What are you trying to achieve? Please describe it in detail.
Getting data from the TTN Network into the Cumulocity Cloud
Do you get any error messages? Please provide a full error message screenshot and log file.
The connection is fine. I am following the tutorial here:
the Lora Devices (a Dragino LDS02 Door Sensor) is created. And the message ist the following:
Ttn uplink request
{ “devId”: “eui-a84041c13184f93f”, “payloadBase64Encoded”: “DFoBAAA2AAAKAA==”, “port”: 10, “appId”: “my-temperatur11”, “devEui”: “A84041C13184F93F”, “timestamp”: “2022-09-29T11:39:38.588602142Z” }
How can i build a LORA Device Protocol now?
The Base64 Payload of that Device is “DFoBAAA2AAAKAA==” in my example.
it means in HEX: “0c5a0100003600000a00” correct?
and the TTN Payload Formatter is the following:
function decodeUplink(input) {
var port = input.fPort;
var bytes = input.bytes;
var value=(bytes[0]<<8 | bytes[1])&0x3FFF;
var bat=value/1000;//Battery,units:V
var door_open_status=bytes[0]&0x80?1:0;//1:open,0:close
var water_leak_status=bytes[0]&0x40?1:0;
var mod=bytes[2];
var alarm=bytes[9]&0x01;
var data = {};
switch (input.fPort) {
case 10:
if(mod==1){
var open_times=bytes[3]<<16 | bytes[4]<<8 | bytes[5];
var open_duration=bytes[6]<<16 | bytes[7]<<8 | bytes[8];//units:min
data.BAT_V=bat,
data.MOD=mod,
data.DOOR_OPEN_STATUS=door_open_status,
data.DOOR_OPEN_TIMES=open_times,
data.LAST_DOOR_OPEN_DURATION=open_duration,
data.ALARM=alarm
}
else if(mod==2)
{
var leak_times=bytes[3]<<16 | bytes[4]<<8 | bytes[5];
var leak_duration=bytes[6]<<16 | bytes[7]<<8 | bytes[8];//units:min
data.BAT_V=bat,
data.MOD=mod,
data.WATER_LEAK_STATUS=water_leak_status,
data.WATER_LEAK_TIMES=leak_times,
data.LAST_WATER_LEAK_DURATION=leak_duration
}
else if(mod==3)
{
data.BAT_V=bat,
data.MOD=mod,
data.DOOR_OPEN_STATUS=door_open_status,
data.WATER_LEAK_STATUS=water_leak_status,
data.ALARM=alarm
}
else{
data.BAT_V=bat,
data.MOD=mod
}
return {
data: data,
}
default:
return {
errors: ["unknown FPort"]
}
}
}
and the result should be something like that:
{
"ALARM": 0,
"BAT_V": 3.162,
"DOOR_OPEN_STATUS": 0,
"DOOR_OPEN_TIMES": 54,
"LAST_DOOR_OPEN_DURATION": 10,
"MOD": 1
}
please help to make a Cumulocity Device Protocol for the LDS02
Thank you
