Should this page not be updated to include the 3.3v connection and the move away from the TTN Croft? (Everything is outdated as it's uploaded these days!) Great site btw - super content.

I have problem getting rid of the "unrecognized transceiver" error message when running the compiled binary. I'm using Raspberry Pi 3 with v1.3 of the LoRa Shield. Not sure whether this is the reason why...

dragino V1.3 doesnt use 5v, it uses 3.3 v instead

dont connect dragino pin 23(5v) with raspi pin 2(5v)
connect dragino pin 22(3.3v) with raspi pin 1(3.3v)

Baxter, thank you. I've connected p22 to p1. LED on lora shield has been lighted. But I still receive "unrecognised transiever". Have you got any ideas?

Hi sir!
I'm trying to use the Lora module I bought to build a gateway.
The module is SPI interface and it work successful with Arduino, the sample code I use is from :
And then I saw the project of using Pi and Dragino Lora module to build a gateway also with SPI interface.
But the Raspberry Pi can't read my Lora module but Arduino.
I used the SPI test sample code from Raspberry forum, the test result showed the Pi can read from arduino but nothing from Lora module.
Here's my module:
Could you tell me where did I go wrong?

Please note that the used has been deprecated. It's no longer maintained and above all: has never supported downlinks, and hence no OTAA either.

My gateway uses the same configuration above but operates at 915 MHz. I am using the single channel packet forwarder code by tfelkamp.

My gateway only the detects the first message it received and ignores the all messages afterwards. It is still connected to the TTN server but does not receive anymore messages.

Can anyone explain what might be the cause of this?

hai..for raspberry pi 3 you need to change eth0 to wlan0 to change the gateway id..tq

Hi, is there a way to transmit data from Smartphone via WiFi to LoRAWAN gateway and then from the LoRAwan gateway to the Desktop PC? If yes how?

Dear sir
Can i control from gateway to end-node?
Thank for supporting me!

hello! can you help me about my lora gateway!!! it work but still not connected on TTN

Can I use Orange PC (with H3 processor ) in this project instead Raspberry Pi 3 model B ?

Nice tutorial. i want to know if i can create a Lora gateway using Raspberry Pi 3 and Lora module RFM95W and just skip the dragino shield?

what change do i have to make for frequency 915mhz

I have been trying to send my water flow sensor data to the ttn server through ABP using the hello world sketch but haven’t been successful on it. I am using HPD13A SX1276 wireless transceiver LoRa module along with ATmega328 microcontroller and the LoRa gateway is constituted manually which includes Raspberry Pi (2B), LoRa transceiver (SX1276- RFM95/ HPD13A) and Internet enabled Ethernet connectivity.

I am confused that where should i put my flow sensor code ( which reads the sensor data on a real-time basis) in the hello world sketch so that it sends it to the ttn server or is there any other way i can send my flow sensor data to ttn.

I had also referred DHT sensor data transmission to TTN sketch from the youtube video but couldn’t get anything out of it.
