Hi Raj,

Sorry I am replying this late. But have been working furiously in the meantime : Bought a WIZ810MJ module; interfaced it to a Silab kit SPI interface ; coded the basic requirements and I am quite happy to say that yesterday the module started responding to Ping requests. Not a award winning achievement - but to learn, understand and do it on your own is the fun part.

Now I want to upgrade to the next level - UDP - and send data to the Laptop once every 100mS. The data is simply this :

"AIN0 Channel xxx.xx Bar
AIN1 Channel yyy.yy Nm"

Just to make sure I am on right track :
- Write the following to the relevant registers on 810MJ module:

* INIT the module.
* Open Socket_0 and assign 8K memory to TX and RX.
* Set the mode to UDP.
* Assign "5000" as the Socket_0 port.
* Open the socket and verify if its in UDP mode.
* Write the IP number of my laptop.
* Write the port number to use on my laptop ( how to find this port number ?)
* Write the data to transmitt memory with proper offset etc.
* Write the command to "Send"

- Would the above be adequate ? Do I need to close the socket after every transmission or do I close when I decide to power down ?

Thanks

Raghu
