    Hi,

    we're looking for rock solid combination of RTOS, TCP Stack and DHCP (and other) client.

    What for ?
    We need stable DHCP client, so module gets safely IP number all the time. We need stable TCP stack so module can exchange messages with the cloud storage.
    And probably we also need RTOS...


    Why ?

    Because our experiences were not so good in the past, we're seeking for recomendation on rock solid development combo - we're currently evaluating Ti connected Launchpad....

    Previous experiences:
    Ti seems to have problem with demo app (or better said driver), cause it dies after day or two... we also hear about some unstable DHCP clients also. Therefore we would kindly ask
    if you can point out your favourite combo...

    Thanks in advance,

    best regards,

    Kiro.

    Are you using the CC3200 Simplelink launchpad? I've just bought a couple of them for a potential product as well, arriving late this week if the expected delivery date is to be believed.

    Otherwise I've used the lwIP stack with a Cortex M3, however without an OS. I found it to be a little difficult at times because of the memory constraints of the M3, but otherwise not too bad at all. I had a memory hungry application, and then also the stack on a 64K ram device. If memory isn't a huge issue, its a good route to investigate.
