Chan_Dongle 收SMS亂碼

mcdull

有兩種情況, 有一種直情整死個process, quit左, 連有SMS都唔知.
第二種係出怪碼, SMS forward去email會變成一個垃圾 noname attachment. 會知道收左個SMS但係內容唔知.
有冇解決方法呢?

用既係華為 E180.

留返第時recover 用.

Known issue.

Cannot identify concated messages.  It will generate multiple emails in random orders.
Please let me know on how I can fix it. Thanks.

update:

all " should be replaced by '

if your sim has an unknown number, you can store it with the following command.

dongle cmd dongle0 AT+CPBS=\"ON\"
dongle cmd dongle0 AT+CPBW=1,\"+556191000000\",145

有冇人知道點樣可以將幾個SMS 砌返埋一齊?
分析CMGR係可以知佢係咪split左, 但係 CMGR好似唔係fixed length.

經幾星期發癲, 暫時做到我想佢做既野... asterisk dialplan function 好鬼煩, 尤其係啲 variable.

What is the logic behind in your python to check if all SMS received?
ttmuskie 發表於 2017-9-26 19:51

the python will return 0 if the SMS is single or the last part of the concat message.
and 1 if the SMS is incomplete.. yet.

Originally I intended to use exit code but I cannot capture the return result properly. So I changed it to use the print out.

mcdull

That was the tricky part.  I initially want to decode the pdu just for the concat msg information.  And it was found too complicated and I had to decode much variation of UDH. A lot of tools were available online only. And local library will NOT decode concat message correctly.  So I have to make reference to http://smspdu.benjaminerhart.com/
I have much hesitation to post my sms online as it may contain verification from online banking, so I pulled the javascript (source provided in the site).  With the same reason, I given up to port the javascript to python, so I have to set up a webserver (luckily I already got my own) and use beautifulsoup to capture the output for return.

I will use only the first return character as specified in the dialplan rule.

mcdull

These should work with multiple dongles.  I have 5 installed currently but it is not stable.  I guess the hub cannot power 5 dongles so I removed one and left 4.

mcdull

I am now still facing some issues.
If different message part come together, the python may finish in different time in reserve order and the sms will be displayed and sent in wrong order, and may receive multiple email or incomplete message email.
