io.ReadFull error when executing rtlamr after running successfully for a while #321
Description
Hello rtlamr community,
I am running rtl_tcp as a service on Ubuntu 22.04.2 LTS and executing rtlamr as a cronjob for 15 meters to read the values
once a day. I am encountering this error after running for a while. In the latest instance it failed on day 24. I stopped rtl_tcp
service and started in manually as shown in the trace below, however it didn't help, as shown in the trace of rtlamr
The previous time this happened some time ago - I rebooted the server and it helped, however the issue reappeared.
I am wondering if there's a way to address this without rebooting.
This time, instead of rebooting the server, I removed and reinserted Nooelec RTL-SDR USB and it fixed the issue.
It seems that the problem is between rtl_tcp server and Nooelec USB. I wonder if anyone has ideas on how to
fix this, or a way restart software service(s) instead of manual USB removal
Thank you in advance for your help!
