# WizFi 210 AT+NAUTO UDP server mode?

## Question

Asked by vstelegin on 2014-02-06 in Wireless.

Hi, how can I set Auto Connection to UDP server mode?
TCP mode works:
[ul]
AT+NAUTO=1,1,5000
[OK]
[/ul]

UDP mode don’t work:
[ul]
AT+NAUTO=1,0,5055
[ERROR: INVALID INPUT]
[/ul]

Non-auto UDP server mode works.

WizFi210
1.1.0.5(W)

Hello vstelegin

FW 1.1.0.x support TCP-Server, TCP-Client and UDP-Client mode.

But, FW 1.2.0.x support TCP-Server, TCP-Client, UDP-Server and UDP-Client mode.

If you want to use UDP-Server using <at+nauto=1,0,5055>, you need to use FW 1.2.0.x.
