Hi,

I am using LMIC library (arduino sketch from Thomas Telkamp and Matthijs Kooijman) to join TTN network in Australia.
Whisper node messages are arriving on TTN console under device EUI. 

Yet, join request returns EV_JOIN_FAILED in arduino monitor. Is there a compatibility issue, version???
 
TTN Console sample for device:
{
  "time": "2018-03-28T21:33:57.469032398Z",
  "frequency": 917.5,
  "modulation": "LORA",
  "data_rate": "SF8BW500",
  "coding_rate": "4/5",
  "gateways": [
    {

      "channel": 8,
      "rssi": -28,
      "snr": 9.8
    }
  ]
}

Hi,

Looks like you're very close to getting it working. Are you trying to use OTA registration? Could share the TTN Library Link and Example code you're using?

Also, have you performed the hardware modification described in this post: https://www.thethingsnetwork.org/forum/ ... -dios/9148?
