New connector, products not in the list
Hi everyone,
for the RAK2171, a very common GPS locator sensor, I don't see the connector. A similar issue is for all the RAK products.
Is something under develop? Otherwise I need to create its own payload parser, but that it would take a while to do it; I found this parser for the trackit Rak2171, I hope it works:
function Decoder(bytes, port) {
var decoded = {};
// adjust time zone, here Asia/Manila = +8H
var my_time_zone = (8 * 60 * 60);
decoded.num = bytes[1];
decoded.app_id = (bytes[2] << 24) | (bytes[3] << 16) | (bytes[4] << 8) | bytes[5];
decoded.dev_id = (bytes[6] << 24) | (bytes[7] << 16) | (bytes[8] << 8) | bytes[9];
switch (bytes[0]) {
case 0xCA: // No Location fix
decoded.acc = 0;
decoded.fix = 0;
decoded.batt = bytes[10];
decoded.time = ((bytes[11] << 24) | (bytes[12] << 16) | (bytes[13] << 8) | bytes[14]);
// adjust time zone
decoded.time = decoded.time + my_time_zone;
var dev_date = new Date(decoded.time * 1000);
decoded.time_stamp = dev_date.getHours() + ":" + dev_date.getMinutes();
decoded.date_stamp = dev_date.getDate() + "." + (dev_date.getMonth() + 1) + "." + dev_date.getFullYear();
decoded.stat = bytes[15] & 0x03;
decoded.gps = bytes[15] & 0x0C;
break;
case 0xCB: // Location fix
decoded.fix = 1;
decoded.batt = bytes[20];
decoded.time = ((bytes[21] << 24) | (bytes[22] << 16) | (bytes[23] << 8) | bytes[24]);
// adjust time zone
decoded.time = decoded.time + my_time_zone;
var dev_date = new Date(decoded.time * 1000);
decoded.time_stamp = dev_date.getHours() + ":" + dev_date.getMinutes();
decoded.date_stamp = dev_date.getDate() + "." + (dev_date.getMonth() + 1) + "." + dev_date.getFullYear();
decoded.stat = bytes[25] & 0x03;
decoded.gps = bytes[25] & 0x0C;
decoded.lng = (((bytes[10] << 24) | (bytes[11] << 16) | (bytes[12] << 8) | bytes[13]) * 0.000001).toFixed(6);
decoded.lat = (((bytes[14] << 24) | (bytes[15] << 16) | (bytes[16] << 8) | bytes[17]) * 0.000001).toFixed(6);
decoded.acc = bytes[18];
decoded.gps_start = bytes[19];
break;
case 0xCC: // SOS
decoded.sos = 1;
decoded.lng = (((bytes[10] << 24) | (bytes[11] << 16) | (bytes[12] << 8) | bytes[13]) * 0.000001).toFixed(6);
decoded.lat = (((bytes[14] << 24) | (bytes[15] << 16) | (bytes[16] << 8) | bytes[17]) * 0.000001).toFixed(6);
if (bytes.length > 18) {
var i;
for (i = 18; i < 28; i++) {
decoded.name += bytes[i].toString();
}
for (i = 28; i < 40; i++) {
decoded.country += bytes[i].toString();
}
for (i = 39; i < 50; i++) {
decoded.phone += bytes[i].toString();
}
}
break;
case 0xCD:
decoded.sos = 0;
break;
case 0xCE:
decoded.alarm = 0x01;
decoded.alarm_lvl = bytes[10];
break;
}
return decoded;
}
Thank you,
Paolo
