Hi,

I’ve a problem with adl\_adwrite.

To write a word like Hello i use the function like this:

```auto
CodiResposta= adl_adWrite(1,15,*dades);
```

Where dades is a pointer to “hello” word.

When i execute this i found this problem:

```auto
ADL_RET_ERR_UNKNOWN_HDL
```

First of all i do a format to flash and then subscribe to funcionts.

Thanks in advanced!

Best regards.

I’ve found a problem with subscribe.

On manual says that returned value of Handle is: “The cell positive or null handle on success;” in my case returns a NULL, but when i use this null in the adl\_adwrite the program give an errorand break.

Anyone knows why i can’t use thhis null or why gives me a null the adl\_adsubscrive funcion?

Thanks a lot! 🙂😕
