#107099 - 2ms - Eh???
Responding to: ???'s previous message

Here I am using GPRS MODEM, so I need lot of periodic data requests (every 2 ms AT Command data request and data response).

I don't see that this has anything specifically to do with GPRS.

As far as I know, there is nothing in GPRS that forces you to send an AT commend every 2ms !

I worked on a project with GPRS on (effectively) a standard 8052 UART, plus two other UARTs, plus 1-Wire, and a few other bits without trouble. It used Keil's example interrupt-driven serial scheme almost straight from the tin!

If that GPRS had been doing an AT command every 2ms, I think there'd have been trouble...!
