First Setup

[raymonvdm]

I`m just discovering the existence of LoRa and have bought an RFM95 and connected the following pin-out

` PI Port <<----------------->> RFM95 Port

3v3 = VCC GND = GND

GPIO10 = SPI_MOSI = MOSI GPIO9 = SPI_MISO = MISO GPIO11 = SPI_CLK = SCK

GPIO8 = SPI_SEL = nCS

`

The radio.makefile

` CFLAGS=-DRADIO_RFM92_95

CFLAGS=-DRADIO_INAIR9B

CFLAGS=-DRADIO_20DBM

`

The startup

./lora_gateway SX1276 detected, starting. SX1276 LF/HF calibration ... ^$**********Power ON: state 0 ^$Default sync word: 0x12 ^$LoRa mode 4 ^$Setting mode: state 0 ^$Channel CH_10_868: state 0 ^$Set LoRa Power to x ^$Power: state 0 ^$Get Preamble Length: state 0 ^$Preamble Length: 8 ^$LoRa addr 1: state 0 ^$SX1272/76 configured as LR-BS. Waiting RF input for transparent RF-serial bridge

How do i find out of the module is actually found / working? I have no working sensor device so it is difficult to test.

Note when i disable the power to the RFM95 i get "Unrecognized transceiver" so something is working. But did i need to set the GPIO pins somewere?

To test you need at least 2 radios, one for the gw (i.e. raspberry) and the other for a device that would send to your gw. Difficult to test with only 1 radio!

What do you mean by "... set the GPIO pins somewere?". Actually, only the SPI pins need to be connected, this is obviously what you did and it is working, so no need for other pins.

I`m no hardware tech. I just connected the wires as told abov. I though i needed to setup which GPIO pin has which RFM95 function. So which is PIN is MOSI and which one is MISO and so on.

I have on RFM95 and a Kerlink Gateway so i should be fine for some testing. But i cannot figure out how to use the PI as a node (yet) So i first try to make it a single channel gateway.

I also had a LoRA Test Sensor but is seems to be as dead as can be. In the beginnen there was a led blinking but now it is completly dead. So this is stopping my first test case.

Yes, SPI pins are already defined by hardware, so no need to assign anything.

The kerlink is running with LoRaWAN. So if you want to test, you can try using an Arduino as an end-device and try the lmic-arduino stack to make your arduino LoRaWAN with basic functionality. Then, you will not use our package anymore.

If you have the kerlink, probably that the best way for you is to use the LoRaWAN distrib and use for instance STM32 boards that are supported by the Semtech end-node code.

I also had a LoRA Test Sensor but is seems to be as dead as can be. In the beginnen there was a led blinking but now it is completly dead. So this is stopping my first test case.

Sorry I don't use this platform.

Check OpenLora forum or TheThingNetwork for LoRaWAN related issues with your kerlink gateway.

Hi, As mentioned in other topics, I am using the Lora GPS Hat, 433Mhz. I am unsure on how to edit the code (lora_gateway.cpp) to work with 433Mhz, understand that the code is mainly for 868 and 900Mhz.

From what I have read from the code, in the radio.makefile, I have to uncomment the last one.

CFLAGS=-DRADIO_RFM92_95

CFLAGS=-DRADIO_INAIR9B

CFLAGS=-DRADIO_20DBM

But I am unsure about this (lora_gateway.cpp), as my Lora Hat doesnt fall under these: // please uncomment only 1 choice // // it seems that both HopeRF and Modtronix board use the PA_BOOST pin and not the RFO. Therefore, for these // boards we set the initial power to 'x' and not 'M'. This is the purpose of the define statement // // uncomment if your radio is an HopeRF RFM92W or RFM95W //#define RADIO_RFM92_95 // uncomment if your radio is a Modtronix inAir9B (the one with +20dBm features), if inAir9, leave commented

define RADIO_INAIR9B

Am unsure of this too, am using 433Mhz, so do I need to do this: "#define BAND 868" // please uncomment only 1 choice

define BAND868

//#define BAND900

Under the lora_gateway.cpp file, I have to "// Select frequency channel". I am using 433Mhz, so do I have to change all the 868 values to 433?

Not sure about what else to delete in the lora_gateway.cpp file that is redundant.

Hope to receive your reply for guidance soon! Thank you so much. So sorry for constantly troubling you, I'm very bad at coding, still trying my best to learn.

You can do a quick test. Please read:
