DJ2LS	df38ee01ba	gui & tnc improvements ... displaying now frequency offset and frequency in heard stations. Decreased size of receiving audio buffer, which seems to optimize RX	2021-10-24 14:44:55 +02:00
DJ2LS	5bfd745747	data_handler ready for chat messages ... data handler is now ready for chat messages. I updated the data frame with an additional information -datatype- so we can determine if we received a file or a message. Each datatype will be saved into an own buffer. The gui has been updated as well, so we can forward data directly to a future chat module...	2021-10-17 16:59:15 +02:00
DJ2LS	655d333af2	freq offset handling #81 ... first attempt just with pings. Station A sends a ping to Station B. Station B is detecting RX offset, adds it to the ping acknowledge frame and sends it back to Station A. Station A will then adjust the frequency	2021-10-13 19:39:46 +02:00
DJ2LS	82f307cf1f	introduced info toasts #80 ... first attempt with info toasts which seems to work fine. Next step will be adding more detailed information to them like a progress bar and specific closing	2021-10-07 21:04:23 +02:00

DJ2LS	1bbd2692db	improved ARQ closes #66, closes #74 ... improved transfer rate calculation and cleanup. improved speed of ARQ by sending early frame ACK instead of burst ACK and then FRAME ACK	2021-10-05 19:59:32 +02:00
DJ2LS	0b115bd00c	smaller changes ... added DATAC0 to send data via bad path. Fixed stop transmission for receiving. Fixed a possible error in main.py	2021-10-02 11:46:29 +02:00
DJ2LS	8b08cc6e6b	stop transmission ... first attempt with stopping a transmission after the processing the current burst. Logging is a little bit ugly at this point, because it looks like a frame got lost. However, the transmission stops. CLI output is only visible for people interested in debugging...	2021-10-02 11:29:08 +02:00
