Hi all,

Today I connected a SMS modem to HM. The Modem is a Siemens ES75 (MC75i) and every time HM tries to send an SMS, wther manual by using the test function or from an action profile, there is an error in the AT commands.

Com port open .. Ok
GSM modem initialization .. Ok
Error: Cannot send message to MYPHONENUMBER. GSM modem error. ERROR was returned on AT command: AT+CMGS=152>0001000A81601877252300F1A0CDF27C1E3E974166F9BB0D42BEE7F4E6DB9DA6BFE52014FA3DA783C6E8B0FB5C2683E6F430BD3E4F2914D4F29C0E028140201D28999C8268305A441EA6A7DF20142F09F5A514CD321DFD26EB40C9E414042FCBCD6F793BEC1E9741285E12EA4B29A6F430BD3E07817420E79B0EA297E7F43259410CD3CB201008A403C572AFF79AFE92C16431104CA69BCD74
Com port close .. Ok
GSM modem deinitialization .. Ok

What could cause this?

Hard to say, such devices do not provide good diagnostic data.
HostMonitor 12.98?
Have you tried Text mode?
Correct service center number specified?

HostMonitor 12.98? Yes
Have you tried Text mode? Yes
Correct service center number specified? Yes

But I found that if I enter the AT commands directly in the terminal of the modem they return an error so I think the AT commando needs to be formatted different somehow.

Don't ask me what I did but it works with all the default setting.
