Testing a GSM module via Mecanique's Serial Communicator - "terminator" issue?

[Ioannis]

Do you have other terminal program to test? My suspicions fall on MCSP serial communicator.

I'll give it a try with PUTTY and HYPERTERMINAL although I don't know how to send control characters with those programs too

But why would it be the problem of my serial program since I need to do the same when I use the PIC?

working with PIC: SEROUT PORTB.4,2,["AT+CMGS=",34,"+4179xxxxxx",34,10,"Hello Roger",26,10,13]

As you can see, here too I need to use a Line Feed instead of a Carriage Return !?

[Ioannis]

You are right.I missed that.

Well, I don't know what is wrong. I remember once, was testing on a SIM900 module with no problems on this. Sure a CR was needed to terminate the command.

For a couple of days I'll be out of town. On my return I will find it and give it a test again.

My module's firmware is Revision:1418B02SIM800L24

...and this the exact module I'm using.

Finally I found the module and time to test the SIM900 board.

Unfortunatelly, while on Power up the module sends what is expected to send, it does not respond to the commands I send.

Tried any combination but failed to reply back...

Sorry but could not help.

Thank you Ioannis.

I'm awaiting a SIM5360EVB and I will try again if the LF or CR makes the difference.
