Howdy All, I am having a problem where SMS's stop being received after a minute or two of inactivity. Receiving the messages works fine immediately after startup but then nothing.
This is using a Sierra Wireless 875 PCMCIA aircard, using the following config. Log is attached below showing reception of one message, but then nothing even though the keep-alive messages are ACK'ing ok. group = smsc smsc = at modemtype = auto device=/dev/ttyUSB0 my-number = 12063595733 connect-allow-ip = 127.0.0.1 keepalive=60 log-level = 0 I'm using a 60 second keepalive but that doesn't seem to be helping. Any other ideas? 2009-07-19 11:18:52 [10835] [6] DEBUG: AT2[/dev/ttyUSB0]: Found <14> modems in config 2009-07-19 11:18:52 [10835] [6] DEBUG: AT2[/dev/ttyUSB0]: --> AT+CSMS=?^M 2009-07-19 11:18:52 [10835] [6] DEBUG: AT2[/dev/ttyUSB0]: <-- +CSMS: (0-1) 2009-07-19 11:18:52 [10835] [6] DEBUG: AT2[/dev/ttyUSB0]: <-- OK 2009-07-19 11:18:52 [10835] [6] INFO: AT2[/dev/ttyUSB0]: Closing device 2009-07-19 11:18:52 [10835] [6] INFO: AT2[/dev/ttyUSB0]: opening device 2009-07-19 11:18:52 [10835] [6] DEBUG: AT2[/dev/ttyUSB0]: device opened.
