Hi Drew,
Do you have a gateway nearby? And do you know what settings it might be running?
Did you resolve your issue with the failed JOIN? I am just trying this project and I get the same error. I have 3 of my own gateways so there is no issue on distance with my set up.

I tried changing the DR=0 to DR=1 but when it first connects it still says it is using DR=0.
+DR: DR0
+DR: US915 DR0 SF10 BW125K
+JOIN: Start
+JOIN: NORMAL
+JOIN: Join failed
+JOIN: Done
Join Failed
Although in my case it did not JOIN so it never sent the message. When your device connects doe it change from DR=0 during the JOIN to DR=1 when it sends the message?

Hi there, sorry for the delay. Are you sure that the change to DR is being saved? I have not worked with this device for a while, but if I remember correctly, there is a command to save the settings and there is a command to show current settings. Maybe try this to ensure DR=1
Just to be clear though I did not have an issue with join, the issue which DR=1 fixed was the length of the data

I may have been too quick to post. It turns out I had a typo in the DEVEUI and that is why it would not join, however it always posted the DR=0 when it failed to join. Once I fixed the DEVEUI, it joined no problem and the DR=1 was posted. I am not sure why there is a difference, maybe timing? I know timing is everything with LoRa.
Thank you for the reply!

Great tutorial, Tim! I am interested in making calculations out in a field based on ML and hence will deploy a RPi 3B. Would this system work for a bigger Pi? If not, what would you suggest?
Hi Prithul,
Welcome to the forum! You can certainly use this setup on a Pi 3, you will need to some tweaks to Tim’s example.
Hi Jack,
Thanks for confirming! I am fairly new to using PiHats and LoRaWAN. Could you kindly guide me in understanding the tweaks in terms of hardware? I wanted to order parts to start working on this project as I mentioned. Did not want to make the novice mistake of ordering the wrong things.
Regards,
Prithul
You’re welcome!
To connect up our PiicoDev sensors to the Pi you can use this adapter. The other hardware should be the same.
Thanks for that, Jack. Your support is much appreciated 
Keep up the good work!
Regards,
Prithul
