Thanks. I set up an account with AllThingsTalk Maker. I even created a pinboard which was connected to TTN (allegedly) but nothing ever showed up. So that’s another fail. I don’t think this stuff has a future…

Graphing data
Hi @Qmick, I think that “free” does not have a future. Either you have to pay with your own time and skills and make stuff or you have to pay with money for other people’s time and skills.
This topic has offered you both options - pay with time or pay with money - it seems that you reject both of those. There’s an old Chinese saying; “a peasant will stand for a long time on a hillside with his mouth open before a roast duck flies in”.

TTN Console stopped showing downlinks for TTIG
Sorry for my silence, I’m quite busy right now but I’m still checking this topic from time to time.
Unfortunately no, I only have my own devices that I didn’t manage to make work properly for downlinks before the strange behaviour happened, so I cannot be sure that the fact my device is not receiving messages is coming from the gateway and not from a bad configuration of my device.

RN2483 - Trigger mac state call
Thanks for the advice, Kersing
It is not that I am afraid of an unstable node. I just would like to see the sequence of the states.

Lgt-92 & Cayenne not working
The raw Cayenne makes no sense, for example the first few bytes 02 C6 46 E4 would decode as
- 0x02: channel 2
- 0xC6: datatype 0xC6=198 -> is not defined
- data = 0x46 0xE4 ? (we can’t know the length of undefined data types)
How did the other payload fields get decoded?
I think you’re not using Cayenne!

Calculating the time between two packets (TTN + Node-RED)
Thanks a lot for the valuable information and my apologizes for using photos instead of codes ,i’d a simple programming question , would you show me how i can extract the meta data of the gateway (ID,rssi, snr…etc) in separate variables rather than objects so they can be printed the same way as the frequency and data-rate , i try your example :
var gateways = msg.metadata.gateways;
return {
mylocation: msg.metadata.location,
// Combine RSSI and SNR of all gateways into two arrays:
rssi: gateways.map(gw => gw.rssi),
snr: gateways.map(gw => gw.snr),
// ...or: get an array with an object for each gateway:
gateways: gateways.map(gw => {
return {
GW_ID: gw.gtw_id,
location: {
lat: gw.latitude,
lng: gw.longitude,
alt: gw.altitude
},
// rssi: gw.rssi,
// snr: gw.snr
}
})
};
i need that because it seems that the .csv node doesn’t accept to store objects , but it stores variables (i was able to store the output of the interval time node but for a reason i don’t know i can’t store the gateway data )
I get only a .csv file for the time-interval, I just want to link the (delay information with the GateWay information).

Applied could be that the power is on, but is more likely to be as you put it on - as in “I applied a bandage” - I put it on …

Replacing gateway
My Mikrotik gateway stopped to work and I sent it back as a warranty case. When I get it back it will be probably not the same gateway. Could I reuse my application and devices setup with new gateway or should I make all over again?

Replacing gateway
Gateways have no unique role in LoRaWAN at all, the protocol is entirely a contract between the nodes and the servers, gateways just pass traffic with no idea what it even means.
Additionally in the community network ownership of gateways is irrelevant - your nodes could be using someone else’s nearby gateway, other peoples nodes could be using yours. In fact nodes use all of the gateways in range of their current air settings all of the time; the network combines the reports from the gateways into a single copy of a given message, and tries to identify the closest gateway (via signal quality) on the infrequent occasions where a downlink needs to be sent in reply.
(That said, there are tiny demo-scale networks where the network server software runs on the processor inside the gateway; but those aren’t TTN and so aren’t on topic here)

SF and required SNR not matching
Hello!
I am using a LoRa Stick (LoStik) from Ronoth which has an RN2483 Module (https://ronoth.com/products/lostik)
I did some performance measures with ADR and I am bit confused about SNR and the Spreading Factor.
I found a table in an old Semtech Document which shows, which SNR is required for a specific Data Rate
Unfortunately, my measures does not match that.
My device is sending most of the time with SF12, even if the SNR is about -5dB. Shouldn´t ADR adapt the DR in that case?
I am about 3.5 km away from the gateway.
I would be happy if someone could help me understand ADR fully.
Thanks
Goodrun

Lostik+RaspberryPi+LairdGW Setup issues
OK - I spoke too soon. I can successfully join.
I can see the data on my local gateway. (I see the join request)
I can see the join request on TTN in the Gateway and in the Application itself.
{
"time": "2020-07-06T17:13:18.022676599Z",
"frequency": 904.3,
"modulation": "LORA",
"data_rate": "SF10BW125",
"coding_rate": "4/5",
"gateways": [

"timestamp": 2942281724,
"time": "",
"channel": 2,
"rssi": -16,
"snr": 6.25
}
]
}
But I never see the payload show up:
Joining... got: b'ok\r\n'
Joining... got: b''
Joining... got: b'accepted\r\n'
b'mac tx uncnf 1 48656c6c6f20576f726c6421'
Executing String: mac tx uncnf 1 48656c6c6f20576f726c6421
Executing: mac tx uncnf 1 48656c6c6f20576f726c6421... got: b''
Executing: mac tx uncnf 1 48656c6c6f20576f726c6421... got: b''
etc etc
It just sits on the mac tx uncnf 1 line forever.

Solved my own problem. Needed to add an ‘\r\n’ to the send command.

Yep I think you are right, I will come back and let you know if it works. I imagine it will otherwise there would be a lot more people complaining. I think its just the way I read it.

SF and required SNR not matching
Did you enable ADR on the device, and does it send an ADRAckReq after 64 uplinks? If you can capture a full LoRaWAN packet from the gateway then you can easily check if an online decoder shows that FCtrl.ADR is set.
As for learning more: did you read the ADR documentation?

TTN Console stopped showing downlinks for TTIG
Looks like, I found the root of my downlink problems. The station uses ESP32 LoRa module. Before data transmission, a function to read sensor data is called, it contained delay() functions to give some inputs time to stabilize, well… it must be stupid idea to use delay() function in such place and time, looks like it messes up LoRa timings as it freezes CPU and parallel tasks are affected. I removed delay’s and at this time downlinks are working flawlessly, there are still some problems with OTAA Join process, as there are still some delay functions to replace. I’ll test it for few more days to be sure. but Yea - don’t use delay functions in your LoRa projects, as I did. Replace them with some millis / yield loops instead.

Graphing data
Have a look at ThingSpeak. There is now an integration from TTN. ThingSpeak provides 4 channels (8 fields each) free. Graphing is the default. Can’t speak highly enough of ThingSpeak, stores the data forever(![?]) unlike most of the other services.

SF and required SNR not matching
Yes, ADR is enabled and ADRAckReq is coming.
I am not sure if I can rely on that docu, because we are using a different network server.
