Why both? Because my understanding was that you got data from a HP2551 to CumulusMX via a GW1100 gateway.
But I am getting problems. If I select the station type as GW1000 and set it up with IP and MAC addresses every now and again I get "Invalid Response" and the data stops. Attached is full debugging log, with Debug, Data and FTP logging enabled. You will see that around 17:23:45 the log shows an "Invalid Response", but it manages to reconnect around 17:24:17 and starts re-reading data.
Then at 17:33:50 it gets another "Invalid Response" but this time it goes fully "tits up" and this continues until 20:19:05 when I noticed it and pulled the USB connection and then plugged it back in and it immediately reconnected!!
I must add here much KUDOS to betaljuices's MXDiags Interrogator which makes sorting through a long MXDiag log really easy http://www.beteljuice.co.uk/DEMOS/newmx/diag.html
Now if I stop using the GW1100 and just use HTTP to the HP2551 it works perfectly without a hiccup.
So am I doing this wrong or do I have a faulty GW1100 or am I being a prat
