[quote userid="79078" url="~/f/nordic-q-a/46992/send-text-by-ble/185730"] I'm using BLECharacteristic library[/quote]

I have no idea what that is. It's not a Nordic thing, is it?

Have you contacted the author for support?

As noted above, Nordic's UART Service (NUS) can do what you require.

This code works with data of numerical type (values between 0 and 255)

uint8_t SoporteBLE::enviaTiempoEspera()
{
    uint8_t tiempoEspera;
    if(Bluefruit.connected()){
        if (TiempoEspera.read8()) {
            tiempoEspera = (uint8_t) TiempoEspera.read8();
            delay(250);
        }else{
            tiempoEspera = 0;
        }
    }
    return tiempoEspera;
}

But i need to send data of text type, String or char*, I'm using BLECharacteristic library, I tried with read64 function, but whe I try to send text, the module doesn't receive any data, if during configuratio of charcteristics I modifiy this value to a higher value, the module receives unreadable ASCII characters

Sentido.setFixedLen(1);

Please post the code legibly, then I'll look at it.

Also, please give more detail on, "don´t work"

What were you expecting to happen?
What is actually happening?
What testing / debugging / investigation have you done to find the problem?
