No, LoRa is not some kind of WiFi. Instead, a device just transmits and hopes that one or more gateways receive its transmission and forward that to, e.g., The Things Network. If the device does not request confirmation then it won’t get any either.
Again, please be more specific; we cannot know all hardware that exists, and surely we cannot just guess how you programmed that hardware.
Maybe you just tested with LoRa (the radio modulation), not LoRaWAN (the standardised network protocol that uses LoRa)? But if you programmed that TTGO-LORA32-V2.0 hardware to be a single-channel test gateway which you also connected to TTN, then if data is shown in TTN Console then you also know that other gateways could receive your node’s transmissions. However:
Things like “Packet queued” really only refer to your device; the sketch has created a LoRaWAN-compatible packet and delegated that packet to the LoRa chip that will transmit it. It does not tell you if one or more gateways have received it; the device really does not know. So, given this logging and without knowing where you’re located, we cannot know if there are any gateways in your neighbourhood. Peeking at https://ttnmapper.org and https://www.thethingsnetwork.org/map might give you a clue, but the actual range might be worse.
Assuming you did not use the TTGO-LORA32-V2.0 as a single-channel test gateway, then I’d suggest:
- Forget about TTN Mapper for now
- Read about the spreading factor; https://www.thethingsnetwork.org/docs/lorawan/#modulation-and-data-rate
- Make your sketch use SF12 for the first tests
- In TTN Console and in your sketch use ABP, not OTAA
- Disable the frame counter checks in TTN Console
Now, if you’re lucky that there are indeed TTN gateways in your neighbourhood, then you might see some data in TTN Console. Next, decrease the spreading factor to see if you still receive data.
If this doesn’t work at all, and if you don’t know if there’s a proper gateway in your neighbourhood then for your first tests I’d suggest to use the TTGO-LORA32-V2.0 for a single-channel test gateway. Note that you’ll only receive messages that are transmitted on the channel and spreading factor that such single-channel test gateway is listening to, while a proper node will use different frequencies for each transmission. So, such single-channel test gateway is only for your first tests, to ensure that the node is working.
Or maybe just some other device (like smart metering) that uses LoRa, not even LoRaWAN.
