Can not use decoder in The Tings Stack (v3)
If I try to use the decoder I get:

i did it with the next code

this worked for me!

forget it, it worked with the simulated uplink, but not with the real uplink idk why :disappointed:
If i send 0188053797109D5900DC140802017A0768580673256D0267011D040214AF0371FFFFFFDDFC2E it does work, but when my device RAK7204 sends the uplink it doesnt work the uplink HEX is 799E4AE5A93A2B6E maybe is my device, but dont have that much of time to check it right now, that would make sense caause the uplink payload doesnt seems to be cayenne compatible
