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
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.
