Hi, I downloaded the Now SMS Gateway v2006.03.09 and tried to send SMS messages but the recipient didn’t receive those SMS messages. I am using a BlackBerry 7100t handheld as the GSM modem. The modem is connected and working well, since I can connect into Internet through the modem. The operator is Rogers in Canada. I can send SMS from this handheld to another one. Then, I installed the gateway, added the “standard modem” in the “SMSC” page, set the phone number and also set the SMS access property to be “GSM”, and then tested the SMSC connection. The test result showed “Modem successfully tested”; Then, I changed to the “Web” page to make sure that the “Enable menu driven web interface” is checked on; Next, I went to the “Service page”, checked on the “Run as service”, and then opened the browser to http://127.0.0.1:8800//. As the result, I can see the “Send Text Message” page. I put the local phone number and the text, and then submitted, but I didn’t receive the SMS on the destination cell phone. Then I put a full phone number with “+1” and tried again, but still got nothing. The attached files are the log files under the gateway directory. Could you please take a look this case and let me know what the problem is? Thanks!

Hi Luke, Unfortunately, it looks like the GSM modem capability built into the Blackberry model that you have is deficient. The responses that I see in the SMSDEBUG.LOG show that the modem does not properly understand the AT commands for sending an SMS. It is possible that maybe the modem only properly understands text mode SMS only, whereas NowSMS defaults to PDU mode (which supports both text and binary). To try configuring NowSMS to talk to the modem for text mode SMS only, manually edit SMSGW.INI, and under the [Modem - Standard Modem] section, add ModemTextMode=Yes Let's see if that makes any difference. I've got access to a Blackberry 8700 ... and it's modem interface supports data connectivity only (test for support for the SMS commands fails). -bn | ||||

Hi, Bryce, Thanks for your reply. I tried to add "ModemTextMode=Yes" to the ini file and tested again, but still didn't work. In the BlackBerry modem properties, for the "Extra initialization commands", the value is set to be (AT+CGDCONT=1,"IP","internet.com"). After executing the "Query Modem" command, it seems the "AT" commands can be executed successfully. The log is recorded in the attached file "ModemLog_Standard Modem.txt"; Then, I tested the modem in NowSMS again, and opened the service, and then tried to send a Text Message. But still, the recipient didn't receive the message. I put the modem log for the full process in the attached file "ModemLog_Standard Modem_2.txt". Also, there are log files from the NowSMS directory. Hope you can find something from them. Maybe the BlackBerry cannot be used as SMS modem? Thanks! Luke

Hi Luke, It looks like the modem does not support the AT commands for sending SMS. Or if it does, it is not following the spec. The "AT+CMGS" command is always returning "OK" ... but this command should be a two-step process. The modem should return ">" which indicates a command continuation response ... or "ERROR". It's puzzling that the modem would respond "OK" ... because it hasn't actually done anything. My suspicion is that they didn't actually implement these commands in the Blackberry ... that they just implemented the GPRS related commands so that the device could be used as a data modem for internet access. I've been looking to see if I could locate any technical information on the AT commands implemented by various Blackberry models, but I haven't found anything. I can only confirm that on an 8700, NowSMS reports that the modem doesn't support SMS, because the initialisation test to determine if the modem supports AT commands for SMS fails. Since the 7100 was released before the 8700, and was one of the first Blackberry's to support IP modem capability, maybe they returned OK responses to more commands thinking that it might be necessary to do so in order to get more software to recognise it as a data modem ... But it doesn't look like they support SMS via this interface. -bn | ||||
