is down. BTW. Any plans in adding support to any (cheap) GSM modules ?

Thank you.

Hello,

at first the white board is not an ESP-12, it is an ESP-201.

Anyways.....
If i remember right the "blue" ESP-01 has 512KB memory, only the ones with black PCB have 1 MB.
The ESP-201 definitely has 512KB flash.

512 KB is no longer supportet - the smallest ESP-2.0.0 version is bigger then 512KB.....

Regards
Shardan

Ohhhh Thank's a lot Shardan for letting me know.

I will solder the ESP-12-E boards on the adapter board so I will easily work with them. I didn't knew the memory was lower on those models, I think those are the first ESP boards I purchased.

Wish you a good night.

You can flash older versions though.

I think on older version I don't have the HTTP GET option for my controller, I haven't yet setup and MQTT service in my Pi, as for me was easier to just make GET request, and process everything using PHP, an programming language I'm very familiar with. I remember when I first tried ESPEasy I needed to install the latest DEV version so I can have that HTTP GET controller.

Right now I'm so sad that my plans on adding an GSM module as a backup alerting system, for my HOME DASHBOARD are (temporarly) gone. Everything was fine with the A6 module I'm testing, I purchased an prepay SIM card from the most cheaper operator (but in the same time most advanced, not in terms of coverage, but in technology) .... the only problem they don't support 2G devices anymore, only 3G devices can connect to their network .. so my A6 GSM module is not going to send any ALERT or notification to me... The price of the SIM was only 2 Euro and it is active for 3 months, it also has 2Gb of internet traffic, more than enough for alerts and sensor values. The other operator SIM are much more expensive, each one starts from 5 Euro / month .. huge difference from 2 Euro / 3 months

This is it.. I will look over a 3G module to replace the cheap A6
