Trying to run on OpenWRT routers #9

Ive managed to cross-compile this for OpenWRT routers in the hope of using one as a simple fm streaming server, but upon connecting the terminal is spamming the following message over and over:

"dropping input buffer: 262144 B"

All that is produced from the receiving device is intermittent static every few seconds.

I'm guessing its because these routers are low-powered devices, but I have been using rtl_tcp on them just fine. Is there anything that can be done to improve performance on these budget devices?

Please observe the CPU load of you device while demodulating. Most likely the CPU of routes are ways too slow.

@thecosmicslug Have you tried the rtl_fm utility and, if yes, does it work?

Hi. do you have the steps to cross-compile on OpenWRT? I have a new SBC with 6-core CPU, so CPU load might not be the bottleneck.
