Hi all,

I was trying to use my new DA16200 Wifi Shield with Ardunio UNO. Looks like I wont be able to use the library [https://github.com/ArmDeveloperEcosyste … or-Arduino](https://github.com/ArmDeveloperEcosystem/DA16200-WiFi-Library-for-Arduino) for it. Is there any library already created by someone ?.

Also I tired to use the AT commands via serial to connect to wifi router. I am able to use commands like creating a TCP socket and receive messages but I am unable to send messages. I am getting

```auto
ERROR:-1

```

Also I am not able to use the commands like

```auto
AT+NWHTC=http://54.147.68.244/get,get

```

I tried the following example in the document to get the serial open on ardunio. Any help is appreciated

Upon further checking I found out that some few commands are available when I type "? "or “help”. How do I get to see and use full AT+ commands ?
