(Solved) Issue with Sodaq Autonomo/RN2483 ABP

[ubergesundheit]

Hi everyone,

I am using a Sodaq Autonomo with the attached RN2483 and I have the following problem:
After I register the device (ABP) through staging.thethingsnetwork, Packet transmissions works great. I see the messages on the website and also receive them through mqtt.

But after the third time or so I power the device, packets don’t get through ttn. I also have a Gateway (LinkLabs RPI Hat) here and the log says there are some forwarded packets but as I said, none of the packets come through.

If I then register a new device through ABP and transfer the Ids and Keys to the autonomo packets come trough until I unpower the device and repower it.

I am willing to give more details of both the node and the gateway to solve my problem.

Cheers,
ubergesundheit

Your node is sending outdated frame counters. See https://www.thethingsnetwork.org/wiki/LoRaWAN/Security and:

ABP node stopped working -> Fixed by creating new ABP.. Why?

Hi all! I have been playing with TTN for a week now and I have a working PROMINI (3,3v, 8mhz, 328) + RFM95 + u-blox GPS node. Everything is working as expected and I have been tracking my activity for a 2 days. The range is excelent btw, had some 10km+ frames near Lopik, NL (Gerbrandy tower) using a simple 86mm wire as an antenna. I registered my device using ABP and I send 1 frame every minute (only while traveling +- 100 frame per day), packing the GPS data into 2x32bit integers thus sending…

Aaah Thank you very much! Seems like a rookies error! Should’ve read the docs before jumping into the cold water
