I am using the Pinnacle 100 from Laird that uses the HL7800. I am being told by Laird that the 7800 does not support SMS, but could if the driver was written. From what I have read here the 7800 does support SMS, so I’m not sure if the driver now handles that, or if I need to do something more. Is there any information to show me where to start here to write that?
you can just send AT command (e.g. AT+CMGS) through the AT command port to send SMS.
So I have been trying these AT commands. and using the +CMGR, and +CMGLI can see I have a message (see below), but I do not see how to view the actual text message. Is there another conversion I need to use?

That online tool is great, and that confirms that I am getting the intended messages and content. Thank you for that! Is the PDU decoding key readily available? I’m just trying to figure out how I would decode message on the Pinnacle 100 to display the text on an LCD display connected to it. After looking through that, I may have figured out a way to convert this.
What do you mean by PDU decoding key
I need the Pinnacle 100 to recognize specific text messages sent and act on those in the code appropriately and display the received text message on an attached LCD Display. The text has to be in a readable format, in this case, TEST8.
Perhaps I misunderstood, but when I receive the SMS on the Pinnacle 100, I would have to convert it to PDU to get the readable text. That is what I meant by a “key”

Can you show what exactly you receive the sms the Pinnacle 100?
I wonder if you can read this SMS by text mode:
AT+CMGF=1
AT+CMGR=4
This is what I get back for TEST:
