dj2ls cc0475d8ad first version ARQv2 2021-12-29 20:42:27 +01:00
dj2ls 3501b4f952 waiting for buffer 
it seems we need to wait a little bit for our modulation data. There are some moments where audio output is stuck a little bit. Maybe python is sometimes faster than the buffer allocation or its a threading problem
 2021-12-26 18:41:43 +01:00
dj2ls 88a0628b53 removed compression, incread callsign set time 
okay, this needs to be tested some more...
 2021-12-26 17:52:05 +01:00

added a directory 003_highsnr_stdio_arq for working on ARQ tests
 2021-12-19 19:45:08 +01:00
dj2ls 5c4667d97d beacon mode 
a first working beacon mode so we can use it for first real hf tests....
 2021-12-06 20:16:14 +01:00
dj2ls 82ddb6a297 modem tests 
updated the modem and codec2 integration. However, this is the old modem. Maybe we need to stay at this point. Lets see how this version performs...hmpf...

DJ2LS 7f45f2e558 fixed timeout for RPT frames closes #77 2021-10-26 17:10:19 +02:00
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...

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

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...

delay between TX and RX 
necessary so we are not sending until other station is in RX mode
