Hi,
For the SIM reader, how about using SAP (SIM Access Profile) ?
Originally it's a bluetooth profile
http://www.bluetooth.com/Specification%20Documents/SAP_SPEC_V11.pdf.
It's not as powerful as PC/SC, because SIM in mind instead of SmartCard,
but it makes it much simpler and lighter (could be integrated in futur
ROM). The specs are small.
There should then be a SAP server for the card reader, and osmocom would
have a SAP client.
This architecture would provide the possibility the access the SIM card
also from a client on a computer, but also have a SIM server on the
computer for osmocom (using standard PC/SC card reader).
Greetings,
Kevin

Hi!
I think we corrently have the following TODO list.
GSM Layer 1:
* implement transmit power control for transmit
* implement SDCCH/8 on TS1-7 (Sylvain)
* implement frequency hopping
* proper split between synchronous and asynchronous part of L1 (Harald)
* TCH/F support (Dieter, after L3 RR/MM/CC is working)
* A5/1 and A5/2 encryption support
GSM Layer 2:
* implement a real layer2 that deserves the name (full LAPDm implementation)
* properly encapsulate / abstract the L1 "MPH" primitives so L3 doesnt
call L1 directly anymore
GSM Layer 3:
* test most of the code that Andreas has written (depends on L1 / L2)
Misc:
* SIM card driver + ISO7816 FS API
* Battery charger driver
* UI framework
* minimal journalling flash file system
* decide which RTOS kernel we want to use (Harald)
* fully support a working firmware build for the openmoko gta01/gta02 GSM modem
using calypso romloader
For people who don't feel like they can take any of this work, there is some
other work, regarding the mid-term port to our next target platform:
* implement host utility for the medaitek MT622x romloader serial protocol
* try to get a minimal hello world codebase to run on the MT622x
* write hardware drivers for UART, PMU, I2C, SPI, ... of the MT622x
Regards,
Harald.
