Decoders for Chirpstack v4

Current decode payloads for Chirpstack only work for v3, changes in Chirpstack v4 cause examples to fail due to new func signature changes referenced here. For example a quick fix to LDS02 was to prepend the following:

function decodeUplink(input) {
    var sensor_data = Decode(input.fPort, input.bytes);
    return {data: sensor_data};
  }

// Existing Chirpstack v3 decoder example below...
function Decode(fPort, bytes) {
    ...

LHT65N Chirpstack 4.0 decoder.txt variable typo

Hello,
in the decoder "LHT65N/LHT65N Chirpstack 4.0 decoder.txt" for LHT65N the variable port at le line 100
if((port==3)....
should be if((fPort==3)....

Thanks
Jacques

GPS values when not establish connections with GPS providers

Valid values for Longitude is +/- 180, Latitude range is +/-90.
The payload decoder delivers a "0" for Longitude and Latitude , when there is no connection with GPS providers.
But: this is a valid location in the near of Libreville (Africa). The decoder has to deliver a value out of range, e.g. 255 for Longitude and 128 for Latitude.
So can detected that the GPS-values are invalid data.

DS03a-LB RSSI not supported in Chirpstack v4?

Cannot decode any RSSI, cannot find rssi decode entry in file.

LHT65N Datalog bug

https://github.com/dragino/dragino-end-node-decoder/blob/main/LHT65N/LHT65N-chirpstack%20decoder.txt

string 76:
var poll_message_status=((bytes[6]>>7)&0x01);

should be shift by 6 not 7 like that:
var poll_message_status=((bytes[6]>>6)&0x01);

Same error in other LHT65N decoders (ttn, etc)

LHT65N offline data bug (PollNoneAck mode)

For decode offline data (PollNoneAck mode), needs extend decoder like that:

LHT65N External Sensor Data not Uploading (Chirpstack v4)

LHT65N Internal (Built-in) Temperature/Humidity Readings Upload to Datacake and post properly, but no data is detected when using the external probe (Sensor reading EXT-TempC_SHT).

External Temp Probe readings do post to

Could you please check the Dragino End Decoder for Chirpstack V4 to ensure that the External Sensor settings is passed to the decoder?

LDDS75 decoder incorrectly saved to LDDS45 decoder folder

I think the LDDS75 decoder has been saved to the LDDS45 decoder folder.

CPL01 Decoder doesn't work properly

However it can be fixed by just changing all instances of "port" to "fPort" or vice versa

PS LB Decoder water depth wrong calculation

On PS LB water level sensor, this formula causes all depts to be a 0 cm.
decode.Water_deep_cm= parseFloat(((decode.IDC_intput_mA-4.0)*(bytes[3]*100/16)).toFixed(3));
bytes[3] alwasy return as 0 and. I think during water level calculation this formula can be static value.

//5000 mm is the max distance the sensor can measure
maxSensorRange = 5000;
//Density of water is 1 ton/m3 (1000 kg/m3)
liquidDensity = 0.997;
//The "Current to Voltage" module can only move between 4mA to 20mA which gives it a resolution of 16mA.
maxSensorResolution = 16;
depthChangeStep = ((maxSensorRange / liquidDensity) / maxSensorResolution);
// dept can be measured as mm sensivity
decode.Water_deep_mm= parseFloat(((decode.IDC_intput_mA-4.0)*(depthChangeStep)).toFixed(3));

What is the expected value for bytes[3] ? Am I rigth to calculate like this _

The LTC2 decoder doesn't work correctly

The ltc2 decoding does not work correctly with ltc2-ht when they pass 300, TTN show -200, is this normal?
I am waiting for an answer.
