Part Number: CC3100
Other Parts Discussed in Thread: TM4C129ENCPDT, CC3200,

Hi Everyone,

I am working to implement where i need to switch between network connection , for example when my device (TM4C129ENCPDT ) needs internet connection either from wifi or from ethernet, when wifi connection lost it should switch to ethernet connection, or if ethernet connection lost it should connect to wifi network , how can i implement this feature and what are the http.networkstack should be ( Http.networkStack = Http.SimpleLink; /Http.networkStack = Http.NDK;) ?, where can i find refference ? can these both co exist ? ,

Thanks in advance

regards,

Chiranth

We have never used this but theoretically it can be done.

Though CC3200 may also work, I would recommend using CC3220/CC323x for the network bypass mode (i.e. interface that enables the connection to the AP and supporting Ethernet interface afterward - see section 6.5.4 in www.ti.com/.../swru455)

I think this mode was available in CC3200 but it was not verified.

I believe the NDK supports having 2 network interfaces (with the bypass mode enabling the Wi-Fi to interfaces as an Ethernet device).

As you understand there are not many resources that we can provides to help you started and our ability to support this is limited.

HI kobi ,

i went through that document , is that Network Bypass mode can be implemented on CC3100 chip as well ? because we have to implement on deployed devices as we cant change the wifi chip for deployed devices?

theoretically yes (the socket types should be available), but it was never verified on cc3100 and we will be limited in supporting issues on this product.
