To buy the ESP32 dev-board click Here. New version of ESP32 dev-board is coming! The new board will be ready for retail in few days. The new board is smaller than the old one, and has more pins. Download the DOIT dev-board schematic here. For more details, view LuaNode wiki page. For details, see LuaNode wiki page Here. See LuaNode wiki page Here. See wiki page Here. Note: There is a task to receive uart input. You'd better alloc more than k memory for this task, since the lua command handler will be called in this task, more memory is required for lua handler.

Set baud rate to pbs, using UART0. It will disconnect WiFi connection. The sample will let Alexa to do more things with ESP She will answer you "Discovery starting Once you are able to flash the firmware properly in your ESP then you can start building your applications based on embedded C very easily.

NodeMCU by default refers to the firmware although it encompasses a complete open-source IoT platform including firmware,documentation and a development kit based on ESP12E module. As of now NodeMCU is maintained as an open source project with great documentation and an awesome online community to help you in every step.

An ESP board. NodeMCU devkit already has the convertor in the board. But due to resource constraints of the ESP SoC we need to select the required modules and build the firmware to be flashed.

Fortunately there is a cloud based build service available to do the same job NodeMCU Cloud build service. It has a nice UI where user just needs to select the required modules and the cloud service will build the files.

By default the basic modules will be pre-selected. Select the necessary modules which is required for your application and click on Start your build. You will receive the build files via e-mail within an hour. Add this and the good article will be complete! Hi Manuel. I would suggest following other examples to send data over serial.

Thanks Rui, that solved it, I have a lot to learn. Melvyn Reply.

Awesome Melvyn! The ESP has four inputs that manage the startup behaviour. These setting are necessary to flash the chip! The GPIO0 setting now decides between run mode and flash mode. Connect a 10 KOhm resistor between 3.

This sets the ESP into run mode. The fourth is the "reset" pin. It should be on "high", so put a 10 KOhm resistor between Vcc and reset pin. It's an "enable" pin you may use to switch off the whole ESP-Chip. Devices with an embedded ESP-Chip Sonoff basic or 4ch for example will have these resistors on board. Just GPIO0 has to be set to ground with a jumper bridge or via a pushbutton. Install the serial monitoring program of your choice.

Plug in the UART and open the device manager. Remember the settings mentioned under some basics about flashing above. Now it depends a lot on what ESP you use. Connect the power supply to Vcc 3. If using higher voltage power supplies, use a voltage regulator! Watch out not to swap the leads accidentally - it will kill the ESP. Double check your cabling! All connections made properly? Check against section above.
