<div dir="ltr"><div class="gmail_default" style="font-family:tahoma,sans-serif;font-size:small;color:rgb(0,0,0)">I'm developing an ESP32/Arduino device to read APRS-IS packets. Using the Client UDP information from <a href="http://www.aprs-is.net">www.aprs-is.net</a>, I connect to <a href="http://first.aprs.net">first.aprs.net</a> on TCP port 10152 and UDP port 8888. I send the logon string to the TCP port and listen on both TCP and UDP. I get a "verified" from TCP and a ping every 20 seconds but never receive anything from UDP. See the results below. </div><div class="gmail_default" style="font-family:tahoma,sans-serif;font-size:small;color:rgb(0,0,0)"><br></div><div class="gmail_default" style="font-family:tahoma,sans-serif;font-size:small;color:rgb(0,0,0)">What am I doing wrong?</div><div class="gmail_default" style="font-family:tahoma,sans-serif;font-size:small;color:rgb(0,0,0)"><br></div><div><div class="gmail_signature"><div dir="ltr"><font face="courier new, monospace" color="#0000ff"><b>73 Karl W4KRL</b></font></div><div dir="ltr"><font face="courier new, monospace" color="#0000ff"><b><div class="gmail_default" style="font-family:tahoma,sans-serif;font-size:small;color:rgb(0,0,0);display:inline"></div><br></b></font></div><div dir="ltr"><div class="gmail_default" style="font-family:tahoma,sans-serif;font-size:small;color:rgb(0,0,0);display:inline">[What I send. <b>What I </b></div><b>receive.</b><div class="gmail_default" style="font-family:tahoma,sans-serif;font-size:small;color:rgb(0,0,0);display:inline"><b> </b>]</div><br></div><div dir="ltr"><br></div><div dir="ltr"><font face="courier new, monospace"><div dir="ltr"><span style="color:rgb(0,0,0)">user W4KRL-3 pass <div class="gmail_default" style="font-family:tahoma,sans-serif;font-size:small;color:rgb(0,0,0);display:inline">****</div> vers D1M-WX1 2.0 UDP 8888 filter r/38.6/-77.5/50</span><br></div><div dir="ltr"><font color="#000000"><b><div class="gmail_default" style="font-family:tahoma,sans-serif;font-size:small;color:rgb(0,0,0);display:inline"></div># javAPRSSrvr 4.2.1b10</b></font></div><div dir="ltr"><font color="#000000"><b># logresp W4KRL-3 verified</b></font></div><div dir="ltr"><br></div><div dir="ltr"><font color="#000000">W4KRL-3>APRS,TCPIP*:W4KRL-9 :Hello from APRS-IS</font></div><div dir="ltr"><font color="#000000">W4KRL-3>APRS,TCPIP*?IGATE?</font></div><div dir="ltr"><font color="#000000"><b><div class="gmail_default" style="font-family:tahoma,sans-serif;font-size:small;color:rgb(0,0,0);display:inline"></div>, server FIRST UDP</b></font></div><div dir="ltr"><b><font color="#000000"><br></font></b></div><div dir="ltr"><div class="gmail_default" style="font-family:tahoma,sans-serif;font-size:small;color:rgb(0,0,0)">[every 20 seconds this appears on the TCP port]</div><br></div><div dir="ltr"><font color="#000000"><b># javAPRSSrvr 4.2.1b10 2018-04-05T22:11:31.803Z FIRST 10152</b></font></div><div style="color:rgb(0,0,255);font-weight:bold"><br></div></font></div></div></div>
