Hi there,
I have two local clients (Controllinos, basically Arduino Megas) that have both different Mac-adresses set, different IPs and I can ping them both with immediate response (\<1ms).
As broker I have tried out the Mosca-node, which works well with only one client and aedes, where I get a "identifier rejected".
I have tried almost all possible ways to connect those two clients to the broker, so that I can see the data on the dashboard. But all I get is data off client nr. 2.
Maybe anyone has got some help for me?
Thank you in advance,
regards,
Jürgen
