Hi,
I’m trying to follow client mode example of TCPIP exchange from AT document. I get OK response for all commands until KTCPSND command, once I send this one I never get CONNECT from modem and after that modem does not respond to anything (data terminated with KPATTERN, +++, other commands) until I reset it.
Any ideas what is going ion here ?
thanks
Branislav
my modem is HL8548-G, KGSN returns SV:04
