Sodaq One - cannot register on TTN


Hello all,

I have just set-up a single channel GW on my RPi3 and trying to connect Sodaq One with tracking software to TTN . However, Lora initialisation fails:

Initializing LoRa...
[expectString] expecting RN.(RN2483 1.0.1 Dec 15 2015 09:38:09) found a match!
The device type is RN2483
[setMacParam] deveui = [array][expectString] expecting ok.(ok) found a match!
[setMacParam] appeui = [array][expectString] expecting ok.(ok) found a match!
[setMacParam] appkey = [array][expectString] expecting ok.(ok) found a match!
[setMacParam] adr = on
[expectString] expecting ok.(ok) found a match!
[expectString] expecting ok.(ok) found a match!
[expectString] expecting accepted.......(denied)LoRa init failed!

I did follow the guide on

However, I cannot connect to TTN.

I can see my router online at
B827EBFFFF0247FA active N/A now

I have otaa=1

Your help is appreciated

Any help highly appreciated!


Issue resolved here!

The mote (SODAQ One) is equipped with the US RF Chip RN2903.
Broadcast on 915 MHz is seen by my LORANK8 EU configuration according to the log.
But due to this mismatch, it cannot be received correctly :unamused:

Strangely, reconfiguring the LORANK8 to work with US frequencies does not resolve the problem either ... :scream:


Issue NOT solved :frowning:

Now using a SODAQ One Version 2 with correct RN2483 (FW 1.0.1) I still gett CRC_BAD errors on the LORANK8.
It seems to work with short (few bytes) messages, there I see CRC_OK. Larger transmissions generate CRC_BAD.
So OTAA does not work either :scream:


I never managed to get Sodaq ONE working on a single channel GW.
Had to get a proper GW and all works now.
