Bryan Biedenkapp 0f237c7435 update copyright dates;
3 years ago
Bryan Biedenkapp 2ae52143ab implement remaining code required for permit-tg and embedded STC support [untested, considered experimental]; implement proper DMR T3 grant fixes to handle slot granting properly;
3 years ago
Bryan Biedenkapp a102956e1d implement start of support for non-authoritative CC (this is a situation where a FNE STC is configured); implement RCON to return the list of configured voice channels from a CC; continue implementation of permit-tg (still not done);
3 years ago
Bryan Biedenkapp ea84df2228 remove grant rsp/req from normal network path (this is being rearchitected); add new plumbing for determining if a DVM is authoritative for repeating traffic and auto-granting;
3 years ago
Bryan Biedenkapp d89c90118d convert DMR to follow the factory code pattern for CSBKs;
3 years ago
Bryan Biedenkapp 727a3eb155 convert more behaviors from C-like to C++11 (replace NULL with nullptr mostly); make some pointer safe changes to DMR;
3 years ago
Bryan Biedenkapp 73a2f03be4 implement CSBK and RCCH verbosity control support (similar to P25 TSBK verbosity control); allow CSBK and RCCH verbosity to be set from RCON; enhance RCON to properly omit digital protocols not compiled in; enhance RCON commands for debug, verbosity and data dumping to report currently set settings;
3 years ago
Bryan Biedenkapp a476d0c7eb set DMR registration requirement on whether or not the CC is dedicated;
3 years ago
Bryan Biedenkapp a10c64b950 update config file for new DMR parameters; add affiliation support to DMR; cleanup implementation of CSBK generation in ControlSignaling; implement rudimentary SU registration (doesn't quite work yet);
3 years ago
Bryan Biedenkapp 24b6cca301 make TSCC Aloha NRand_Wait and Backoff configurable; set TSCC Aloha NRand_Wait to a resaonable value so as to not DDoS the inbound TSCC slot; mark CSBKO_RAND as "handled";
3 years ago
Bryan Biedenkapp 9ca505ff5c [EXPERIMENTAL] implement support for basic NXDN (requires -DENABLE_NXDN_SUPPORT and the v3 nxdn branch firmware!); implement support for handling v3 firmware;
4 years ago
Bryan Biedenkapp 9a4906ecac implement marking builds with the Git hash automatically; fix issue with DMR CC not terminating when dvmhost is shutting down; fix issue with DMR CC incorrectly transmitting frames; implement DVM specific opcodes that transmit the Git hash over the air;
4 years ago
Bryan Biedenkapp 6fd1fe6b76 bump copyright dates; add copyright banner at startup;
4 years ago
Bryan Biedenkapp 91b932c1ea revert modem buffer sizes to pre-reorganization size; implement support to dump the modem status "dumpModemStatus"; refactor LookupTable to use C++ instead of bad C file loading (possible fix for a bad heap corruption problem); implement CC data interval timer for DMR CC;
4 years ago
Bryan Biedenkapp 328bd1024d code reorganization;
4 years ago
Bryan Biedenkapp 66e6787f33 clarify buffer overflow message; refactor DMR and P25 code for clarity regarding how the queue buffer for the digital protocols works; refactor P25 control channel processing code into the p25::Control class clock function proper; refactor the naming of the network write functions (the naming was confusing); refactor how queue sizes are calculated, instead of using raw bytes an input, use the number of desired frames as input from config.yml; adjust the internal intermediate modem buffer sizes; implement a short delay between P25 CC packets of ~5ms, this is to give the processor time to handle packets inbetween generating CC data frames; refactor PDU handling, we no longer instantly transmit the registration response, instead following spec transmit it ~1 second after the request; implement and use the modem write immediate support for P25 PDUs and some P25 TSDUs; in the case of P25 voice call late entry, ensure we perform the appropriate queue clear and state resets; refactor and consolidate how the end of frame data is written after a voice call on P25;
4 years ago
Bryan Biedenkapp 43f8f6e8ae implement support for a silence threshold in DMR (this will help null highly degraded audio to prevent horrifying ear destroying screeching); some minor code cleanup (mostly removing magic numbers!);
4 years ago
Bryan Biedenkapp 8b5a7ae7ec add experimental support for DMR TIII (note this will not accept registrations or grant requests);
4 years ago
Bryan Biedenkapp 595f6f4dd9 fix issue that caused an assertion crash when resetting the modem; store the DataHeader data during DMR traffic for future use;
5 years ago

5 years ago
Bryan Biedenkapp a0ef0aaf63 code cleanup;
5 years ago
Bryan Biedenkapp f095065451 split DMR CSBK handling into its own packet handler class; cleanup DMR data and voice packet handlers (processing for certain data packets wasn't exactly right); move some common variables into the main Slot class;
5 years ago
Bryan Biedenkapp 6d1644b99e file cleanups; implement BCAST_ANNC_ANN_WD_TSCC; add support for channel identity lookups in DMR; fix a couple of issues with BCAST packet formatting;
