So. What? Gonna be linux based, (Of course.) What will we need? I'm gonna guess this'll be based on the OpenEmbedded toolkit. A Bootstrap base? I can't see us needing a GUI on a phone emulator. . . So we'll need Stacks, and an interface to the iMX.

Things that are going to need alot of thinking:

The data protocol for the USB connection to the iMX. . . We have the Serial link for AT control, but 3G data, GPRS data, and videophone data will all need to go on the USB bus. . . What else? MMS's, Access to the data on the SIM card, (Own number, SIM-phonebook: Will need a tie in to our AddressBook in the PDA OS. . .)

The software that controls the RPU and DSP. . . Needed functions?

It's going to have to be able to wake the iMX so that the iMX can handle CallerID, send any required information to the twin displays and to bluetooth (And whatever else you guys route it to wink.gif Caller log?)

Genii (Geniuses?) give me your opinion.

GPRS is not out of date, thats like saying that computers are out of date 2 weeks after you buy them. they are still good for what the do at the very least

the gprs module will become a bit of a hot topic in the futre i belive, the DSP thing was kind of a joke (i wasn't sure if many would get it) for gsm the modulation is fairly simple and i am not sure how much DSP'ing we will have to do (need to read the phone chip docs)

ethire way short term i would like to buy a stack as a binary to keep costs down and make sure we have somthing that works and not "will work in +12 months

the stack we are refering to is low level and runs on its own processor, it presents a serial port to the host os which will obey the AT command set or simmilar, that way it should work with all oss modem stuff. it is a low level OS just like the qualcomm units, IT IS IN NO WAY A LOW LEVEL KERNEL DRIVER. after all how can it be when it runs on its own seperat hardware and communicates over a serial line
