CR310 network interface priority

AHann Feb 11, 2019 02:06 AM

Hi all,

I've been at this all day with no luck. So hopefully somebody out there can provide some guidance.

I'm using a serial modem with the CR310. The eth port is used to interface with network devices that don't need internet access.

Everything works fine with AT configuration over serial, followed by PPPOpen.

When I attempted to TCPOpen() the process either fails or the logger crashes and re-compiles.

I've tried, IPRoute(server IP, PPP) but TCPOpen still hangs or fails to connect.

Is there any way to set the interface priority so that PPP is ranked higher than eth?

For clarification the exact same routines etc work flawlessly with a CR300. So it must be routing related, but I can't find anything in the documentation around this.

Attempted with OS7.05, 8.00, and 8.01 all fail.

There is a third parameter for IPRoute() that was introducted in OS 08.01 called ExlusiveOption. Setting it to 1 will force the connection your logger is needing to make.
