I see that there are two UART ports in your project, Debug and UART. Can you please tell if you are viewing both the UART COM PORTs in Hyper terminal? Can you try increasing the size of TX buffer of UART.
Thank you for your kind reply hima and exetremly sorry for delayed reply because i was in sick leave
actually am using Two UART COM PORTS
one UART PORT (UART named in the topdesign) for the gsm module inorder to send the AT Commands and and another UART(Debug) which is used to see the what are commands are being entered into the second UART and also to view the return reponse for the respective AT commands from the Second UART
Actually am viewing only one UART on the hyperterminal which is named as Debug on the TOPDDESIGN
the actual problem in PSOC 3
if the enter the AT commnds manually i am getting the proper response on the both UART and Debug
but when the send the AT commands uisng PutString fucntion it is showing immediately aborted or some misplaced characters on each time could you please help me because am really blocked and not able to move forward without able to find where the problem is coming from
could you please tell me what do you meant TX bufffer size increment because i am using only RX buffer in my software no where i have declared or modified anything about the TX buffer
eagerly looking forward for your reply
What I meant is to increase the RX buffer size. Sorry for the typo from my end.
Hello thank you so much for your kind reply even i have increased the size of the RX buffer already before posting this question but still it is showing some extra unwanted characters please suggest me some other possibl solution so that i can move forward
Thanks for your kind suggestion i am able to found the solution for my problem it is just because of infinite loop and the execution are too much in a quick time because of that it showed some unwanted characteres
