RTLTCP: timeout and "ll" from rtl_tcp

docker run -p8100:8100 ghcr.io/jvde-github/ais-catcher:latest -N 8100 -t rtltcp my.server.ip 1234

[ERROR] RTLTCP: timeout.

from rtl_tcp on my sever I get

ll+, now 492
ll+, now 493
ll+, now 494
ll+, now 495
ll+, now 496
ll+, now 497
ll+, now 498
ll+, now 499
ll+, now 500
ll+, now 501
ll+, now 502

Seems like ais-catcher is requesting too much data from the server - although there's about 150 megabits of bandwidth between them. Things like FM reception work fine.

Yes, I experience the same, even on a local network and using other utililities. Have you tried running at a lower sample rate, like -s 288k ?

[voltagex]

Still no good with -s 288k, however this seems to work:

docker run -p8100:8100 ghcr.io/jvde-github/ais-catcher:latest -N 8100 -t rtltcp my.ip 1234 -gt TIMEOUT 60

I get

TCP Server: start thread at port 8100
HTML Server running at port 8100
TCP (server.ip:1234): connected.
RTLTCP: setting parameters

and from the server

Use the device argument 'rtl_tcp=0.0.0.0:1234' in OsmoSDR (gr-osmosdr) source
to receive samples in GRC and control rtl_tcp parameters (frequency, gain, ...).

Thanks. Let me do some checking as well….

Ok, thanks. In the old implementation timeout was set at 2 by default, this got lost when moving to the new set up (was zero). Thanks for flagging and sharing observations. This is fixed now and should be in the Docker in 30 minutes.

Thanks again!
