Problem with installation Lora Gateway and PirBOX-LITE

[zaratustraelimpio]

Hi,
I am trying to carry out this project with the PIRBOX-Lite and the LilyGo LoRa Board gateway (https://github.com/PricelessToolkit/MailBoxGuard) but it is not working for me (in HA the MQTT does not recognize the PIRBOX-Lite). I load the LilyGo LoRa Board code correctly and in MQTT it recognizes it perfectly:

But when it comes to uploading the PIRBOX-Lite code, I cannot see it in MQTT. I see how the LED lights up every time it detects movement but however this entity does not appear in MQTT. I have the feeling that the gateway is not communicating with the PIRBOX-Lite, could someone help me? I have these configuration parameters set, do I have to set different ones? thanks.

(1) config.h Gateway:

`/////////////////////////// LoRa Gateway Key ///////////////////////////

#define GATEWAY_KEY "x" // Keep it Tiny

////////////////////////////// WIFI / MQTT ////////////////////////////////////

#define WIFI_SSID "RBB"

////////////////////////////// LORA CONFIG ////////////////////////////////////

// For sending 6 bytes "6 characters" of data using different Spreading Factors (SF), the estimated time on air (ToA)
// for each SF is as follows:

// SF7: Approximately 0.027 seconds (27.494 milliseconds)
// SF8: Approximately 0.052 seconds (52.224 milliseconds)
// SF9: Approximately 0.100 seconds (100.147 milliseconds)
// SF10: Approximately 0.193 seconds (193.413 milliseconds)
// SF11: Approximately 0.385 seconds (385.297 milliseconds)
// SF12: Approximately 0.746 seconds (746.127 milliseconds)
// These calculations demonstrate how the time on air increases with higher Spreading Factors
// due to the decreased data rate, which is a trade-off for increased communication range and signal robustness.

#define SIGNAL_BANDWITH 125E3 // signal bandwidth in Hz, defaults to 125E3
#define SPREADING_FACTOR 11 // ranges from 6-12,default 7 see API docs
#define CODING_RATE 6 // Supported values are between 5 and 8, these correspond to coding rates of 4/5 and 4/8. The coding rate numerator is fixed at 4.
#define SYNC_WORD 0xF3 // byte value to use as the sync word, defaults to 0x12
#define PREAMBLE_LENGTH 12 // Supported values are between 6 and 65535.
#define TX_POWER 20 // TX power in dB, defaults to 17, Supported values are 2 to 20
#define BAND 868E6 // 433E6 / 868E6 / 915E6

(2) Config.h PirBox-Lite:

`/////////////////////////// LoRa Gateway Key ///////////////////////////

#define GATEWAY_KEY "x" // Separation Key "Keep it Short 2 letters is enough"
#define NODE_NAME "Buzon" // Sensor Name which will be visible in Home Assistant
#define Encryption true // Global Payload obfuscation (Encryption)
#define encryption_key_length 4 // must match number of bytes in the XOR key array
#define encryption_key { 0x4B, 0xA3, 0x3F, 0x9C } // Multi-byte XOR key (between 2–16 values).
// Use random-looking HEX values (from 0x00 to 0xFF).
// Must match exactly on both sender and receiver.
// Example: { 0x1F, 0x7E, 0xC2, 0x5A } ➜ 4-byte key.

/////////////////////////// LORA RADIO CONFIG ///////////////////////////

#define LORA_SYNC_WORD 0xF3 // The 0x1424 private sync word is equivalent to the CapiBridge 0x12 sync word.

// LoRa Sync Word Compatibility Table20
//
// This table shows how 16-bit sync words used on "PirBOX" SX126x-based modules (like Ra-01SH) correspond to the 8-bit sync words used on older SX127x-based modules.
//
// | Type | SX126x Sync Word | SX127x Equivalent | Notes |
// |---------|------------------|-------------------|---------------------------------------------------------------------|
// | Public | 0x3444 | 0x34 | Default for LoRaWAN. Reserved, do not use for private networks. |
// | Private | 0x1424 | 0x12 | Recommended for custom/private networks. |
// | Private | 0x1437 | 0x37 | Custom private network sync word. |
// | Private | 0x14A9 | 0xA9 | Custom private network sync word. |
// | Private | 0x14D5 | 0xD5 | Custom private network sync word. |
//
// Notes:
// - SX126x uses a 16-bit sync word, always starting with 0x14 for compatibility.
// - SX127x uses an 8-bit sync word, derived from the lower byte (0xYZ from 0x14YZ).
// - Avoid 0x3444 (0x34) in private networks — it's reserved for "LoRaWAN public" use.
// - Choose a unique 0x14YZ value for a private network to avoid collisions and improve isolation.
