TTN only receive application data once

Wong_Cheah · January 3, 2021, 7:03pm

Hi, I’m new to TTN. I tried to create a LoRa Node ( Cytron LoRa-RFM Shield & CT-UNO) and setup LoRa gateway(Cytron Lora Gateway Raspberry Pi Hat 915Mhz HAT-LRGW-915). I follow this link to setup my gateway and it able to connect to TTN.

In one week before I succes to gather data from sensor device to TTN.
But today it suddenly cannot recieving anything new application data. When I recompiling the Arduino code, the status of device in TTN reactive. And receive once data shown in TTN application tab. In past I can receive repeated data and the counter will kept incresing.

Do any expert or senior know the reason cause this?

Your node firmware is defective if it keeps transmitting with a frame count of zero and not incrementing; this is not in compliance with the LoRaWAN specification, and it is not really going to work.

Also it was a mistake to buy 915 MHz components if you are going to operate on 868 MHz.

I change all to Australia with 915 MHz but failed to connect

Then I tried United States915MHz still failed to connect

You can’t just go changing frequency plans like that!

First you determine what is legal for your location.

Then you source hardware built for that frequency range.

Then you configure it for the particular plan of using something within that range which TTN uses in your locality.

Wong_Cheah · January 4, 2021, 7:03am

I stay in Malaysia. So I have to use frequency 919MHz to 923MHz right?

In this list, I better choose Asia 920-923 MHz and Korea 920-923MHz

915MHz LoRa Gateway Raspberry Pi Hat able to receive LoRa signals within frequency range from 900MHz to 930MHz (center frequency 915MHz).

RFM95W LoRa module operating in the 915 MHz frequency band

Is that mean I have to change my frequency plan to Asia 920-923 MHz or Korea 920-923MHz?
How about the ttn console router and LoRa Gateway Raspberry Pi Hat global and local json file?

I tried this command and only bridge.eu.thethings.network connect successfully to port 1883

cslorabox · January 4, 2021, 4:53pm

You cannot just base this on what is done in other countries in your region, first you need to determine what is actually legal in your country.

I tried this command and only bridge.eu.thethings.network connect successfully to port 1883

What you can reach on the Internet has essentially nothing to do with what frequency plan you need to be using

kersing · January 4, 2021, 5:32pm

The port might be different on different clusters. You can try port 1882.

Wong_Cheah · January 5, 2021, 4:26pm

Sorry, I’m just new in this.

Cslorabox how to determine what is actually legal in my country? Which way can configure it for the particular plan of using something within that range which TTN uses in my locality?

After setting the frequency plan and router selected, my global(https://github.com/PiSupply/iot-lora-gw-pktfwd/tree/master/lora_templates) and local (“server_address”: “router.< region >.thethings.network”) json fie how should I update.

Wong_Cheah · January 5, 2021, 4:27pm

Ok thank you Kersing I will try it

NorHairil · November 18, 2021, 7:03am

Hi, Wong Cheah. Sorry I maybe late but have you settle the problem?

cwchawt2000 · December 28, 2021, 6:17am

how to program 915mhz to work on 923MHZ ?thx

cslorabox · December 28, 2021, 2:34pm

You don’t. As was clearly explained in the message you seem to be responding to, you cannot simply change the frequency.

Instead, you must use software that knows about the entirety of the needed regional settings plan, which is far more than just frequency.

So the first thing you need to do is find out which one is applicable to your mystery location, and what it is called. Then you need to see if your software supports that.

It seems that what you’re actually trying to do involves Helium and not TTN, and probably the wrong hardware at that, so your question doesn’t seem to be on topic here anyway.
