BG5T: SJOTAP trough PDU SMS | Thales IoT Developer Community
March 31, 2015 - 4:02pm, 2916 views
Hi,
I allready managed to make SJOTAP with AT commands, but I can't get it to work with PDU.
I tryed using http://florent.clairambault.fr/smsotap-1-2 which is for TC65. I tryed sending 7bit PDU SMS, which got sent, but nothing happend.
I also folowed instructions here: https://iot-developer.thalesgroup.com/tutorial/otap-pdu-generator , but I can't even send PDU sms. I allways get operation not supported.
Here is what I send and get back:
at<\r><\r><\n>OK<\r><\n>
at+cmgf=0<\r><\r><\n>OK<\r><\n>
AT+CMGS=66<\r><\r><\n>> 0c9183F61542426801000c9183F61542426800F4354f5441505f494d504e470A4e4554555345523A6d6f626974656c0A444e533A382e382e382e380A53544152543A494e5354414c4c0A<26><\r><\n>
+CMS ERROR: operation not supported<\r><\n>
I also noticed that the first PDU SMS is of length 152, which probably can't be sent since in data sheet it says that maximum length of SMS in 8bit can be 140. But seccond one has length 66 and it should be sent.
Here is the image of pdu converter.

Hello Jure,
If the first generator is working I'd stay with if for now.
Some networks may not support OTAP messages.
In the sjotap command there's a parameter <Ignore_Sms_PID> - set it to on and try to send SMS with other PID then.
Please also check if your sms storage is not full.
Best regards,

Hi Bartłomiej,
<Ignore_Sms_PID> was off. So I played a little bit more with the first program that was made for TC65 so that it generated SMS's so that all were shorter then 140, PID and calss were set to 0, coding was 8bit and it worked.
So if anyone else will have similiar problem you can download program that is in the first post and try.
Thank you and best regards,
Jure
