trying to connect flespi.com to thethingsnetwork via mqtt. Did not work. So i startet to use some mqtt clients to connect to thethingsnetwork to find out what could be the reason.
last tool i tested is the “mqtt explorer” for OSX (see screenshot).
I used the appid (hilltronic2) as username and the access key! (starting with ttn-account-v2) but it always fails to connect or connection is refused
Any idea what i am doing wrong?
I thought mqtt is that simple standard protocol :-))
Thanks for help
