Connection lost when multiple publishers send data to mosquitto broker on raspberry pi 3

Hi,

I have successfully done one publisher and one subscriber example by using mosquitto broker on raspberry pi and 2 nrf52832s. What I want to do is that I want to send data with different topics from 2 nRF52832s. When I tried to get data from only one publisher it is ok, but when I connect the second publisher the first one's connection gets lost. I could not notice what is the problem. May you please direct me to possible errors?

Best regards,

Halil

  • Hi Halil,

    I read that you can successfully keep a connection with both devices, publisher and subscriber. I'm trying the same but I can't. I mean, I can't keep a multiple client connection (one device at time, publisher or subscriber, works good).

    I can use the command "echo "connect XX:XX:XX:XX:XX:XX 1 ...." for both nrf52832 (works), but after that I can't proceed to establish a MQTT communication with publisher and subscriber to the Raspberry PI 3. LED 1 is ON in both device and buttons doesn't work for any device.

    I tried with SDK v15.3.0 and SDK v15.2.0; Same issue.

    Can you give me a hand, a guide maybe, please?

    Best regards,
