Hi
I am using Sim900D with PIC microcontroller (pic18f26k22).
I am sending data using GPRS and HTTP.
Most of the time i get error on the following command
Before issuing this command i am checking if the GPRS is Attach/Detach.If Detach then first Attach GPRS and then issue AT+SAPBR=1,1.
Sometimes i get OK response immediately of the mentioned command and most of the time i get ERROR response and after a very long time i get the OK response.
Is there any way to solve this problem? What should i consider to avoid these problems?
Thanks
