Ubuntu preparation
First we installed the mosquitto client: sudo apt install mosquitto-clients

Host file:

Add the N870 to your host file in case you want to use a DNS name. (/etc/hosts)

Code Block
languagebash
127.0.0.1       localhost
127.0.1.1       Int-VirtualBox
192.168.178.192 int-589ec60e71c0

2. How to see the MQTT response

Scroll to top

Before you start sending the first location request, you would also like to see the response of the Cordless system.

If you want to see the MQTT communication/response from the N670/N870 you can do this by opening a new command line window on the Linux PC and enter the command.


Code Block
languagebash
mosquitto_sub -u as1 --psk-identity as1 --psk 123456789012345678901234567890ab -t +/+/as1/pos/# -p 8884 -h 192.168.178.190 -v
