Hello everyone, I need some urgent help. I am using HUAWEI E 1550 Modem for SMS sending. When i am sending (200-250) SMS then it is working just fine, but when i am sending over 500 SMS, an error comes in,
CMS ERROR: Unknown error. -> maybe Sim storage is full? I'll have a look at it. (500) after that kannel tries to again initialize the modem and fails to connect it. some more errors like - "Coundn't connect" or "Wrong or no answer to ATZ" comes in. from the actions it feels like kannel bearerbox tries to rebind the modem again, but it can't. Then i shutdown the bearerbox and try to restart it, still it can't open the the modem in the same USB port now. i disconnected the modem and unplugged it and plugged it in the same port, and still the bearerbox can't connect to the device. I see that AT commands are not going through anymore, just like when i try to bind the modem in wrong USB port. may be plugging the modem in another USB port works, but what i need to know is what can be the possible reason for kannel lossing connection with the modems when more than 500 SMS is sent with throughput = 5 (in case that is important) btw , i am using either Ubuntu server 10 or Ubuntu 10.10. Does anyone faced such problem, can anyone suggest me a solution to this problem? Please help me on this, because i am wasting lot of money trying to test 1000 SMS deliver and i am suffering from this problem for more than 3 months now. Please help. Thank you **
