debugging of gsm /cdma

Give hardware connection details for how to write on flash of (Q24series)cdma/gsmchips.
is there any possibility to write to flash via microcontroller? please give harware details regarding this.

Have you actually looked at the Datasheets for the Q24 Series?

You program them with the Wavecom AT+WDWL command.

Yes, you can send AT commands with a microcontroller!

But why would you want to?

The whole point of Open-AT is that it allows you to use the module as a microcontroller - thus obviating the need for an external microcontroller!

There are situations where you might want to use an external microcontroller. It all really depends on your needs, and for 99.99% of your needs, you’re not likely to need it.
