I am problem in my project with Telit Module to activate the GPRS from MCU UART.
I know the EasyGPRS AT Commands to Activate GPRS and send UDP Data. The strange issue is ... when I an sending the AT Command manually by typing from PC Hyper-Terminal then all works. Module can send UDP Data to Server. But when I am sending exact same AT Commands from MCU UART then Module reply ERROR against AT#SGACT=1,1,"","". But other AT Command reply is OK.
Below are my Command which I tried with Module Response (with Echo ON):
+CME ERROR: activation failed
+CME ERROR: operation not supported
I tried the regular GPRS AT Command as well. Then same ERROR comes with AT#GPRS=1 Command.
Note: The problem only happens when I can sending the Command from MCU. Exact same Command working fine when sending from PC Hyper-Terminal ...
Anyone can advise whats the issue?
Thanks in advance.
