I followed the installation steps indicated in OsmocomGMR. There was an example for FACCH3 channel to generate the G matrix. I modified the code for TCH3 (shown below) but the output results does not seems correct. I would really appreciate it if you can tell me what I am doing wrong in the code below. /* GMR-1 G/g matrix geneation forTCH3 */ /* (C) 2011 by Sylvain Munaut * All Rights Reserved * * This program is free software; you can redistribute it and/or modify * it under the terms of the GNU Affero General Public License as published by * the Free Software Foundation; either version 3 of the License, or * (at your option) any later version. * * This program is distributed in the hope that it will be useful, * but WITHOUT ANY WARRANTY; without even the implied warranty of * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

I guess it was mostly an oversight when the date was originally announced, and not a lack of interest? ;) All details about the event are available at the related wiki page at: https://osmocom.org/projects/osmo-dev-con/wiki/OsmoDevCon2019 Please enter your name at https://osmocom.org/projects/osmo-dev-con/wiki/OsmoDevCon2019#Requested in case you would like to attend. Registering early allows proper planning. Thanks! Looking forward to meeting old and new Osmocom developers in April 2019.
