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.
