allows the use of dynamically sized packets (packets can have payload lengths anywhere from 1 to 255 bytes).uses CRC-8 (Polynomial 0x9B with lookup table).can be downloaded via the Arduino IDE's Libraries Manager (search "SerialTransfer.h").The library is installable through the Arduino IDE and includes many examples. You can use SerialTransfer.h to automatically packetize and parse your data for inter-Arduino communication without the headace (including floats!). How can I solve this? Do you have similar simple example to show with SotwareSerial.h library? Thank You NodeMCU (ESP8266) //int data //Initialized variable to store recieved data Started SoftwareSerial at RX and TX pin of ESP8266/NodeMCU While if I try to transmit int values, this works with no errors.Īrduino #include //Included SoftwareSerial Library I'm receiving data in a float format but they do not have the decimal values. Īfter installing Tasmota to your board, go to the wifi settings on your laptop or mobile phone, you should see a WiFi device named Tasmota.I want to send from an Arduino float data to NodeMCU (ESP8266), without lose the decimals.
Yours should look something like this if you use Linux esptool.py -port /dev/ttyUSB0 write_flash -fs 4MB -fm dout 0x0 /home/pius/Documents/tasmota/tasmota.binįor more information on flashing Tastmota to esp boards visit here. Replace the part labelled com port with the com port your board is connected to and the part location of the.bin file to the location of the.bin file. esptool.py -port write_flash -fs 4MB -fm dout 0x0 After installing python open your computer terminal and type in pip3 install esptoolĪfter the installation type in the following command in the terminal, esptool.py -port erase_flash There are several ways to install Tasmota to your esp board but my favourite way is to use esptool, to use esptool you need python installed on your computer. To download the.bin file directly from Tasmota click here. Here are the links to download the Tasmota firmware. First, we will have to download the firmware. In the course of this article, you will be introduced to Tasmota and its most basic functionality, templates and how to create your own template.įor this article, I will be using the node MCU ESP8266 chip. Tasmota is very common and is compatible with various smart home platforms such as TUYA, Google Home, Home assistant etc. Tasmota is an open-source firmware created by Theo Arends for smart home devices using the ESP wifi chip.
