You’ll also have to type blank lines to create proper paragraphs; just pressing Return once and then typing a new block of text right below a previous block only creates a so-called line break, which might be harder to read. Leaving one blank line between two blocks of texts nicely… so the forum is readable from a phone … Thanks in advance. 🤣 ---

The pins im using are: // Pin mapping const lmic\_pinmap lmic\_pins = { .nss = 10, .rxtx = LMIC\_UNUSED\_PIN, .rst = 7, .dio = {2, A2, LMIC\_UNUSED\_PIN}, }; and im using lmic abd example. I think i have tryed avery combination of keys format (the mbr… ) whats the right format for the NWKSKEY[16], APPSKEY[16] and u4\_t DEVADDR? Another question i have, is i want to get more information about how to transmit and receive ttn packages in a node. Is it any place to get started? Thanks in advance ---
