Encoding and SMS

[JGranborg]

I´m working with SMS in pika warp using asterisk.
No problem sending SMS´s, but I have som trouble regarding the danish letters ÆØÅ and æøå.
What Encoding do I have to use to get these characters.
I'm using the GsmSendSMS Action.

Yes, the GSM module uses IRA encoding by default instead of unicode. This would likely explain the behaviour you are seeing. To change this I would recommend the following commands at the Asterisk CLI (assuming port 1):

gsm send at 1 AT+CSCS="HEX"
gsm send at 1 AT+CSMP=1,167,0,8

After this configuration, your SMS messages can be tried again - hopefully with the proper characters.

To share my reference, in the following webpage under the topic of 'Sending an Unicode SMS message" there is a rough explanation of the procedure. http://www.smssolutions.net/tutorials/gsm/sendsmsat/

Hope this helps.
