Binary conversion and SMS service

info.ubichip Sat, 10 May 2008 00:54:01 -0700

Hello,

I got some issue with the transmission of sms via kannel and sms service
feature. The original sms is in 7 bit but it is raw data (not ascii one).


When they arrive on kannel, I have the following log in the kannel.log


2008-05-10 09:29:40 [8869] [6] DEBUG: AT2[GSM0]: 1 messages waiting in

I tried to use the %b parameters in the sms service url but without success.

I tried to convert it with bin2hex php code but it  appears like :

3f28a340e90a4040404040404040404040403f405c5c5c27a3f2e90ac7e940a3c7e86a686662

4040404040404040404040

My issue is the format in the http request is not understandable.



How I could get the original raw data as it appears in the kannel log? 
How to tell Kannel to convert in the correct format in the sms service ?

Does someone got some experience on it ?
