Downlink problem on Adafruit Lora M0 and TTN-GW-868

I’m wondering if I should just go to ABP instead.

Given your other forum posts, you want the downlinks to work properly anyway. Also, one may want ADR, which needs downlinks too. So, no, using ABP is just ignoring the real problem. (And it would introduce different problems, like if the device does not properly persist state between restarts.)

For the sake of completeness:

So, in any case, make sure you see the orange Activation icon in the device’s Data page in TTN Console (or the timestamp after the device’s Status label in TTN Console), to confirm that the Join Request uplink was received

…and: accepted. TTN might reject it if the configuration is wrong (in which case it would never accept it), or if its random LoRaWAN 1.0.x DevNonce was used before (which can be mitigated if one has done a lot of testing).

I see a bunch of messages with I think little lightning flash icons. I have been assuming those are join attempts from the node.

In the TTN Console Data page, those are OTAA Activations, so: the Join Request (which is only shown in the gateway’s Traffic page) was accepted by TTN, and a new DevAddr and secrets have been assigned. Hover your mouse over the icon to see “activation”.
