Thank you for working on WioLoRaWANFieldTester.
I am a newbie in LoRaWAN, so pardon my ignorance.
I purchased a WioLoRaWANFieldTester field tester with battery from seeed.
i am only interested in TTN, not Helium.
After reinstalling firmware and setting GPS to 9600bds, I could register on my TTN Gateway and GPS worked. After long hours of testing I cannot upload any information.
I followed the instructions on the wiki, unfortunately, I don't understand how to set-up TTN payload formatters. I followed the instructions on the wiki without adding any formatters, unfortunately it replies "impossible to decode data". So I need to decode data ...
I found this webhook code and used it:
function Decoder(bytes, port) {
var decoded = {};
if ( port != 1 ) return decoded;
var lonSign = (bytes[0]>>7) & 0x01 ? -1 : 1;
var latSign = (bytes[0]>>6) & 0x01 ? -1 : 1;
var encLat = ((bytes[0] & 0x3f)<<17)+
(bytes[1]<<9)+
(bytes[2]<<1)+
(bytes[3]>>7);
var encLon = ((bytes[3] & 0x7f)<<16)+
(bytes[4]<<8)+
bytes[5];
var hdop = bytes[8]/10;
var sats = bytes[9];
const maxHdop = 2;
const minSats = 5;
if ((hdop < maxHdop) && (sats >= minSats)) {
// Send only acceptable quality of position to mappers
decoded.latitude = latSign * (encLat * 108 + 53) / 10000000;
decoded.longitude = lonSign * (encLon * 215 + 107) / 10000000;
decoded.altitude = ((bytes[6]<<8)+bytes[7])-1000;
decoded.accuracy = (hdop*5+5)/10
decoded.hdop = hdop;
decoded.sats = sats;
} else {
decoded.error = "Need more GPS precision (hdop must be <"+maxHdop+
" & sats must be >= "+minSats+") current hdop: "+hdop+" & sats:"+sats;
}
return decoded;
}
Also I wonder whether it is possible to use an experimental project in TTN Mapper for TTN. Can I integrate directly wih TTN Mapper and not disk91. With the above script "decoded_payload": {}, so data never reaches TNT Mapper.
Please advise:
1) Which TTN payload is needed ? Is the above webhook correct ?
2) Can I upload directly to TNT mapper or should I use your backend?
