I don't see you PID value, so I cannot comment on what it is, but looking on the internet I see for example this: https://sourceforge.net/p/raspbx/discussion/bugreports/thread/55bc0a67/ where the pid value is 0x39 == 57
Which would be TP-PID 57 "SC-specific; usage based on mutual agreement between the SME and the SC"
https://en.m.wikipedia.org/wiki/GSM_03.40#Protocol_Identifier
SME = Short Messaging Entity SC = Service Center
I suppose allowing anything below 128 would work without any changes.
Try this (compile tested only):
diff --git a/pdu.c b/pdu.c
index 9db8a48..55cbb13 100644

Hi,
Sorry, but I removed the PID data for privacy reasons. If i run it through a PDU decoder I get TP-PID: 39. I will test and report back :) Thanks!
EDIT: I tested it and it works! It doesn't decode the sender alphabetical name but it forwards the sender number instead of halting with an error. This is fully satisfactory for me! My hat off for you and keep up the good work!
Glad to help.
It doesn't decode the sender alphabetical name
That is a different problem. It's probably located somewhere near the parsing of TP-OA
.
I'd still need (parts of) your censored data to try and fix that.
Correction: It's all working great! The sender I used to test an alphabetical sender name started using a phone number for some reason. I tested another sender and its all working like a charm! I'm happy. Again, thank you! 🥇
Hi!
First off I want to thank you for making this patched version of chan_dongle. Its working great and I love it! I've just found one problem with it and this is goes for all of the chan_dongle versions.
I have a E1750 setup to forward all incoming SMS with mail. But it can't handle when the sender uses a alphabetical sender name instead of a number.
[2018-03-10 18:32:02] WARNING[27972]: at_response.c:1232 at_response_cmgr: [dongle0] Error parsing incoming message '+CMGR: 0,,124 **I HAVE REMOVED MY SMS PID_VALUE'** at position 53: Unhandled PID value, only SMS supported
There is similar bugs reported in the other versions of chan_dongle and some patch files are available but I can't get them to work in the version. Any help would be appreciated :)
