les adjunto el codigo que he hecho para las pruebas del sensor unicamente:
Código:
package com.example.pruebarfid2
import androidx.appcompat.app.AppCompatActivity
import android.os.Bundle
import android.widget.Button
import android.widget.Toast
import com.rscja.deviceapi.RFIDWithUHFUART
class MainActivity : AppCompatActivity() {
private val rfid = RFIDWithUHFUART.getInstance()
private var isInventory = false
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_main)
val button = findViewById<Button>(R.id.button)
button.setOnClickListener {
Toast.makeText(this, "Hola!", Toast.LENGTH_SHORT).show()
uhf()
}
}
private fun uhf() {
val result = rfid.init(this)
if (!result) {
Toast.makeText(this, "Conexión fallida", Toast.LENGTH_SHORT).show()
return
}
Toast.makeText(this, "Conexión exitosa", Toast.LENGTH_SHORT).show()
// Configuración de parámetros
// rfid.setFrequencyMode(xx)
// rfid.setPower(30)
if (rfid.startInventoryTag()) {
Toast.makeText(this, "Lectura iniciada", Toast.LENGTH_SHORT).show()
isInventory = true
ThreadInventory().start()
} else {
rfid.stopInventory()
Toast.makeText(this, "Error al iniciar la lectura", Toast.LENGTH_SHORT).show()
}
// ..............
rfid.stopInventory()
isInventory = false
// .................
// Desconectar UHF
rfid.free()
Toast.makeText(this, "UHF desconectado", Toast.LENGTH_SHORT).show()
}
private inner class ThreadInventory : Thread() {
override fun run() {
while (isInventory) {
val uhftagInfo = rfid.readTagFromBuffer()
if (uhftagInfo == null) {
Thread.sleep(20)
continue
}
val epc = uhftagInfo.epc
val rssi = uhftagInfo.rssi
// .....
}
}
}
}
y les dejo el error en consola cada vez que pulso el boton para la lectura del tag:
