I bought a new Raspberry Pi 2, a 8 GB memory card, and the SX1272 LoRa shield.

However I can't get your software to work on it. I get the following message from a sudo ./lora_gateway_pi2 call:

Unrecognized transceiver
...
...
...
... //forever

Installation process:

Downloaded and flashed Raspbian on the RPi2
Did a sudo apt-get update && sudo apt-get upgrade -y to get all new update for the Pi
Inserted the board into the Pi
Did a git clone https://github.com/CongducPham/LowCostLoRaGw.git in ~/
Because it is the Libelium and does not use inAir9, all lines in radio_makefile has a # (commented)
Build the software with make lora_gateway_pi2:

g++ -DRASPBERRY2 -c SX1272.cpp -o SX1272_pi.o
g++ _lrt -lpthread lora_gateway_pi2.o arduPi_pi2.o SX1272_pi2.o -o lora_gateway_pi2

Executed the file with sudo ./lora_gateway_pi2 and received the "unrecognized tranceiver" message.

So I thought something might be wrong with it. Looking into SX1272.cpp, line 145-165, the version of the unit is detected. But version gets the reading of 0x00 - absolutely nothing.

Perhaps the shield was broken? I unmounted the Libelium from the shield, and connected the pins to the RPi. But still the same message.

The Libelium is broken? I connected an oscilloscope to the SPI0_SCLK (PIN23), but the clock comes in small burst. Perhaps it sleeps? In setLORA(), line 456-513, the while loop printing the ... message does indeed do a delay(x) several times. These, and the printf("...\n") were commented, so the loop could write and read the SPI all the time - but the burst pattern on the oscilloscope did not change.

I tried 3 different RPi2s and two shield with different Libelium - it's all the same.

What can I do about it? It is like the SPI is broken to the SX1272.

CongducPham commented 8 years ago

Dear Rasmus,

Could you check the SPI connections? It seems that it may be a wrong connection. Or maybe did you enable SPI on the RPI? It should be done because it is not done by default.

So, I read through the bcm2538.h file again, and found out I need to download it aswell.

wget http://www.airspayce.com/mikem/bcm2835/bcm2835-1.49.tar.gz
tar zxvf bcm2835-1.49.tar.gz
cd bcm2835-1.49
./configure
make
sudo make check
sudo make install

I then enabled SPI - also as default on boot. Device-tree was already set to loaded, so it was not an issue.

I rebooted the Pi, and tried to do a new make of the files, but it is up to date. However, I receive the same output from the program.

Do you have other suggestions?

CongducPham commented 8 years ago

Dear Rasmus,

I don't see why you need to download the bcm2538.h file because it is already in the package.

I did have many reliability issues with the Libelium radios. This is one reason I'm using instead either the HopeRF or the inAir modules. Is the radio module working fine with the standard distribution and examples from CookingHack?

best regards,

No, you are correct. It present a small list stating it skipped the packet.

I tried an example from Cooking-Hacks - it worked. So out of curiosity I tried the LowCostLoRaGw file again and it now works properly.

So, it looks like I installed some files/libraries needed for the program to run.

I have a few RPis which needs this installed. I will be trying to see what might be missing from your installation instruction and create a pull-request to the readme.md if I find a concrete solution.

I think I located your problem, so I need you to confirm this.

Try to reboot your RPi, and just run the program. I am rather confident, that the SX1272 is not initialized correct, because it works after I run another program with a different setup. But if I then reboot, your program no longer works.

CongducPham commented 8 years ago

Dear Rasmus,

I have a gateway based on an RPI2 and I reboot it every time I use it. The radio is a Libelium, connected directly. I have no such issue. This radio module works fine from the very beginning. Some other modules from Libelium have random behavior and I don't know why. I have no issue at all with the HopeRF and inAir9. So I don't know exactly what's going on with the Libelium modules as I cannot discard completly a hardware issue.

Hi,

I faced a similar problem with the libelium's LoRa modules, and after a lot of chat with them, they told me to remove a resistor on the module and my module work pretty fine now. Here is an extract from the mail they sent to me -->" We think the issue is related of a resistor in the LoRa module that causes the malfunction. If you have some soldering skills it's an easy task, you should remove the resistor and shortcircuit the two pads with a tin bridge. We attach you a photo about the resistor." I ask them why this resistor would hurt the module and they told me: " The resistor is connected to a reset pin. With the resistor plugged, the module is not able to reset correctly. Removing it you wouldn't have problems."

I hope this can help you or someone else that use Libelium modules and face and 'unstability' issue.

Regards.

Hi Simon, thank you for this information, I'll try it on the 3 modules that have never worked in a stable way and will get back to you. If it works for me also then I will have 3 more LoRa module. But really, I find the modtronix inAir9 module much better and much cheaper.

Hi, I am currently using a Lora GPS HAT, 433MHz, and a Raspberry Pi3. Once I have followed your instructions, ran sudo ./lora_gateway_pi2 and I got unrecognized transceiver. Please advise on how to solve the issue. I know I have to edit the lora_gateway.cpp file, but am unclear on what to change. I have enabled SPI using raspiconfig. Apologies as my coding is very bad, I just started learning.

Hi, according to the picture on:

http://wiki.dragino.com/images/9/9b/RPi_GPIO.jpg

the LoRa hat is using GPIO6 for CS pin while our library use CE0 (next pin).

As indicated on the dradino wiki (see example 4), there are some modifications to make it work.

