Hello, This is Nori from Japan.
I have a Multitech Conduit gateway(GW) and a Dragino LoRa mini Dev endnode(EN), and
am trying to implement OTAA and downlink algorithm. I’ve been using ABP algorithm. So
this is my first try for OTAA.
Currently I have a problem. The problem is :
(1)My EN can NOT join the session.
(2)My EN can NOT transmit data.
(3)My application can NOT receive downlink data.
Here are more information about my developing environment.
For (1), I refer to the code ttn-otaa-downlink.ino, which was originally created by Thomas
Telkamp and Matthijs Kooijman, and slightly modified, use some part of the code. Especially
follow onEvent (). After running the code, it shows on the serial monitor “EV_JOINING”, and “EV_JOIN_FAILED”, never shows “EV_TXCOMPLETE”. TTN GW console shows Join Request and Join Accept, but never shows Data. TTN APPL console just shows “Activation”.
For (2), as told above my EN never tells “EV_TXCOMPLETE”.
For (3), I can schedule downlink data from TTN console. I usually send 2 bytes data. When
I tried downlink with ABP session, I could see data reception on TTN APPL console. This time I can see scheduled data, but NOT see received data on TTN APPL console.
Any suggestion will be welcomed.
