P252DMR Connects Then Disconnects from HBLink #47

Open K2IE opened 4 years ago

In trying to use P252DMR with HBlink3, P252DMR will successfully connect to HBlink, but only remain connected for about 15 seconds and then drop the connection. HBlink reports that P252DMR is dropping the connection:

In communication with the HBlink folks, the default config is that HBlink sends a udp ping every 5 seconds to the client. If the client missed three responses, the connection is dropped. It was suggested that I raise the number of retries. When I raised it to 5, it worked a little better (5x5=25 seconds), but there are still frequent drops.

Also I noticed that CPU is pegged at 100% of 1 core (RPi 3B) running P252DMR so there may be some condition going on that is inhibiting response time and overall performance.
