	Use [[Arduino_radio_hc-12#Terminal_program\|PuTTY]] and save (stream) logs to a file. Works like a charm. The notepad++ can be set to update automatically without asking (Ctrl-R reloads the file) by using <code>Settings -> Preferences -> MISC. -> Update silently</code>, but it still need Ctrl-R to reload the file.		'''RealTerm''': Serial/TCP Terminal (https://sourceforge.net/projects/realterm/) by Crun is a rather easy and good behaving serial port logger with timestamps. It also shows the name of peripheral attached to the COM (USB) port. It can show also the I2C data.



			'''Putty:''' cannot add the timestamp. There are some extraplugins, but I will skip those. Use [[Arduino_radio_hc-12#Terminal_program\|PuTTY]] and save (stream) logs to a file. Works like a charm. The notepad++ can be set to update automatically without asking (Ctrl-R reloads the file) by using <code>Settings -> Preferences -> MISC. -> Update silently</code>, but it still need Ctrl-R to reload the file.

	However, Grafana cannot update a local file. Instead use a web server (eg nginx) to serve the CSV files over http and then use http url (eg http://localhost/my-csv-app/my-csv-file.csv).
