Hi there, I’m new to LoRa and have a brand new 868MHz TTN Uno which I kinda expected to work out of the box, it’s supposed to connect to TTN and show up on their ttn.fyi/activate map - it doesn’t. I assumed it would connect though one of the Calderdale community gateways but perhaps I’m expecting too much range? So I then tried it in Hebden Bridge also without success. Is there anything I’m missing?
Be very grateful for any help.
Thanks.
My brand new TTN Uno does not show up on the ttn.fyi activate map.
The board is working, I see two green LEDs, I also see the expected serial output info appear every minute:
> – SEND: INTERVAL
> Go to: https://ttn.fyi/activate
> EUI: 0004A30B002413DE

> RX Delay 2: 2000
> Sending: mac tx uncnf 12 0004A30B002413DE
> Successful transmission
There 3 gateways within 3km range of me, I have also re-tried within 500m of one of these gateways.
I have an 868MHz TTN Uno operating the UK at postcode HX7 5TB.
Any help or suggestions much appreciated.
please follow these instructions
Thanks, but I was following these, Step 1, instructions:
Are you saying these instructions are no longer valid?
Just trying to walk before I run.
did you connect it to The arduino IDE ?
Yes, but only to use the serial monitor, which behaves as expected, I did not flash the board or load any sketches.
try to register the device… see if everything works first and if its not related to network operational issues.
OK but then I’d have to flash over the default sketch. Is there a way back, is the code of the default sketch available anywhere?
Well before I do that I’d rather try to understand why the board is not doing what it’s expected to do.
That’s what I thought we could test (for example… is the onboard LoRa module working as expected, if not you could never connect) but it’s clear that you’re after the source of the manufacturers sketch… again, you won’t find it, I’m sorry.
Per your other post if you are “in” Cragg Vale, then even with the 3 GWs within 3km you will get nowhere fast! The topography is against you and you will need to move your test node much closer to a GW & in line of site…will post map to show your problem shortly when I get a few mins… Even LoRa can’t penetrate a few km of rocky hills 
Perhaps set up your own GW?
Approx geography with rough positions of you and GW’s…
Calderdale topographic map, relief map, elevations map
I suspect that it is possible to read out the currently flashed hex file via the bootloader in order to archive it and possibly put it back later; it is definitely possible with avrdude and a board based on an ATmega328p and the standard Arduino bootloader (the “verify” process is actually a readback), I suspect it can also be done with this, which being 32u4 based is really more of a “Leonardo” than an “Uno” but am not finding a good writeup where someone has demonstrated it.
If you were going to do that you’d probably want to get the EEPROM contents too, as there might be configuration and state information there.
Of course it’s absurd if the default software of a community-involved device like this is not public; TTIG has the same inexplicable problem.
Overall your best route to success would probably be to see if someone with one of the local gateways could help you. If you can get near it with the board and your laptop, while they have the gateway’s raw traffic page open on their computer, then you can see if the gateway picks up anything at the time when your node transmits. It’s possible to at least partially decode the raw packets to see if they make sense as either ABP or more likely OTAA traffic.
wow… could you elaborate on that, I’m sure its very usefull information for a lorawan beginner
Thanks to all for your help, I’m very grateful for your support. I joined the Calder Valley TTN Community but am struggling to figure out how to contact anyone there other than through this forum. It would be great to see if my Uno’s transmissions were being received by a gateway, and try to figure out why the default sketch isn’t working as expected. Any pointers as to how to contact a friendly gateway owner would be appreciated.
Have you reached out to @9600 Andrew Black? andrew@abopen.com The local TTN Initiator
https://www.thethingsnetwork.org/u/9600
He owns the Hebden Bridge GW.
Note I see from the map that Ripponden GW is down at the moment so you wont get any joy pinging messages through that one! 
Also I see Gavin Wagstaff has an intermittent (TTIG) GW near you close to one of Andrews other GW’s and can be contacted using the Contact button on his profile https://www.thethingsnetwork.org/u/gavin-wagstaff
…Ah the beauty of a community! 
Thanks again Jeff, I know that Andrew is a busy man, I was reluctant to intrude on him by email, but I’ll give it a go. Appreciate the help.
There will be a lot of geeks in Hebden Bridge next week, including me, that is where Wuthering Bytes is;
Jeff, thanks for this, I will clearly have to setup my own g/w. However, I just spent the last 4 hours in and around Hebden Bridge which, according the TTN map, has coverage from at least 5 gateways. I was carrying the Uno around attached to my Android phone running a serial monitor to check transmission every minute. Still no sign of the device on the ttn.fyi/activate map.
Borroz, according to serial dump from the Uno’s (secret) default sketch the on-board RN2483A module is working as expected:
> Sending: mac tx uncnf 12 0004A30B002413DE
> Successful transmission
I assume there would be an error message here if it were not transmitting.
did you create an application and added your node in the console ?
Sadly I’m away for most of the Wuthering Bytes days, but will try to get along at some point.
Thanks for the reminder.
