LoRaWAN & Arduino Pro Mini

[newuser]

I have Arduino Mini (called Pro Mini in AliExpress): Mega328 For Arduino TTGO T-Deer Pro Mini Lora V02: https://www.aliexpress.com/item/4000129694110.html?spm=a2g0o.productlist.0.0.4a1e1a532LjITj&algo_pvid=7c54a49a-69c3-49c1-adbc-eb3b5466bc8b&algo_expid=7c54a49a-69c3-49c1-adbc-eb3b5466bc8b-4&btsid=0b0a555916222159309254995e56b6&ws_ab_test=searchweb0_0,searchweb201602_,searchweb201603_

I've tested LoRa sender to receiver connection and it works. next I'm testing with LoRaWAN and I'm having problems.

I am using MCCI LMIC LoRaWAN library and the "TTN Otaa" example. I've set a "The Things Network" device. I've followed a youtube example setup: Building a LoRaWAN Node for The Things Network (TTN) - YouTube

Now when I'm running the example I get:
Starting
Packet queued
1906: EV_JOINING
29205: EV_TXSTART

When checking if something was received at "The Things Network" there is nothing.

I suspect that my pin mapping is wrong:
// Pin mapping
const lmic_pinmap lmic_pins = {
.nss = 10,
.rxtx = LMIC_UNUSED_PIN,
.rst = 5,
.dio = {2, 3, LMIC_UNUSED_PIN},
};

I've tested a number settings and above is the only one that does not cause error on Arduino serial monitor.

What could be the problem?

What could be the problem?

Your not close enough to a working Gateway.

Heyyy, it might a bit late but I would like to know if you have solved your problem successfully? I am facing same prob too, btw, did you check the frequency of your node and gateway..?

I changed to using only Lora (not LoraWAN).
