It would be useful to create a system to read the data entering the serial port using an Mqtt client
I see that in the router it is possible to activate a mqtt broker and a publisher
1 -How do I indicate that the publisher must be connected to the data coming from the rs232 port?
2- If we have another mqtt broker, such as Mosquitto, installed on our servers, is it possible to have the router's internal broker communicate with an external broker?