Hi, if you look at the SX1272.h file, you will see at the beginning the following lines:

if defined ARDUINO_AVR_PRO || defined ARDUINO_AVR_NANO || defined

ARDUINO_AVR_MINI || defined MK20DX256

define SX1272_SS 10

else

define SX1272_SS 2

endif

just to test, use only

//#if defined ARDUINO_AVR_PRO || defined ARDUINO_AVR_NANO || defined ARDUINO_AVR_MINI || defined MK20DX256

define SX1272_SS 10

//#else //#define SX1272_SS 2 //#endif

because maybe the define variable for the anarduino is not one of the mentioned above.

Hi @CongducPham, It is not a question but more a comment that may help someone else. I have a Lora module (RFM95/ SX1276) with a RP3. The module was used in an old project and the GPIO 25 (pin 22) of the RP3 was used for the CS pin, so when I tried to use your code, I have change the code to tell the program that GPIO 25 is used as CS instead of GPIO 8 (pin 24). Even after changing the code, I kept getting Unrecognized transceiver. After reading your comment about the LoRa Hat, I have welded pin 22 and 24 (and put back the code as it was) and the magic happened! everything works perfectly now!

Any reason why it doesn't work even after changing the code?! Thanks anyway. Mehdi

CongducPham commented 7 years ago

Hi, I believe it is because pin 25 is not accessed correctly by the ArduPi layer whereas pin 24 which is CE0 is referenced as CS and it is usually pin 10 on Arduino. So the mapping with ArduPi is correct. This is my guess.

Please read our README as our modified library is a bit different.

https://github.com/CongducPham/LowCostLoRaGw/blob/master/README.md

I believe your issue is because of the CS pin. It should on pin 10 on the pro mini. If you use our lib and our example it should work. Otherwise, change the CS pin to 10 in the original libelium lib.

Even after setting the SS pin there also occurs the same error like "Unrecognised transceiver"

CongducPham commented 7 years ago

Please check the SPI connection again, because it is the only reason I can see. Also, did you have the 3.3v version of the pro mini?

My controller is Arduino Pro mini with 5v and again the same error occurs as "unrecognised transceiver"

CongducPham commented 7 years ago

Maybe it is the 5v issue, the radio module requires 3.3v not 5v.

ARAVINDAARONE commented 7 years ago

but in the actual datasheet of sx1272 the supply voltagei is - (-0.5v) to (3.9v)

and the operating voltage is - (1.8v to 3.7v) i am supplying 3.5v to sx1272

CongducPham commented 7 years ago

You have to supply 3.3v not 5v, this is the issue with your board.

sorry sir its my fault, i made the connection in wrong way. Thank you for your help.

CongducPham commented 6 years ago

Check the CS pin, it should be pin 10 on the Arduino.

AntoineGirafe commented 6 years ago

I recently bought a new Raspberry Pi 3, a 32 GB memory card, and the SX1272 LoRa shield from libellium with the SX1272 LoRa Module.

I tried to use your software but it's not working returning :

Unrecognized transceiver
...
...
...
... //forever

Just after launching the options 1 of the cmd.sh : sudo ./lora_gateway --mode 1 I don't know why it's not working I followed "the step by step" tutorial ... Any clue about this error ?

CongducPham commented 6 years ago

Currently, the RPI3B+ is nor supported.

regards,

AntoineGirafe commented 6 years ago

Do you have any idea of how I could adapt your lib to use it on RPI3B+ ?

I get another library from libellium to make working the RN2483A module on RPI3B+, I think I could find something for the SX1272 too and then adapt it to make it work on RPI3B+.

Thank you for your help.

CongducPham commented 6 years ago

I believe the SX1272 lib is not an issue, it is probably a change in the architecture so lower level lib such as arduPI and bcm2835 may need to be changed.

AntoineGirafe commented 6 years ago

ok I will take a look ! the changes between RPI2 and RPI3 are :

Built in bluetooth and Wi-Fi
processor 1.2Ghz quad core (300Mhz faster)
Architecture 64 bits (previously 32 bits)
GPU and RAM faster (higher frequency)

Knowing that, do you have any idea of what could cause such problem in these two low level library ? I will investigate and try to improve it. Thank you again for you help !

CongducPham commented 6 years ago

The RPI3 is fully supported. Our distrib now targets mainly this platform. It is just the RPI3B+, the last one that we still not support or tested.

AntoineGirafe commented 6 years ago

OHH My bad, so it's normally working on Raspberry Pi 3 model B .... Great ! I will try again and come back to you if I get the same error with the RF module. Thank you !

AntoineGirafe commented 6 years ago

OK, so I tried again, same error than my first message

I tried to use your software but it's not working returning :

Unrecognized transceiver ... ... ... ... //forever

Just after launching the options 1 of the cmd.sh : sudo ./lora_gateway --mode 1

It's like the module wasn't detected... I'm using a cooking hacks shield for raspberry and the libellium module SX1272 I really don't know why it's not working with. Maybe should I try to connect it pin to pin just like in your exemple without a shield ?

CongducPham commented 6 years ago

You need to know on the cooking hack shield which pin is the CS pin. And yes, it is much better to avoid the shield.

AntoineGirafe commented 6 years ago

Concerning the CS pin on the shield, it's a direct link from the pin 4 of the SX1272 module pluged on it (DI012/SPI_MISO) and the pin GPI08 of the Raspberry 3 so it should work...

I will try it without the shield to be sure.

AntoineGirafe commented 6 years ago

OK I tested it and IT WORKED ! :-D the module is detected, I just need to find out where to configure the RF parameters to check if packets are received and it will be good !

In fact, I discovered that the cooking hacks shield for arduino and raspberry only works with RN2483A (LoRaWAN) module. The power pin is missing and I supposed the other pins are not correctly wired for the SX1272 module (despite the CS pin is correctly wired).

Next steps : try to make it works with a post processing system and replicate the process for the RN2483A module.

Thank's a lot for you help !
