No problem Felice, we all learn from our mistakes.
Only the first versions of the T-Beams needed that patch cable as far as I know. Here’s a pic of mine, notice it did not even had a version string at the usual location. You also can see in the little pin chart that only “Lora IO0” is mentioned, which means you needed to add that cable as I did (I wired DIO1 and DIO2 but only the former is needed for TTN usage AFAIK) :
And here is a pic of my other one which doesn’t need the patch wire. Notice if mentions pins connection for “Lora IO0” “IO1” and “IO2” :
Looks like it’s the same as yours.
