I have my feather lora M0 working perfectly on TTN using the example from the arduino-lmic library. Now I’m trying to get my feather lora 32u4 to work using the ttn-otaa-feather-us915 example, but I get a “no join accept” status from TTN. I selected the correct 32u4 lmic_pinmap . The DevEUI and APPKey are correct. APPEUI is set to zero. Pin 6 and DI01 are connected. I can see uplinks coming from my node. The lmic_project_config.h is correct. What else might I be missing?
Well, after several hours it started working. It intermittently joins and sends data, so I guess I’ll work with it and see if I can get it to work consistently.
So, every once in a while, the Feather 32u4 joins and starts sending data. Then it will quit again and won’t join again for several hours , if at all. This is what I’m seeing from the gateway:
Live data 11:41:16 eui-70b3d57ed004d388 Forward join-accept message 11:41:15 eui-70b3d57ed004d388 Accept join-request 11:41:09 eui-70b3d57ed004d388 Forward join-accept message 11:41:08 eui-70b3d57ed004d388 Accept join-request
The serial monitor just shows:
317554154: EV_TXSTART 317955961: EV_JOIN_TXCOMPLETE: no JoinAccept 318002417: EV_TXSTART 318382902: EV_JOIN_TXCOMPLETE: no JoinAccept
Again, every once in a while it will join and send data for a few hours. Anyy suggestions?
I had the same problem.
I installed an older version of LMIC library, v.3.2, and now it works !
Maybe you can try this.
Thanks, I’ll give that a shot.
How did it go? We have the same issue en masse here.
No solution. Apparently some problem with the Feather 32u4 and some library versions. I wasn’t going to fight it. I just switched to Feather M0 and it works perfectly.
