Hi, I am trying to use the push registry with a SMS for awakening a midlet on a phone. I am using NowSMS with a Cingular Sony T637 for sending the SMS to a Sprint Sanyo MM8300. For some reason, the SMS goes directly to the inbox of the Sanyo and the Push Registry is not invoked. I followed the example (User Header -060504xxxxyyyy) in http://support.nowsms.com/discus/messages/1/2008.ht ml but it's not working. Another issue is that if I use a Data Coding Scheme other than 0, the SMS is not received at all. Bryce and others, can you pls help me out? | |||

Hi Pradeep, This is an issue of sending from GSM to CDMA. Basically, when you send a message from a GSM modem to a CDMA recipient (or even between 2 GSM operators in the USA because they use the same interconnect), the SMS interconnect that connects the operators together does not like binary messages. Of course, there is also no concept of User Data Header (UDH) in CDMA. I know with BREW they use text messages that start with //BREW. I'm not sure how things work for application directed messages for Java midlets in the CDMA world. I wonder if they use text based WDP (derived from Nokia Smart Messaging, where the text messages start with //SCKL) ... as access to send binary SMS messages to a CDMA network is challenging if you are not the mobile operator yourself. I'd suggest trying to send a pure text message, with the following format: //SCKLxxxxyyyy Your Text Here Unfortunately, I suspect this won't work. The Java WMA specifications indicate that binary WDP is used (Section 6.5 of the WDP specification). Unfortunately, I can tell you from experience that getting a binary connection that would allow you to send this type of message is next to impossible. (Although you might want to inquire with the SMS provider SimpleWire ... as someone recently told me that they think SimpleWire supports binary messaging to the US CDMA operators. If they do, you could still use the UDH when submitting to NowSMS, but configure the SMPP connection in NowSMS to use WDP Adaptation ... we would then use an intermediate format for transmission over SMPP, and an SMPP server that understands this would translate to the appropriate format for CDMA or GSM.) If you find anything else out, I'd love to hear about it. Unfortunately, getting an SMSC connection that supports binary messaging to CDMA operators is extremely rare. -bn | |||
