TTN v3 don't recieved ABP uplinks messages (UNCONFIRMED UP)

[G-3r4-d]

Hello everyone, Im trying to connect an ESP32 LoRa V2 (sensor-node) to TTN V3 using another ESP32 LoRa V2 as a single channel gateway using this library https://github.com/things4u/ESP-1ch-Gateway . I made a test using the otaa example file, the TTN server recieves Join messages but the gateway is no going to send me any downlink messages due to its nature.

So, I'm using ABP example file to test connectivity to my sensor-node. The gateway recieves an UNCONFIRMED UP messages from the sensor-node. Any idea how to solve this?

Im using

• Arduino IDE 1.8.13
• ESP32 Wifi LoRa V2 (SX1276)
• Arduino-LMIC v4
• Frecuency plan AS923
  This information is very important; it's hard to help without a complete set of answers.

Thank you

As explained at #785 since channel "gateways" are prohibited by TTN

Hello. Thank you for your answers.

I finally managed to solve my problem.

I abandoned my single channel gateway and bought a TTIG (The Things Indoor Gateway). After it's initials configurations, my end node started to send its data, via OOTA and ABP, to my application.

Before buying the TTIG, I did one final attempt with the single channel library, creating my own private LoRaWAN network server with Chirpstak. It had the exact same problem as TTS LoRaWAN server. No packages to the application server.

I know single channel gateways are not well recived by LoRaWAN community in general, I was just trying to develop a project using all my resources. As I said previously, I gave up that idea and decided to gain enough money to afford a suitable gateway TTIG

Hi @G-3r4-d, very glad you solved the problem, and sorry you had difficulties. One of the issues for me is that my resources are also extremely limited; and testing is very time consuming. I have no objection to single channel gateways, per se, but I think it's not a good use of time to support them here, when there are outsanding compliance bugs in other areas. Thanks for your understanding.

You are absolutely right @terrillmoore. Thank you for your understanding.
