UDPBind problem

[Bester]

Hello guys,

please excuse my noobness.

I`m trying to communicate with arduino using UDP and i have no problem sending data, but if i try to use UDPBind and UDPRecv to receive data i`m getting error 10049 from UDPBind. 

If anybody could help me out that would be great.

Thanks

Global $udp
Global $sent
Global $recv
Global $new

UDPStartup()

$udp = UDPOpen("10.3.1.94", 8888)
If @error Then ConsoleWrite("udp open error: " & @error & @CRLF)

$sent = UDPSend($udp, "off")
If @error Then ConsoleWrite("udp send error: " & @error & @CRLF)

ConsoleWrite($sent & " bytes sent" & @CRLF)

UDPCloseSocket($udp)


$new = UDPBind("10.3.1.94", 8888)
If @error Then ConsoleWrite("udp bind error: " & @error & @CRLF)

$recv = UDPRecv($new, 1000)

UDPCloseSocket($new)

UDPShutdown()

10049

Cannot assign requested address.

The requested address is not valid in its context. This normally results from an attempt to bind to an address that is not valid for the local computer. This can also result from connect, sendto, WSAConnect, WSAJoinLeaf, or WSASendTo when the remote address or port is not valid for a remote computer (for example, address or port 0).

Probably you've set a wrong address with UDPBind

[Bester]

Thanks for the reply,

and yes i found that, but somehow that didn`t helped me, since i think my address is valid, because i can send data to that address.

[JohnOne]

I can sent data to any IP address in the world, but they are not IP addresses of my local computer.

[Bester]

Oh, so the ip address in the UDPBind is suppose to be my and not the device i`m trying to listen to? Wasn`t clear in the help file so i thought it`s gonna be same as for UDPOpen. Well thank you for the help, but now i`m getting error -1 from UDPRecv (invalid socketarray) :/

[j0kky]

Which IP have you setted with UDPBind?

[JohnOne]

Oh, so the ip address in the UDPBind is suppose to be my and not the device i`m trying to listen to? Wasn`t clear in the help file so i thought it`s gonna be same as for UDPOpen. Well thank you for the help, but now i`m getting error -1 from UDPRecv (invalid socketarray) :/

Yes, I suppose the help file could mention the valid address must be local.

[JohnOne]

You should probably use the Macro.

@IPAddress1

[Bester]

So my ip address is 10.3.1.91 and arduino is 10.3.1.94, yet still getting error -1 

[JohnOne]

@IPAddress1 gives you 10.3.1.91?

[j0kky]

I've a question: how do you run Autoit executables in Arduino?

[Bester]

yes, my ip is 10.3.1.91, my home subnet is 10.3.1.0/24, also i`m not running autoit on arduino, i`m trying to send data to arduino via UDP using autoit, and i can already do that, i just can`t receive data from arduino

I'm not familiar with arduino, but have you looked into the possibility of there being firewall issue?

[Bester]

Yes i have, autoit has all rights to access the network, i think i just messed up something in my code, since i`m getting 'invalid socketarray' error from UDPRecv.
Also thank you guys so much for helping me out here. Much appreciated.

Try to create the server modifying this paramenter couple (IP-Port) of UDPBind:

@IPAddress1 - 8888

@IPAddress1 - 65432

127.0.0.1 - 8888

127.0.0.1 - 65432

And report the various errors for each couple.

I'm facing a similar issue. I want to bind to UDP multicast address 239.255.250.250 on port 9131.

I get an error 10049 with `UDPBind("239.255.250.250", 9131)`.

I do not see any option to specify that it is a multicast address. I'm stuck here.
