Hi Manuel.
I would suggest following other examples to send data over serial.
This tutorial is outdated.
I would recommend examples using Arduino IDE instead of LUA.
Regards,
Sara

I would like to read out and evaluate the RFID reader RDM6300 with the ESP8266.
Hoped this script would work for it, it doesn’t work.

Do you know a Lua script that works with the RDM6300 RFID reader?

greeting
Manuel

The paragraph called “Final Circuit” is only a Fritzing schema and doesn’t show this essential information. Add this and the (good) article will be complete!

I would still need clarification on the steps to follow.

I am trying to do the sensor data acquisition on an atmega328 the same as on the Arduino uno.
These data will then be transmitted to the esp for my part an esp-wroom-02 based on esp8266Ex which will be responsible for connecting to the internet to display my data in an application.

Questions:
– is the FTDI only used to load the code that will allow the processing of data in the ESP?
– the ESP and the Arduino are well connected by the TX and RX pins?
– how could I put the esp to sleep to wake it up only when data is present on the serial bus (TX, RX).

Thank you.

I have installed it on MacBook Air and I have connected the FTDI Programmer to the ESP01.
Would appreciate if you let me know what’s happening.
There is a small red led lit up on the FTDI programmer as well as the LED on the ESP01 also lit indicating the power to the ESP 01 has been provided.

I tried on both the com ports of my mac . No response.
Also in the right panel of the ESPlorer there is an Open button, if I click on it – I see a “Communication with MCU” and then nothing happens. (The Open button changes to Close thats all) when I click on the Close – then I see a “PORT CLOSED” message

Hi.
Unfortunately, we don’t have any tutorial on that subject.
Regards,
Sara

I’m pretty much in the same boat.. But, running both Windows & Linux (preferably linux..)

Thank you Josh.
I’m glad I could help!
