The connection to the bluetooth device and all the messages and responses to and from the mobile phone work fine. So the bluetooth part is done. Now the GSM module will need to have the data from the SIM of the mobile phone to use it for connectiong to the GSM network. Since I use a device from Siemens (AC45) it already has the multiplexing (GSM 07.10) integrated meaning that I can send an AT-command (at+cmux=0) and it will switch to multiplexing mode and work as required. It will know how to handle data packets coming in from the serial port to divide them into each channel and how to pack the data with the apppropriate header from each multiplexing channel to be sent back over the single serial port. The missing part is in my software. It will need to wrap and unwrap the messages to and from the GSM modem in the form it is defined in the specification for this multiplexing. There is solution of a final year project of a student in Finnland available, but it seems to possible have a few bugs. (http://users.tkk.fi/~tkarvone/). Compiling is fine and the load of user space serial port module at runtime is ok too. To my understanding a controlling application is the second part of this project, which will open the port and enable the multiplexing of the GSM device and then wait for data coming into or out of the "virtual" ports, wrapping or unwrapping the data packets. Or am I wrong and have to replace the application with my blueZ-SAP-application? Has anyone used this multiplexing implementation successfully or does anyone know of a different implementation of the multiplexing as opensource to use with linux?
