To use multiple networks with i.MX6.

[satoshishimoda]

Hi community,

I have a basic question about i.MX6 network.

Actually, our partner want to use 2 networks simultaneously.

In this case, I think they can do it if they use i.MX6 ENET and Wi-Fi module which has USB (or SDIO or PCIe) I/F.

Is my understanding correct?

Yes. You can use both Ethernet and Wi-Fi simultaneously.
For example you can route one network to another.
Or you can simply access both networks from your device
but not forward packets from one network to another.

Hi Victor Linnik,

Thank you for your reply.

I think each network can get difference IP addresses in this case, is this right?

Yes. You need to use different IP addresses and different networks on these interfaces.
I mean (just as an example) you can use 192.168.1.1 and 192.168.2.1 but not 192.168.1.1 and 192.168.1.2.

Hi Victor Linnik,

To make sure, I have one more question.

Can both networks use completely different network IP addresses?
(e.g. 128.100.1.1 & 132.200.1.1)

In Android, we understand Android API don't support connecting to specified network in this case.

So I want to confirm what is OK and what is NG.

192.168.1.x and 192.168.2.x I meant as an example of different /24 networks.
Of course you can use 128.100.1.1 and 132.200.1.1 IP addresses as well.

Hi Victor,

Would you give me advice?

Hi Victor,

Is Android API no problem to use different networks?

If Android BSP (jb4.2, jb4.3, kk4.4) modification is needed to use different network at the same time, would you let me know it?

Or can we use the different networks without any modification?
