What am I doing wrong that fails to activate my device? Application version: 1.2.0 GitHub base version: 4.5.0
I've set Device EUI,Application EUI and App Key into se-identity.h as shown on the device overview.
The node never registers on TTN.
I even tried with chirpstack OS, the device never registers as well and reports a wrong MIC.
The gateway is right next to the node.

The issue is that you are configuring the wrong key on the end-device.

As it can be seen on the comment above APP_KEY it corresponds to GEN_APP_KEY which is mean to be used when handling FUOTA packages.

LoRaMac-node/src/peripherals/soft-se/se-identity.h

Lines 100 to 108 in 9a6c7dc

     { \  
   /*! \  
    * Application root key \  
    * WARNING: FOR 1.0.x DEVICES IT IS THE \ref LORAWAN_GEN_APP_KEY \  
    */ \  
   .KeyID = APP_KEY, \  
   .KeyValue = { 0x2B, 0x7E, 0x15, 0x16, 0x28, 0xAE, 0xD2, 0xA6, 0xAB, 0xF7, 0x15, 0x88, 0x09, 0xCF, 0x4F, \  
   0x3C }, \  
   }, \  

 

The key you need to setup is NWK_KEY

The secure elements on this project use the names defined by LoRaWAN 1.1.1 specification.
On top of the se-identity.h file you can see a correspondence table between LoRaWAN 1.0.x and 1.1.1

             The secure-element implementation supports both 1.0.x and 1.1.x LoRaWAN 
        
             versions of the specification. 
        
             Thus it has been decided to use the 1.1.x keys and EUI name definitions.

No need to feel something about it. It happens.

I have marked the topic as answered if you don't mind.
