Hi everyone, Sorry for the late update (had to brush up a bit, my FC skills were a bit rusty ;-) Anyhow I performed a series of test intended to make sure my setup was in working order and to evaluate gsm-fw with Mychaela's new static DSP patch.
Firstly I flashed back leo2moko (gsm-fw.m0) and had the phone connect to a real network; as expected, everything worked fine. I then switched the SIM and started OpenBTS. The phone had no particular problem registering, and both MT and MO calls worked fine. At first I thought something was wrong since fc-shell wouldn't respond to AT commands, but then I realized I should have flashed leo2moko-debug instead of the regular leo2moko. Then I compiled the new gsm-fw and flashed it, then had the phone connect to the test network and place a phone call, using Qt's GUI. The good news is that everything worked fine! The other phone rang, and the audio was of good quality. It seemed however that a noise cancellation feature was present in leo2moko but not here: the noise floor felt higher, as well as the Larsen effect. Hopefully this is something we'll fix with the dynamic DSP patch and/or L1 rewrite. Finally I tried registering gsm-fw on a real network, but it didn't work (registration does not go through); I'm not sure why, a proper investigation will be in order. --DS _______________________________________________ Community mailing list Community@freecalypso.org https://www.freecalypso.org/mailman/listinfo/community
