trying to get the Grove - Wio-E5 tutorial to work. Ref: Grove - Wio-E5 - Seeed Wiki
Looking at the code I see that it references EU868 frequency I changed it to us915 with no luck. However, if I unload this sketch and manually enter the join code with the required id’s… it is able to connect to the TTN. There must be something else in the code I am missing and any suggestions would be good,
thx
