Re: esp8266 esp-01

I have erased flash and reconnected the ESP every time before reuploading a new one. Another problem that I am facing is that during boot GPIO2 seems to be set to high. I have to manually deconnect the circuit there and reattach it after boot. Doubt this is normal behaviour. I think I will buy a bun...

Yeah images that didn't give me errors are The following are daily builds of the ESP8266 firmware. They have the latest features and bug fixes, WebREPL is not automatically started, and debugging is enabled by default. esp8266-20170719-v1.9.1-170-g46620061.bin (elf, map) (latest) esp8266-20170718-v1...

Re: esp8266 esp-01

Alright, thanks a lot for the help. I've managed to work a bit with the GPIO of the ESP with nodeMCU, but will check micropython, as well. I can't seem to find how to get the IP of the ESP. I want to build it as a simple server, but no idea how to connect to it. Seems to be bugged, so I went ahead a...

Re: esp8266 esp-01

Ok something strange happened. What I did was connect GPIO0 of the ESP to GND. Now both finding the ESP with esptool and picocom commands work(with parameters you gave), however esptool works only once and I have to reset the ESP with replugging power every time. Is this the correct behaviour, I won...

Re: esp8266 esp-01

Yeah I did that. If they are wired wrong the blue light doesn't blink, but once reversed it blinks on commands or when I use the esptool to search for it. Those fail, tho.

Re: esp8266 esp-01

Nothing. However, a small blue led clips on the ESP everytime I write a character in the console, but the character doesn't appear. No output whatsoever. This happens only if I reverse RXD and TXD cables. This is the wiring http://imgur.com/a/97eCn Maybe the firmware is bad and if I install a proper...

Re: esp8266 esp-01

Alright I went in advanced->serial-> "No" when it asks if you want a login shell over serial. It then tells me "The serial interface is disabled", there is no

Code: Select all

Say "Yes" when asked if you want the hardware enabled.
like in the steps you provided.

I have "enable_uart=0" in /boot/config.txt

Re: esp8266 esp-01

Sorry, I forgot to say, it's a Raspberry pi3b with Raspbian installed.

So I can flash the firmware through this, without USB ?

A small update, it finally got home to me and I've connected it to the pi. Similar to here Following this tutorial It seems I need to install the firmware on it, and since I'm doing it from the pi I chose esptool.py since nodeMCU is windows only. esptool.py expects as argument the serial port of the...

What I meant is something very simple that doesn't have to be accurate. Like the solution with two light beam sensors from above.

Couldn't find a simple example, most things that I found were already-made big projects. And they were on Arduino, too.

Sensor for direction of objects

I am trying to count how many people are in a room, and for that I was thinking of placing a sensor at the door that counts the direction of people - in/out of the room. What sensor can I use for that?

I mean there are movement sensors, but I need the direction in which the people are going to.

Re: Wireless circuit

ESP8266 modules are cheap and have built in WiFi. You'll need something like a small relay or optocoupler to close the switch contact too. You'll still need to run a wire to the unit for the switch and potentially one for power too unless you want to change batteries each month (if you are lucky) T...
