Wireless Joint

That's what I'm talking about. They turn it off, but the trigger to turn it back on is just to reinitialize the LTE session. If you could do that without dropping packets, it'd prevent the CA from ever going off (with proper scripting).

What we need is a method of reinitializing the LTE session with no packet loss. Disabling and reenabling the interface takes too long. If you have it set for B2/B66, and it flips the anchor bands between the two, it will reinitialize the session without any packet loss. I've seen it countless times....

When I try the AT+QMBNCFG="List" in an EP06A or EM12G, I get

"output: "

So it's blank.

Anyone else seen this? EC25AF outputs as expected.

I've confirmed this behavior on EP06A, Mikrotik LTE6, EM7455, and EM12G. After a set amount of time, the link goes "stale". AT&T turns off the CA for that link. Anything that resets that link re-establishes CA immediately. No need to "download a large file"...CA doesn't work ...

Same problem with an SINR of 15~18dB. It's not a signal thing. I think it's AT&T plus a firmware thing. I also don't have a problem on T-Mobile. Same issue, it stops working, and it comes back if I fiddle with the band locking or if I to a USB power reset or a full reboot, but then goes out a fe...
