Hi all!
In order to avoid the most common problems, I propose exporting something like a feature bitmask on the L1CTL, i.e.
* L1CTL user code (layer23) can send a L1CTL_GET_FEAT_REQ request * laye1 in the phone sends a L1CTL_GET_FEAT_RESP with all the bits set to 1 for the features it supports * L1CTL user code (layer23) can then check if all the features it needs are supported by the L1. IF not, it can simply abort or print a warning to the user.
We can simply extend the size of the bitmask over time if we need more bits.
Obvious bits I would consider are:
- is this firmware compiled with TX support? - does this firmware contain a SIM reader driver? - does this firmware support BURST_IND?
Maybe we could also include a static header containing a compile timestamp or the git date/revision that the firmware was built, as well as a name of the board.
Now I know, nice idea, who will implement it? I currently have othe priorities, but if somebody lurking on this list is looking for a relatively simple way to contribute back to the project (without knowing anything about GSM!) this might be something useful you could do.
Thanks in advance, Harald
