Thanks, good suggestions both Valkyrie and Nevyn. I didn't know netmf could do dynamically loaded libraries, nor had I seen that boot loader thread. I'll dig in and post the results.

The various platforms are the major issue. I have to work something out for firmware/software updates, but that will be mfdeploy based. As for user config - http was the answer (but cabled, not wifi - so default ip sorted that out)

Colin, did you determine if it was possible to do a firmware/software update over the network (cabled or otherwise)? That is a requirement for a project I'm working on here, and I'm not yet sure how to approach that. I guess ideally I'd like something like a router firmware update procedure via HTTP, but I don't know what is involved to jockey an image into flash memory. Maybe via SD somehow?

Thanks Valkyrie-MT, good suggestion to try running in the emulator. I managed to get the Netduino to send multicast packets on Friday, I just need to verify by writing a PC client to ensure that they show up if I join the group correctly. I believe most of the socket option calls I was trying are for joining a group in NETMF which would be extremely useful for my application, but not required. I'll let you know what I find.

I have the exact same issue using v4.2 firmware.

This is the code i tried to use, taken from another site / forum (im very much still learning)

...
// DHCP
NI.EnableDhcp();
//NI.ReleaseDhcpLease();
NI.RenewDhcpLease();
...

I've found that for whatever reason calling ReleaseDhcpLease()/RenewDhcpLease() doesn't actually seem to do so - the lease never gets renewed. If I just enable DHCP it usually sorts itself out after that. It would be nice if there was a callback on DHCP events instead of having to poll for a valid address, but this is a start.

This code is a derivative of the I2CBus class Pavel Bansky developed. This will help you easily manage multiple I2C devices on a single bus. My I2CBus implements the Singleton pattern. Please note this is done this way because you can only have one instance of I2CDevice and it can sometimes be hard to manage multiple I2C devices.

Hi phantomtypist, what is the license for your I2CBus class?

Thanks and regards,
