SIM900 - Send SMS over 160 characters using Gammu

Question

I am using raspberry Pi 3 for sending SMS using SIM900A. I configured Gammu to send SMS via SIM900A and it worked fine. But I was able to send only 156 characters(Max). I need to send more than 200 characters.

Command I used : " echo 'MESSAGE' | sudo gammu sendsms TEXT +91XXXXXXXXXX"

Is there any way to do that? I am open for both AT commands and Gammu way.

Thanks in advance...

P.S : I would prefer TEXT format than PDU

Answer 1

This works for me.

Please try this.

echo 'MESSAGE' | sudo gammu sendsms TEXT +91XXXXXXXXXX" -len 400

Internally gammu sends more than one message if it is greater than 156 characters, but that is transparent to you. You only send a message with that command of up to 400 characters, and the phone receives 1 SMS only.
