Hey Bryce, I'm hoping you can help me. We bought a Multitech CDMA US wireless modem (MTCBA-C-U) because we want to implement SMS sending and receiving in the CDMA environment with our in-house application. I installed the modem properly with Multitech drivers (I did a query modem on the Modem Diagnostics under Control Panel and it said "Success"). I activated it under Sprint USA (went through the AT commands activation in Hyperterminal and I got to the end without any problems). Multitech modems come with a software to test the modem called mobilePhone Tools. I am able to send and receive text messages using this interface. However, when I add the modem to the NOWSMS Gateway, it gives me a "Modem does not support SMS AT+CSMS=128 Error". I am puzzled because a minute ago, I was able to send and receive SMS. I read through this forum and got the idea to go to the Hyperterminal and issue some AT commands. I did the AT+CSMS=0 and it gave me an error. I did the AT+CMGF=0 and it gave me error as well. I called multitech and they said that the AT+CSMS=0 and AT+CMGF=0 are GSM commands and doesn't work on CDMA modems. We did the AT+CMGS="xxxxxxxxxx" (xxxxxxxxxx is a cellphone number) and were able to send a text message out to a cell phone from the Hyperterminal. I have NOWSMS 2006. Is there a way to ignore the checks you perform when adding a modem to NOWSMS? Seems like the Gateway is issuing an AT command that doesn't apply to CDMA modems (AT+CSMS=0). Maybe a patch to get rid of this check because clearly, I can send SMS and the modem does support SMS. I also have a GSM modem connected to this machine and it works fine with NOWSMS. I am aware of CDMA problems with binary SMS but in this case, I only want to use regular text SMS so that shouldn’t be an issue. I added CommandPreInit1=AT+CFUN=1 in my SMSGW.ini file under the MODEM tab but then I realized I haven’t even added the modem so it is under the GSM MODEM tab right now. That still didn’t work. In NOWSMS, I tried connecting directly to the COM4. Didn’t work either. I connected using the modem name and that didn’t work. This is a new modem with a new Sprint plan so I am not aware of any PIN I need to provide. As far as I know, I didn’t set any PIN. I issued AT+CSQ and verified that there is signal. I also issued AT+CREG and verified that it is registered on the network. Any ideas? Bryce? Anyone? I would really appreciate any help on this. Thank you. Mark | |||

Hi Mark, I'm confused, because I have an "AT command" reference for the Multitech CDMA modem which listed this command as supported. But I'm looking at a 2006 version of this manual, and things have changed. They support an "AT+CSMS?" command ... but no commands to set a value with this command. And by not supporting any variants of AT+CMGF, I don't know how they expect software to determine that the modem only supports text mode. But I guess we can make some assumptions if our regular tests fail. I've uploaded a NowSMS update to http://www.nowsms.com/download/markcdma.zip. Give that update a try, and let me know if that works. -bn | |||

Hey Bryce, Thanks for the quick reply. I downloaded the patch you sent and I was able to add my CDMA Multitech modem. However, (without 2way config settings) when I send an SMS to the CDMA modem, I do not see it in the SMS-IN directory or in the SMSIN-yyyymmdd.LOG file. I have another modem connected to NOWSMS (a GSM modem) and when I send to that, I see the file in SMS-IN directory and in the SMSIN log. When I try to send a message out using the GSM modem (using the URL /?PhoneNumber=14082984902&Sender=16083984098&Text=thisisatest552pm) I receive it on my cell phone but when I replace the Sender part of the URL with the number of the CDMA modem, I receive the message but the number it comes from is the GSM modem. So even though I was able to add the CDMA modem to NOWSMS, I am not able to send or receive SMS. Any ideas? Has anyone ever been successful at configuring a CDMA modem with NOWSMS? From what I heard in your reply, setting of AT+CSMS to 0 and AT+CMGF were once supported but not anymore. Is this what you meant? I'm wondering if I should call Multitech again and ask them for an upgrade or downgrade of the firmware that comes with it. Should I ask for the list of AT commands that their firmware was based on so we can see exactly what Multitech supports or doesn't support? Thanks again for your help. Mark | |||

Hi Mark, You can't override the sender when sending a message using a GSM modem, and I would assume the same to be true with a CDMA modem. Regarding receiving messages ... firmware versions ... etc ... I'm trying to track down information, but it's generally easier for me to deal with the "here and now". I think I've got some pretty detailed specs, and I see 2 compatibility issues with regard to receiving messages. We've updated the URL from before ... http://www.nowsms.com/download/markcdma.zip ... to address these 2 issues. Whether or not you are able to successfully receive SMS messages with this update, I'd like to see an SMSDEBUG.LOG, which will give me a better idea of the modem issues. -bn | |||
