Added preference option to use the Home/End/PageUp/PageDown keys to scroll the terminal window contents instead of sending the corresponding keypresses via the serial port. Added Find menu item to find text in plain text view. Please refer to the platform specific '*** System Requirements.txt' document included with the download

the included 'Libs' and 'Resources' folders must reside in the same location as the CoolTerm application. Capability of saving and retrieving connection options.Д¬oolTerm comes without an installer and can be placed anywhere on the hard-drive as long as the correct folder structure is maintained. Configurable character, line, and packet delays. Capability of manually toggling line states of certain handshaking signals when hardware flow control is disabled. Hardware (CTS, DTR) and software flow control (XON). Local echo of received data (loop back to sender). Capability of capturing received data to text/binary files. Sending of text files via dialog or drag-and-drop. Sending data via copy-paste of text into the terminal window. Sending data via keypresses as well as a 'Send String' dialog that supports data entry in plain text or hexadecimal format. Display of received data in plain text or hexadecimal format. Capability of multiple concurrent connections if multiple serial ports are available. To send messages to the nodeMCU you can use the following channel,ДЄgain you need to replace the chip id with yours, what ever you post will appear in your console.CoolTerm is an easy-to-use terminal for communication with hardware connected to serial ports.Д¬oolTerm is a simple serial port terminal application (no terminal emulation) that is geared towards hobbyists and professionals with a need to exchange data with hardware connected to serial ports such as servo controllers, robotic kits, GPS receivers, microcontrollers, etc. You need a MQTT client application to send messages to nodeMCU form your laptop, I am using mqtt-spy.ДЇirst you need to subscribe to the nodeMCU publishing channel to receive the messages from nodeMCU.ДЎ0652610 is my node chip id, replace it with yours. Note down the chip id, you need it to send messages to the nodeMCU. You should see something like this on your console. Once you changed the parameters in a, you need to flash all the four files to nodeMCU and reset the board. a : NodeMCU will execute this file on startup, we will bootstrap the application using this file. a: This file contains the code to connect to your WiFiДЄpp.lua : This is where you will place your application logic, like controlling the IO pins based on the information received, and sending the messages to the desired channels You need to place your wifi name password,MQTT server name,MQTT user name (that you just created in step 5) and password in this file There are four files that you need to flash to the module.Д¬a : this file contains the information about the MQTT server ,WiFi details. Now your MQTT instance is ready to accept connections.

#Coolterm connection says clientclientclient full#

Please note that I am giving full access to the вЂњnodemcuвЂќ user, in production you should use more find grained ACLs

Save the new user, now we need to provide the ACL to the new user.

Create a user with name вЂњnodemcuвЂќ and give a password.

Click on details of the created instance and note down server address and port, we need them to connect to the broker.

Go to plansВ , and select the Cute Cat plan, signup if not already done.

coludmqtt provides a free instance which is good for exploring purpose.

#Coolterm connection says clientclientclient install#

whenever message is posted in the subscribed channel, we will post the status of the IOвЂ™s to the specified channel.ДЇirst we need a MQTT broker you can install the broker on your local machine and connect to it or use a cloud provider.

We will just subscribe to the channel and display the data published to the channel on the console.

In this blog we will see how to connect to a MQTT broker from nodeMCU and exchange messages.
