## El gateway no utiliza las configs para la potencia

Nuestra config de prueba:

"tx_gain_lut": [
      {"dig_gain": 0, "mix_gain": 11, "pa_gain": 3, "dac_gain": 3, "rf_power": 27},
      {"dig_gain": 0, "mix_gain": 13, "pa_gain": 3, "dac_gain": 3, "rf_power": 27},
      {"dig_gain": 0, "mix_gain": 9, "pa_gain": 3, "dac_gain": 3, "rf_power": 27},
      {"dig_gain": 0, "mix_gain": 10, "pa_gain": 3, "dac_gain": 3, "rf_power": 27},
      {"dig_gain": 0, "mix_gain": 12, "pa_gain": 3, "dac_gain": 3, "rf_power": 27},
      {"dig_gain": 0, "mix_gain": 10, "pa_gain": 3, "dac_gain": 3, "rf_power": 27},
      {"dig_gain": 0, "mix_gain": 11, "pa_gain": 3, "dac_gain": 3, "rf_power": 27},
      {"dig_gain": 0, "mix_gain": 11, "pa_gain": 3, "dac_gain": 3, "rf_power": 27},
      {"dig_gain": 2, "mix_gain": 12, "pa_gain": 3, "dac_gain": 3, "rf_power": 27},
      {"dig_gain": 0, "mix_gain": 13, "pa_gain": 3, "dac_gain": 3, "rf_power": 27},
      {"dig_gain": 0, "mix_gain": 15, "dac_gain": 3, "pa_gain": 3, "rf_power": 27},
      {"dig_gain": 0, "mix_gain": 10, "pa_gain": 3, "dac_gain": 3, "rf_power": 27},
      {"dig_gain": 0, "mix_gain": 12, "dac_gain": 3, "pa_gain": 3, "rf_power": 27},
      {"dig_gain": 0, "dac_gain": 3, "mix_gain": 13, "pa_gain": 3, "rf_power": 27},
      {"dig_gain": 0, "dac_gain": 3, "mix_gain": 15, "pa_gain": 3, "rf_power": 27},
      {"dig_gain": 0, "mix_gain": 15, "dac_gain": 3, "pa_gain": 3, "rf_power": 27}
    ]

De todas formas se transmite con 14 dBm

Como configurar el gateway para que transmita con 27 db?

## El gateway no responde la segunda ventana en SF12

Como resumen, vemos que TTN le manda la configuración para la segunda ventan del join request, pero el gateway no lo manda.
