Thanks Shyam,

One more thing to ask... It's about bulk sms facility, If I want to send a same query to all remote unit, at present I am sending one by one sms to all intended mobile numbers ( and it takes hell lot of time!!!

). But I know that some modem has bulk sms facility, my understanding about bulk sms is sending same sms to multiple units more efficiently.. (i.e with lower microcontroller over head and taking less time to send them all...) is it true?... Is it advisable to use that facility??

Thanks.

hi Divyang..

yes most of us trying to make SMS server kinda devices are facing this problem.....

if u r going for bulk SMS in that case (q24Plus) modules will be in a state of wait!!!

but in OPenAT u might be running a lot of other timers!! so may be sometimes the bulk sms gets canceled...

better create different threads for different recepients and then rum them concurrently...

the above statement also keeps in consideration that u are firing AT commands rather than the OpenAT apis.
if using OpenAT Apis there will not be much of a problem cause u have a tiny OS (firmware) to back on!!

Hi Shyam,

This time I get confused.. not getting you properly.. Your one statement -"OPenAT u might be running a lot of other timers!! so may be sometimes the bulk sms gets canceled" - reveals that OPenAT is not reliable and the last statement of your post contradict it by saying - "if using OpenAT Apis there will not be much of a problem"… Hope you understand my problem…should I go for OPenAT or firing AT commands by separate application without using OPenAT..
