Yeah thanks very much for those links. I finally went with http://django-websocket-redis.readthedocs.io/en/latest/heartbeats.html and although the javascript needed adapting I managed to get it to work and now a warning popup appears to alert the operator. All done!
@moose4621 WOW man you are rocking this rice paddy :-) well done
standbuy
standby
@denman0000_gitlab Just found a library for writing kml files in arduino. Yay.
@moose4621 wow ok re KML .. you did mention the geolocation stuff too .. very cool
@moose4621 you're on a roll
@denman0000_gitlab if (heartbeat_interval === null) {
missed_heartbeats = 0;
heartbeat_interval = setInterval(function() {
try {
missed_heartbeats++;
if (missed_heartbeats >= 3){
alert("Signal to seeder lost! Check WIFI connection and reload page to continue");
throw new Error("Too many missed heartbeats.");
}
missed_heartbeats = 0;
heartbeat_interval = setInterval(function() {
try {
missed_heartbeats++;
if (missed_heartbeats >= 3){
alert("Signal to seeder lost! Check WIFI connection and reload page to continue");
throw new Error("Too many missed heartbeats.");
}
connection.send(heartbeat_msg);
} catch(e) {
clearInterval(heartbeat_interval);
heartbeat_interval = null;
console.warn("Closing connection. Reason: " + e.message);
connection.close();
}
}, 5000);
}
@denman0000_gitlab Thats weird
@denman0000_gitlab This is the important bit. alert("Signal to seeder lost! Check WIFI connection and reload page to continue");
@devyte Well thanks and you ?
@antonedvard Try Serial.println(answer,15);
@antonedvard The 15 is the number of decimal places to print.
and too little time
oh, and also an experimental integration of w5100/w5500 ethernet shields into lwip as additional interfaces
:D I feel that way myself about some of what the fellow developers have done. That bearssl alternative to axtls was a huge piece of code, the migration to lwip2 was mindboggling, as is the integration into lwip of the ethernet shields, and don't get me started on the available heap improvements and stack placement voodoo
@ashthespy I have it working using my own bastardized method but still want/need to understand typecasting. 'int setpointVariable100 = setpointVariable / 10;
int setpointVariable10 = setpointVariable - (setpointVariable100 10);
int targetGroundSpeed100 = targetGroundSpeed / 10;
int targetGroundSpeed10 = targetGroundSpeed - (targetGroundSpeed100 10);
uint8_t payload[4] = {0, 0, 0, 0};
payload[0] = setpointVariable100;
payload[1] = setpointVariable10;
payload[2] = targetGroundSpeed100;
payload[3] = targetGroundSpeed10;
webSocket.broadcastBIN(payload, sizeof(payload));'
int setpointVariable10 = setpointVariable - (setpointVariable100 10);
int targetGroundSpeed100 = targetGroundSpeed / 10;
int targetGroundSpeed10 = targetGroundSpeed - (targetGroundSpeed100 10);
uint8_t payload[4] = {0, 0, 0, 0};
payload[0] = setpointVariable100;
payload[1] = setpointVariable10;
payload[2] = targetGroundSpeed100;
payload[3] = targetGroundSpeed10;

stupid markup
