Logs

While logs are normally sent over MQTT, any logs that are created before WiFi-connection are sent out on Serial. If you wish to see the logs going over MQTT, you can look at the topic nspanel/<panel name>/log.

If you wish to look at the logs going over serial, you can use programs like Putty.

Connect to the NSPanel with the serial programmer as usual but don’t connect IO0 to GND.

In Putty enter your serial port in the "Serial line" box and choose baud 115200.

You should then be able to connect by pressing the "Open"-button.

info

On Windows /dev/ttyUSB0 will have to be replaced by something like COM4. If using MacOS or Linux the port will be something similar to /dev/ttyUSB0.
