Data Size Not Match 7 error ESP32

Hi,

I am using an ESP32-WROOM-32UE and an E32900T30D.

I run this code: /*
* LoRa E32-TTL-100 – ESP32
* Configuração do módulo e leitura das informações
* Adaptado para usar os pinos 16 RX e 17 TX
*
* Conexões:
* M0 —– 3.3V
* M1 —– 3.3V
* TX —– GPIO 16 pull up resistor
* RX —– GPIO 17 pull up resistor
* AUX —– 3.3v pull up resistor
* VCC —– 5V
* GND —– GND
*/

#include “Arduino.h”
#include “LoRa_E32.h”

// Define pinos de comunicação UART2 (ESP32)
#define RXD2 16 // Pino RX do ESP32 (conectado ao TX do LoRa)
#define TXD2 17 // Pino TX do ESP32 (conectado ao RX do LoRa)

// Inicializa o módulo LoRa E32 usando apenas o Serial2
LoRa_E32 e32ttl100(&Serial2);

delay(500);
Serial.println(“Inicializando LoRa E32…”);
